The Earth and the Solar System
Solar system is the group of heavenly bodies comprising the sun and the nine planets.
The origin of the Solar System
A theory is a set of reasoned ideas intended to explain facts or events
1. Passing Star Theory
• A star with a greater gravitational pull passed near the sun
• It attracted large quantities of gaseous materials from the sun
• The materials split, cooled and condensed to form planets
• The planets were set in orbit by the passing star
• Doesn’t explain the origin of the sun and star.
• Minimal chance of a star approaching another
• Materials would disperse than condense
2. Collision Theory
• Star with greater gravitational pull passed near the sun
• It attracted large quantities of gaseous materials
• The materials split into portions
• Large portions collided with smaller ones and swept them to form planets.
The weaknesses are the same as the passing star’s Theory.
3. Nebula Clod Theory
• There was a slowly rotating cloud of dust and gas called Nebula
• It cooled and began to contact
• Rotation speed increased and successive rings of gaseous materials were formed.
• The rings condensed to form planets
• The central gaseous material remained as the sun
• Rotation and revolution of planets in anticlockwise direction Weakness
The origin of nebular is not explained.
4. Supernova/explosion Theory
• There was a violent explosion of a star.
• A cloud of dust (nebular) remained from the star.
• There was fast movement of the cloud due to the force of explosion.
• Rotation speed increased due to gravitational attraction
• The cloud flattened into a disc.
• The matter began to accumulate towards the centre to form a proto-sun which later began to shine.
• The rest of the cloud collapsed to form planets.
• Doesn’t explain the origin of the star
• Doesn’t explain the cause of explosion

3. Places in the east see the sun earlier than those in the west.
4. When a ship is approaching the smoke is seen first, then the mast and finally the whole ship.
5. All the planets are spherical so the earth being one of them is also spherical.

• Equatorial diameter-12756km
• Equatorial circumference-40085km
• Polar diameter-39995km
• Surface area of the earth-510×106 km2
• Water surface-73%.
The Movement of the Earth
There are 2 movements of the earth namely:
1. Rotation of the earth on its axis
2. Revolution of the earth around the sun
Rotation of the Earth
-Movement of the earth on its own axis (imaginary line through the centre from N pole to S pole.
• Rotates through 360◦.
• Takes 24 hours (day) to complete 1 rotation.
• Rotates in an anticlockwise direction (west to east).
Effects of Rotation of the Earth
1. Creates day and night because at any one time one side of the earth faces the sun (day) and the other remains in darkness (night).
2. Causes deflection of winds and ocean currents in the N hemisphere to the left and in the S hemisphere to the right.
3. It causes rising and falling of ocean tides.
4. Causes time difference between longitudes.
• Takes one hour to go through 15◦.
• 4 min to go through 1◦.
Calculation of Local Time
-The time recorded in places within the same longitude.
A longitude is an imaginary line running from N to S which shows how far E or W a place is from the prime meridian.
Greenwich Meridian (0◦) longitude is the point of reference when calculating time.
Time is gained towards the E and lost towards the W.
1. Suppose the time at GWM is 12 noon what is the local time at Watamu 40◦E?
Time gained=40×4=160min=2 hours 40min
Local time at Watamu is 12.00+2.40=14.40-1200=2.40pm.
2. At Dar-es-Salaam 40◦E time is 12pm what is the time at Ecuador 40◦E?
Ecuador is behind in time =12.00-4=8 am.
If the places are on the same side subtract the degrees to get the difference and add or subtract from the reference time depending on which side the place is.
Calculation of Longitude
What is the longitude of place x whose local time is 8 am when local time at GWM is noon? Time difference =12.00-8=4 hours Degrees=4×15=60◦ Since x is behind in time its then 60◦W.
Standard Time and Zones
• Standard time is time recorded by countries within the same time zone.
• Standard time was come up with due to confusion resulting from time changing at every longitude.
• The world has 24 time zones.
The International Date Line It’s the 180◦ longitude.
Effects of Crossing It
• One gains time when he crosses it from W to E and has to adjust the clock ahead by 24 hours.
• One loses time when he crosses it from E to W and has to adjust the clock backwards by 24 hours.
Revolution of the Earth
• Movement of the earth in its orbit around the sun.
• It’s in anticlockwise direction.
• The orbit of the earth’s revolution is elliptical.
• Takes 365 ¼ days in a year or 366 days in a leap year (every 4 years).
• The sun moves from the tropic of cancer to the equator and then towards tropic of Capricorn and back to the tropic of cancer.
• 21st march and 23rd September are called equinoxes because the length of day and night is equal. The sun is vertically overhead at noon at the equator.
• 21st June is called summer solstice because its summer in the N hemisphere. The sun is vertically overhead at noon at the tropic of cancer.
• 22nd December is called winter solstice because its winter in the S. hemisphere. The sun is vertically overhead at noon at noon at the tropic of Capricorn.
• Solstice is the period of maximum tilting of the earth towards the sun.
1. Causes the four seasons summer, autumn, winter and spring due to the movement of overhead sun causing changes in the heat belt.
2. Causes variation of day and night’s lengths due to the earth’s axis being inclined to the path of revolution at an angle of 60◦.
• Equinoxes have equal lengths of day and night.
• Summers have longer days and shorter nights.
• Winters have longer nights and shorter days.
• Highest altitude during equinox
• Lowest altitude during solstices
4. Causes lunar eclipse due to revolution bringing the earth in line with the sun and the moon.

b) Plants use carbon dioxide from it for photosynthesis.
c) Water vapour in the atmosphere condenses to form clouds which give us rain.
d) Ozone layer in the stratosphere shields us from ultraviolet radiation which may cause cancers.
e) Carbon dioxide and methane in the atmosphere cause global warming through the green house effect.
b) The Hydrosphere
• Part of the earth’s surface covered by water masses e.g. oceans, seas, lakes, rivers and even underground water.
• It comprises 73% of the earth’s surface area.
• The atmosphere and hydrosphere are related in that atmospheric gases penetrate to the ocean depth in solution form.
• The lower atmosphere, hydrosphere and the upper part of the earths crust are called biosphere meaning the sphere of the earth in which organic life exists.

• Mercury pushes the index up.
• When temperature falls mercury contracts.
• The maximum temperature is read from the scale at the lower end of the index.
• Thermometer is reset by shaking it to force mercury back into the bulb.
It uses alcohol.
How it’s Used/Works
• Temperature falls causing alcohol to contract.
• Alcohol pulls the index down.
• When temperature rises alcohol expands and rises in the tube.
• The index remains where it was pulled.
• Minimum temperature reading is obtained from the scale at the lower end of the index.

How It Works
• Spherical lens focuses light on sensitized paper.
• The paper burns when the sun is shining.
• The total hours of sunshine is got by adding all the burnt sections from calibrations on the side of sensitized paper.
• The sensitized paper is changed every day.
Humidity is the condition of atmosphere with reference to its water content.
It’s measured with hygrometer or psychrometer which consists of wet and dry bulb thermometers kept in Stevenson screen.
Dry bulb thermometer is a thermometer covered with muslin bag immersed in water while dry bulb thermometer has no muslin.
How It Works
• When air is dry there is a lot of evaporation from the muslin.
• Evaporation cools the bulb of thermometer resulting in a low temperature reading.
• When humidity is high there is little evaporation from the muslin.
• The wet bulb thermometer is cooled at a slower rate and both thermometers show almost the same temperature reading.
• The difference in readings between the two thermometers is used to determine relative humidity.
• When the 2 readings are the same, relative humidity is 100% i.e. the air is saturated.
• If the difference is small, humidity is high.
• If the difference is big, humidity is very low.
- Actual amount of water vapour a given volume of air can hold. It’s expressed in g/m3.
- Mass of water vapour in a given mass of air. It’s expressed in g/km.
- Ratio between the absolute humidity and the maximum amount of water the air can hold expressed in a percentage.
R.H.=A.H/Maximum amount of water the air can hold at the same temperature.
• If the air at 20◦c contains 10g/m3 and given air can hold a maximum of 20g/m3.calculate the relative humidity.
How It Works
• As the wind blows the arrow swings.
• The arrow points in the opposite direction of the wind flow.
• The direction is read from the cardinal compass points.
• The arrow will point in the direction from which the wind is blowing.
• For instance if it points S the wind is blowing from S towards N.
- Not kept in a weather station because it doesn’t give the accurate direction of wind flow.
- Seen near airstrips for the benefit of pilots.
How it Works
• When wind blows the bas stretches out in the direction that the wind is blowing.
How It Works
• When wind bows hemispherical cups rotate.
• The number of rotations is obtained from the metre on the lower part of the anemometer.
• The units for measuring wind are called knots.
-The force exerted by gases in the atmosphere on some area or body on the earths surface.
-Measured using barometers of three types namely mercury, aneroid and Fortin Barometers.

• The readings are taken in mmHg.
• Its 760mmHg at sea level
1. Cumbersome to carry around.
2. Can be damaged quite easily while being carried around.
-Measures changes in atmospheric pressure.
How It Works

• Compartment expands when pressure decreases.
• It collapses when pressure increases.
• The movement is transmitted by lever to a pointer on a dial.
• The readings are in kg/cm3.
The rate and amount of evaporation is measured using piche and tank evaporimeters.
• The level of water in the glass tube reduces.
• The rate and amount of evaporation is got by looking at the scale on the outside of the glass tube.
• The units are in mm.
• The tank with water is put in the open.

5. Use of faulty instruments.
6. Human error.
7. Poor sitting of instruments.
Factors Influencing Weather
Factors influencing temperature
-Height above sea level.
• Temperature decreases with increase in height due to air at higher altitude being thinner and hence there is less particles e.g. gases, dust, smoke and water vapour to store heat so its rapidly lost to the outer space.
- Distance from the equator.
Temperature decreases with increase in latitude.
• Places neat equator experience high temperature due to the rays of the sun travelling a shorter distance facing less interference from atmospheric conditions hence more solar energy reaches the earths surface.
Also the rays of the sun strike the earth at right angles hence solar energy is concentrated over a small area.
• At higher latitudes the rays of the sun travel a longer distance facing more interference from atmospheric conditions hence less solar energy reaches the earth’s surface.
Also the rays of the sun strike the earth at an acute angle hence solar energy is spread over a large area.
3. Aspect - Direction of slope.
• At higher latitudes slopes facing the equator have higher temperature because they face the sun while those facing the poles have lower temperature have lower temperature because they face away from the sun.
- Transfer heat from one place to another.
• When they blow from cool areas they take the cooling effect to the areas they blow over and when they blow from warm areas they take warming influence to the places they blow over.
5. Distance from a Large Water Body
• Areas near a large water body experience lower temperature during the hot season and higher temperature during the cool season due to sea breezes, warm and cold ocean currents and wind blowing over water which could be either warmer or cooler than the adjacent land.
6. Cloud Cover
• Clouds reduce the amount of solar energy reaching the surface by absorbing, scattering and reflecting solar radiation.
• When there are clear skies during the day the temperature is higher due to the earth receiving maximum solar insolation.
• During clear nights there are very low temperatures due to a lot of terrestrial radiation being lost to the outer space.
• Cloudy nights on the other hand are warmer due to clouds radiating to the earth heat absorbed during the day.
7. Length of Day
• The longer the period of solar insolation the greater the quantity of radiation a place receives and hence the more the heat that will be generated by the earth and vice versa.
8. Solar Altitude
• At equinox when the earth is farthest from the sun the temperature on the earth is lower due to less solar radiation reaching the earth’s surface due to travelling a longer distance and hence facing great interference from atmospheric conditions.
• At solstices the earth receives more solar energy due to travelling a shorter distance and hence facing less interference from atmospheric conditions.
9. Solar Input
• Sometimes the sun gives out more heat due to reactions being violent causing temperature on the earth to be higher.
• When it gives out less heat the temperature on the earth is lower.
10. Surface Conditions
• Light surfaces e.g. smooth surfaces reflect sunlight and hence less solar energy reaches the earth’s surface.
• Dark and irregular surfaces such as with vegetation absorb more heat leading to higher surface temperatures.
Factors Influencing Humidity
• Places with high temperature experience high humidity due to high evaporation and air having high capacity to hold moisture.
• Places with low temperature have low humidity due to low evaporation and air having low capacity to hold moisture.
2. Source of Moisture
• Areas near water bodies e.g. Kisumu and Mombasa experience high humidity due to evaporation of water from the water body.
• Places near thick vegetation also have high humidity due to evapo transpiration.
• Areas far away from water bodies such as the middle of deserts have low humidity.
• Areas receiving heavy rainfall also have high humidity.
3. Air Pressure
• There is high humidity at low altitudes because high pressure compresses air warming it increasing its capacity to hold moisture and also causes high evaporation.
• There is low pressure at high altitudes because air expands and cools thus reducing its capacity to hold moisture.
• Low latitudes experience high humidity due to high temperatures resulting into high rates of evaporation and air having high capacity to hold moisture.
• High latitudes experience low humidity due to low temperatures resulting into low rates of evaporation and air having low capacity to hold moisture.
Significance of Humidity/Moisture
1. Affects rain formation in such as way that places with high humidity are likely to experience higher rainfall than those with low humidity.
2. Regulates the heat loss from the earth’s surface by absorbing terrestrial radiation (process in which the earth gives off heat into the atmosphere).
3. It affects sensible temperature in that the higher the humidity the more we experience sensible temperature.
-The forms in which the earth’s surface receives moisture.
Solid precipitation formed when tiny water droplets freeze and form ice crystals.
The crystals may fuse to form flakes.
-Precipitation which is a mixture of rain and snow.
Roughly spherical lumps of ice formed when super cooled cloud droplets mould themselves around ice crystals before cooling. It destroys crops life and house roofs.
-Precipitation consisting of water droplets formed on cold surfaces at night e.g. iron roofs and glass blades.
How It’s Formed
• In a clear night there is a high ground radiation.
• Temperature of the earth’s surface fall below dew point (temperature at which air being cooled becomes saturated).
• Excess water condenses on cold surfaces.
-Precipitation consisting of water drops/droplets formed when tiny water droplets merge around particles of matter and become heavy and fall down to the earth.
Turning of water vapour into tiny water droplets as cooling continues below dew point. The droplets join to form clouds.
Causes of Condensation
1. Adiabatic cooling-cooling of moist air as it rises vertically.
2. Orographic cooling-cooling of moist air as it climbs a hill or mountain.
3. Frontal cooling-cooling of warm air mass when it blows towards a cold air mass.
4. Advection cooling-cooling as a result of moist air moving over a cool land or sea.
How Condensation Takes Place/Cloud Formation
• Moist air rises to the condensation level (altitude where temperature is below dew point.
• It’s cooled below dew point.
• Tiny water droplets condense around tiny particles such as dust, smoke particles and pollen grains and salt particles (condensation nuclei).
• The droplets merge and eventually become bigger and fall as rain.
• If moisture rises to an altitude where temperature is below 0◦c the condensed water droplets freeze forming ice particles or super cooled water (water which has remained in a liquid state at temperatures below freezing point due to lack of sufficient condensation nuclei.
• Super cooled cloud droplets may mould themselves around ice crystals before freezing to form hail.
Types of rainfall
1. Relief/Orographic/Mountain rainfall
How it Forms
• Moist air is forced to rise over a hill or mountain.
• The temperature and air pressure decreases making it to expand.
• Air cools due to decreased temperature and decreased pressure causing it to expand.
• Moisture condenses forming tiny water droplets (clouds).
• The tiny water droplets in clouds merge and become too heavy to be suspended in air and fall as rain.
• Air proceeds to the leeward side with low moisture content.
• Since its heavier due to being cool it descends over that side and gets warmed making it to hold onto the little moisture it had causing that side to receive low rainfall (rain shadow).
1. Convectional Rainfall
It’s accompanied by thunderstorms.
How it forms
• Ground or water body is heated causing evaporation.
• There is convective rising and cooling of moist air.
• Condensation takes place forming tiny water droplets (clouds).
• The droplets merge and fall as rain.
• The cooled dry air descends to the surface where its heated and its capacity to hold moisture is increased.
• The process is repeated.
2. Frontal/Cyclonic Rainfall
It’s accompanied by cyclones (violent winds).
How it Forms
• Warm moist air mass meets with a cold air mass.
• The warm air is forced to rise as it’s less dense.
• It cools as it rises at the line of contact with cold air.
• The moisture condenses forming clouds resulting in frontal rain.
Factors Influencing Rainfall Types and Amounts
Relief features such as mountains and hills results in the rising and cooling of moist winds to form relief rainfall.
Windward slopes which are on the path of rain bearing winds receive heavier rainfall than leeward slopes which face away.
3. Forests and Water Bodies
Areas near forests and large water bodies experience higher rainfall and more often due to high rate of evaporation.
4. air pressure
High pressure areas receive low rainfall than low pressure areas due to pushing of air masses from high pressure to low pressure. The high pressure areas have descending dry air.
5. air masses
When warm and cold air masses meet frontal rainfall is formed.
6. Ocean Currents
• It influences rainfall whereby coasts washed by warm ocean currents experience heavy rainfall when moist onshore winds are warmed by the current and made to hold on to moisture which they release on reaching the land.
• The coasts washed by cold ocean currents on the other hand experience low rainfall as a result of moist winds being cooled and moisture in them condensed resulting in rain falling over the ocean thereby bringing little or no rain to the coastal areas.
This is the cause of western margin deserts e.g. Kalahari and Namib deserts.
Factors Influencing Atmospheric Pressure
• Pressure decreases with increase in altitude because the column of air becomes shorter hence it exerts less weight.
• When air is heated it expands and exerts pressure over a large area resulting in reduced pressure.
• When it’s cooled it contracts and exerts pressure over a small area resulting in increased pressure.
2. Rotation of the earth
• Rotation pushes air masses from poles towards the equator causing air to spread out and occupy more space causing it to expand making pressure to decrease.
• When air from the equator moves towards the poles it occupies less space causing it to contract resulting into high pressure.
Mist and Fog
Mist and fog are a mass of tiny water droplets suspended in the lower layers of the atmosphere.
Fog is denser than mist i.e. has more moisture.
Both hinder visibility although fog reduces visibility to less than a kilometre.
When fog mixes with smoke its called smog.
How They Form
• Moist air cools below dew point.
• Condensation takes place.
• The resultant water droplets remain suspended in the air.
Types of Fog
1. Radiation Fog
• Type formed when moist air is cooled below dew point as a result of intense radiation on the ground at night.
1. Advection Fog
• Type formed when moist air from the sea moves horizontally over a cold surface e.g. snow covered ground.
2. Orographic/Hill/Upslope Fog
• Type formed when moist air is cooled after climbing a hill or mountain.
3. Evaporation Fog
• Type formed when water vapour is added to cold air that is already near saturation causing excess water vapour to condense and form fog.
4. Frontal Fog
• Type formed when warm moist air is cooled from below as it rises over a cold air mass.
5. Steam Fog
• Type formed when moist air passes over the surface of a much warmer fresh water body.
• The warm water is cooled from above and condensing water vapour forms fog. It appears to be steaming.
6. Ice Fog
• Type formed when water vapour is converted directly into ice crystals when temperatures are below freezing point.
-Are a mass of tiny droplets or ice particles formed when water vapour condenses.
Three Cloud Forms

• Bring heavy rains when onshore which can cause severe flooding.
• Well developed in the Indian Sun-continent, china, Japan and S.E Asia.
- Distinct large parcels of air moving in one direction
- Originate from areas of uniform weather and topography from where they derive their characteristics e.g. flat areas, forests, deserts, and snow covered areas.
Characteristics of Air Masses

• Forms near sub-tropical high pressure belt.
2. Polar Air Mass
• Forms near the poles or temperate low pressure zone.
• It’s cool.
3. Arctic and Antarctic air Masses
• Forms over the ice sheets of Greenland and Antarctica respectively.
4. Effect of air masses on Weather
• When warm moist air mass and cool air mass meet cyclonic rainfall is formed e.g. tropical maritime and polar maritime.
• Cool air masses take cooling effect to the areas they move to e.g. polar continental.
• If they are warm they take warming influence to the area they move to e.g. tropical continental.
Pressure Systems in the World
• Starts in areas where air ascends from the ground to the atmosphere and descends at high altitude.
• It’s of two types. Tropical cyclones e.g. hurricane, typhoon and willy willies and depressions which are characterised by temperate latitudes.
• The movement of wind is anticlockwise in the N. hemisphere and clockwise in the S. hemisphere.
• • It starts in areas where air is descending from the atmosphere onto the ground and then blows outwards on the ground.
• The movement of wind is clockwise in the N. hemisphere and anticlockwise in the S. hemisphere.
-Which occur regularly for a short period of time affecting a limited area.
-Modify the weather of the area they blow to.
1. Sea Breeze
How it Forms
• During the day land is heated faster than the sea.
• Air over the land is warmed and rises.
• Air from the sea moves to the land to replace the rising air.
• The rising air from the land cools and descends over the sea at high altitude.
• Circulation continues until the pressure difference is reversed at night.
Effects on weather
It takes cooling effect on land on a hot afternoon.
2. Land Breeze
-A light and gentle wind which blows from land to the sea during the night.
How it Forms
• Air over the sea is warmed and rises.
• Air from the land moves to the sea to replace the rising air.
• Rising air from the sea descends over land at high altitude.
• Circulation continues until pressure difference is reversed during the day.
Effects on weather
It causes early morning showers through moisture brought towards land at high altitude.
3. Anabatic winds (Valley Breeze)
How it Forms
• During the day hill tops are heated more than valley bottoms.
• Air over the hill tops is warmed and rises.
• Cool air over the valley move up to the hill to replace the rising air.
Effect on weather
- Cause afternoon showers on hilly grounds.
4. Katabatic/Descending Winds
• During the night hill tops lose heat faster than the valley.
• Air over the valley is warmed and rises.
• Cool air over the hill tops move to the valley by gravity to replace the rising air.
Effect on Weather

5. Harmattan Winds
-N.E winds which originate from Sahara and blow across W. Africa between November and March taking dry conditions there.
6. Fohn Winds (Alps)
-Local cold winds which slide down the leeward side of the mountain at high speed and are warmed producing a temperature rise.
Due to the high speed and temperature they are associated with wild fires.
They are known as Chinook in Rocky Mountains, Santa Anas in California and Mistral in France.
Factors influencing Wind Flow (Speed and direction)
1. Pressure Gradient
If the pressure difference between high and low pressure areas is high the winds blow at high speed (strong) but if it’s low they blow at high speed (are gentle).
2. distance between Places of High and Low Pressure
if the high and low pressure areas are near each other winds blow at high speed but if distant from each other winds blow at low speed.
3. Rotation of the earth
Rotation of the earth deflects winds to the right in the N. hemisphere and to the left in the S. hemisphere.
4. Frictional Force
If the surface of the earth is rugged or has obstacles such as hills, mountains, valleys or vegetation the wind is blocked causing speed reduction and its direction of flow is also changed.

Types of Sampling
1. Random Sampling
- Selection of members of a group haphazardly where every item has an equal chance of being selected e.g. to select 5 students to go for a tour from a class:
• Class members write their names on pieces of paper
• They are folded and put in a basket
• The basket is shaken and fives papers are taken out
2. Systematic Sampling
-Selection of members of a sample from an evenly distributed phenomena at regular intervals e.g. after every 10 items/members.
3. Stratified sampling
-Selection of members of a sample by breaking the population into homogenous groups e.g. to select 6 students to go for a tour:
• Break the class into boys and girls
• Select 3 student from each group by random or systematic sampling
• Combine units from each group to form the required sample.
4. Cluster Sampling
-Selection of sample by dividing the sample into clusters with similar characteristics then a sample is taken from each cluster and representative choices from each cluster are combined to form a sample e.g. to sample the housing cost an estate is chosen to represent each group and representative choices are chosen from each estate and combined to form a sample.

• Alternative/Substantive hypothesis (H1)
- One stated positively e.g. ‘most foodstuffs sold in the neighbourhood don’t come from the immediate neighbourhood’.
Quantitative words should be used e.g. more, most, majority.
It should not be obvious.
5. Preparation of the Field Study
a) Seek Permission from Relevant Authorities

• Laboratory testing of samples
• Presentation of data using methods such as graphs, pie charts, etc.
Problems Encountered in Field work
1. Language Barrier
-Inability to communicate due to the interviewer and the respondent not sharing the same language or respondents may be illiterate and thus unable to fill questionnaire.
The problems are:
• Data may not be collected
• Illiterate people may give wrong answers while attempting questionnaires
• An interpreter may have to be engages who would be paid which would raise costs.
• Answers may be distorted by the interpreter
Those being approached to give answers may become harsh due to feeling that their time is being wasted which would cause the field study to be unsuccessful.
3. Dishonest Respondents
- Respondents giving wrong information due to suspicion fear of shame or superstition.
4. Bad Weather
Raining heavily making it impossible to proceed with data collection and difficulty in movement.
Becoming very hot making participants uncomfortable and thus unable to proceed with data collection smoothly.
Becoming misty or foggy causing invisibility problems.
5. Accidents in the Field
One may fall and get inured when walking on rugged areas.
Injuries may result when using tools to get samples by cutting using pangas or knives and digging using hoes.
6. Attacks by Wild Animals
- Participants may encounter wild animals when carrying out the study in bushy areas e.g. snakes which may bite them, rhinos which may charge at them, etc.
- physical barriers such as swamps, rivers without bridges, steep slopes and thick vegetation may hinder participants from reaching areas with vital information.
Minerals and Rocks
- Inorganic substances occurring naturally at or below the earth’s surface.
Characteristics of Minerals

Non-ferrous Minerals - copper, aluminium, gold, lead, etc.
Non-metallic Minerals - graphite, diamond, asbestos, coal, etc.
Energy minerals - petroleum, coal and uranium.
-A consolidated material composed of grains of one or more minerals.
Classification of Rocks
1. Igneous Rocks
-Rocks formed when molten material from the earth’s interior cools and solidifies on or beneath the earth’s surface.
Types of Igneous Rocks a) Intrusive Igneous Rocks
-Rocks formed when magma cools and solidifies below the earth’s surface e.g. granite, diorite, gabbro, peridotite.
-Have coarse texture as a result of slow cooling giving minerals more time to form large crystals.
- Are classified further into two:
(i) Hypabyssal rocks - intrusive igneous rocks which are near the earth’s surface.
(ii) Plutonic rocks
- intrusive igneous rocks which are deep below the surface.
b) Extrusive Igneous Rocks
- Rocks formed when lava solidifies on the earth’s surface.
- Have fine texture due to fast cooling giving minerals less time to collect together to form larger crystals.
They are of two types namely:
(i) Volcanic Ejecta
- Extrusive igneous rocks formed in the following ways:
• When ash and lava ejected from underground as they fall on the earth’s surface e.g. pumice.
• When dust and ash ejected settle on the ground and get compressed to form a rock e.g. tuff.
(ii) Lava Flows
-Extrusive igneous rocks formed when basic lava flows over a considerable distance then cools and solidifies e.g. basalt and obsidian.
2. Sedimentary Rocks
-Rocks formed when particles of other rocks are laid down and compressed into layers or when plant and animal remains are buried and compressed and compacted.
• When they are laid down a layer is formed.
• As deposition continues additional layers are formed which compress the lower layers into a hard mass.
Types of Sedimentary Rocks
a) Mechanically Formed Sedimentary Rocks
-Sedimentary rocks formed when weathered igneous or metamorphic rocks are deposited and compacted e.g. sandstone and shale.
b) Organically formed Sedimentary Rocks
- Sedimentary rocks formed when animal and plant or animal remains are buried, compressed and compacted.
Classification of Organically Formed Sedimentary Rocks
(i) Calcareous rocks-rich in calcium carbonate e.g. chalk and limestone.
Coral rocks are formed from remains of sea polyps which extract lime from the sea, build shells for protection, attach themselves to each other and rocks to live in colonies, then die and shells to form coral rocks.
(ii) Ferruginous Rocks-rich in iron e.g. ironstone.
(iii) Siliceous Rocks-rich in silica e.g. diatomite.
(iv) Carbonaceous Rocks-rich in carbon e.g. coal.
c) Chemically formed Sedimentary Rocks
- Sedimentary rocks formed when materials dissolved in water chemically react forming new substances then water evaporated leaving layers of those salts.
Classification of Chemically Formed Sedimentary Rocks
(i) Carbonates e.g. trona and dolomite
(ii) Sulphates-sulphate compounds
(iii) Chlorides e.g. halite
(iv) Silicates e.g. flint
(v) Iron stones e.g. haematite and limonite.
3. Metamorphic Rocks
- Rocks which have changed their physical appearance and chemical properties as a result of subjection to great heat and pressure e.g.
• Gneiss from granite
• Slate from clay
• Marble from limestone
• Quartzite from sandstones
Distribution of Major Rocks in Kenya
Eastern Kenya region
• The major rocks are metamorphic rocks e.g. marble in parts of Machakos and schist and gneiss in parts of Kitui.
• Volcanic rocks in Yatta plateau and Kapiti plans.
• Sedimentary rocks e.g. limestone rocks used in Bamburi for cement manufacturing.
• Major rocks are sedimentary rocks e.g. limestone used in Bamburi for cement manufacture.
• There are volcanic rocks in Tsavo rich in ground water resources.
Northern and N.E Region
• Dominated by sedimentary sands.
• There are volcanic rocks in Mt. Marsabit and around Rift Valley.
Rift Valley and Kenya Highlands
• Dominated by volcanic rocks
• There are metamorphic rocks which have resulted from changing of igneous rocks.
L. Victoria Basin
• Granite and gneiss dominate Western Kenya where they form high rocky hills called granitic tors common in Kisii, Maragoli and Bunyore areas.
• Sedimentary rocks deposited by rivers e.g. Nyando, Nzoia, Yala and Sondu.
Significance of Rocks
1. Rocks weather to form soil which is important in agriculture.
2. Form aquifers which store ground water which forms springs which form rivers and wells which provide water for domestic and industrial use.
3. Some rocks are sources of building materials e.g. igneous rocks are used to make ballast and limestone rocks are used as building blocks and raw material in cement manufacturing.
4. Phosphate and nitrate rocks are used to make fertiliser used in agriculture.
5. Granitic tors of W. Kenya and high volcanic peaks such as those of Mt. Kenya are a tourist attraction which brings foreign exchange.
6. Pumice is used as a scrubbing stone.
7. A rock such as coal is used as fuel for heating, smelting of iron and thermal electricity generation.
8. Source of minerals e.g. oil and coal is associated with sedimentary rocks.
- Process of extracting valuable minerals from the earths surface.
Formations in Which Minerals Occur
1. Veins and Lodes
- Occurrence of minerals in crevices, cracks or faults in igneous rocks.
• They are said to occur in veins if they occur there in small quantities.
• Said to occur in lodes if they occur there in large quantities e.g. zinc, copper and silver.
- Veins and lodes which are exposed on the surface.
-Occurrence of minerals as sedimentary or as a result of compression of accumulated organic or inorganic material e.g. coal and halite.
4. Alluvial Deposits
-Occurrence of miner als while mixed with materials such as sand, gravel, silt, etc.
These were minerals which were detached from the veins by weathering and carried away by streams and rivers and got deposited e.g. gold, diamond and platinum.
5. Weathering Products
- Minerals formed by deep weathering of rocks then leaching carried minerals from the top to lower layers where they accumulated e.g. aluminium, nickel, iron and manganese.
6. Oil pools/Wells
-Occurrence of minerals in pools or wells in sedimentary rocks e.g. petroleum and natural gas.
Conditions Necessary for Formation of Petroleum
b) Presence of sedimentary rocks for burying organic remains.
c) Presence of pressure to compress organic remains to cook the oil and natural gas out of organic matter.
d) Presence of a porous reservoir rock to store and transmit petroleum to the oil pools e.g. limestone and sandstone.
e) Presence of a trap like a syncline to hold petroleum in a reservoir to prevent its escape.
f) Presence of impermeable rocks below the trap or syncline to prevent petroleum from percolating further underground.
Factors Influencing Exploitation of Minerals
1. Value of Mineral
Minerals of high value will be mined even if they occur in small quantities because one sold it will be possible to offset mining costs and make a profit and vice versa.
2. Quality of Ore
Mining can be done if the mineral deposits have high mineral content because they are economical to work on but deposits with low mineral content are rarely worked on except if the mineral in them is rare e.g. uranium.
3. Size of Deposit
Minerals which aren’t of high value have to occur in large quantities for them to be mined so that it will be a possible to recover mining costs and make a profit.
Lack of capital causes developing countries not to exploit minerals and leave it to international companies because a lot of money is needed for exploration, infrastructure, salaries, energy etc e.g. titanium mining at Kwale is being done by Tiomin company from Canada.
5. Method of Mining
A mineral requiring open cast mining will be mined even if the mineral deposit is large but one requiring underground mining will be extracted if its in large deposit or if its of high value or rare.
6. Transport costs
Minerals occurring in remote areas far from the markets are not likely to be exploited if the transport system is poorly developed since mineral ore is heavy and bulky and transporting it by road and railway is expensive.
7. Market for the Mineral
Mining can be done if the mineral is in demand and if the prices are reasonable so that mining costs are offset and a profit is realised.
8. Political Influence
Mineral deposits at the borders of two countries may not be exploited as a dispute may arise concerning whom mine it e.g. dispute between Iraq and Kuwait over Rumaila should oil field.
Exploitation of some minerals require skilled workers and if they lack it may not be done as is the case in developing countries because expatriates have to be engaged and are very expensive to pay which may reduces the profits accruing from mining.
Methods of Mining
1. Open Cast Mining
-Method of extracting minerals which are near the earth’s surface.
Types a) Stripping
-Stripping off of the unwanted material lying on top of the mineral deposit and then digging to remove the mineral bearing rock if it’s soft or if it’s hard explosives may be used to loosen it and then huge power shovels are employed to dig up the mineral deposits.
b) Hill-slope Boring
-Using boring instruments known as augers to drill out mineral deposit and bring it to the surface.
2. underground Mining
-Method employed when the mineral lies very deep below the surface and the overburden is too thick to be removed by mechanical means.
a) Shaft Method
- Method employed when the mineral bearing rock doesn’t out crop.
• Vertical shafts are sunk into the earth’s crust to reach the layer with the mineral.
• Horizontal tunnels are dug from the vertical shaft to reach the mineral.
• Props are erected to support the roof to prevent it from collapsing.
• The mineral bearing rock is blasted loose by explosives.
• The deposit is transported on light rail or conveyor belt to the bottom of the shaft.
• It is then brought to the surface in a crane or a lift called cage.
a) Drift/Adit Mining
-Method employed when the mineral deposit can be reached from the valley sides.
• Horizontal tunnels (adits) are constructed from the side of the hill.
• Railway line is constructed into the mine to bring out the mineral e.g. mining of copper at Kilembe in Uganda.
b) Solution Method
- Method used in mining soluble minerals such as sulphur, salt, potash, etc.
• Superheated water is ejected into salt deposits.
• The mineral dissolves or melts.
• The solution is then pumped into the surface.
-Method employed in exploitation of petroleum.
• Wells (oil derricks) are drilled.
• Oil and natural gas are brought to the surface under their own pressure or by pumping.
3. Alluvial/Placer Mining
-Method used to extract minerals occurring in alluvial deposits e.g. gold, tin, diamonds and platinum.
• Digging a mixture of sand, gravel and mineral from the river bed.
• Putting it in a pan and rotating the pan while tilted.
• The lighter sand or gravel is washed on the side leaving the heavier mineral at the bottom of the pan e.g. gold mining in Migori and R. Morun Beds in W. Pokot.
• A dredger scoops water logged alluvium from the bed of a lake.
• The alluvium is passed over sloping channels with series of traps.
• Wastes are washed away and denser materials are left at the bottom of the trap e.g.mining of soda ash at L. Magadi.
c) Hydraulic Mining - Method used when alluvial deposit occurs on a valley side.
• A powerful jet of water is directed at the deposit.
• Gravel and mineral collect at the valley because of the great pressure.
• The mineral grains are recovered and washed out.
d) Sub-marine Mining
- Method employed in extracting minerals in alluvial deposits lying deep down the ocean floor.
• A sub-marine dredger goes down the ocean floor.
• It scoops mineral deposit and rises to the surface.
• The alluvium is passed over sloping channels with series of traps.
• Wastes are washed away and denser materials are left at the bottom of the trap.
Significance of Minerals/Mining in Kenya
1. Kenya earns foreign exchange from exportation of minerals which is used to import goods and services and fund development projects.
2. Mining is a source of employment to people such as those who work in mines, in cement factories, in transport sector, etc.
3. Mining has led to development of industries by providing raw materials used in those industries e.g. limestone used in cement factories, coal used in iron and steel industries, soda ash used in glass industry, etc.
4. Mining has led to development of transport system to make mining areas accessible e.g. Magadi soda mine is connected to the main Mombasa-Nairobi railway line.
5. Mining has led to development of settlements e.g. Magadi town which originated from the mining of soda ash.
6. Mining is a source of market for goods and services e.g. there are shops and markets, banking and insurance services offered to people working in mines and related industries.
7. Has led to development of social amenities by providing social facilities such as housing, health, electricity, water and education alongside infrastructure.
Distribution of Minerals in E. Africa
Phosphates used in the manufacture of fertiliser-Tororo in Uganda and Majingu Hill in Tanzania.

Problems Facing Mining Industry in Kenya
1. Inadequate capital making Kenya not to benefit from mineral resources because mining is left to multinational companies who pocket all the money to recover mining cost.
2. Areas where mineral deposits are inaccessible due to poor transport and infrastructure which makes prospecting and mining difficult.
3. Insufficient skilled personnel causing dependence on expatriates who are expensive to pay which reduces profits accruing from mining.
4. Most of mining is controlled by foreign companies so most of the mineral revenue ends up to them as salaries and dividends.
5. Occurrence of minerals in very small deposits which are not economically viable.
6. Lack of power supply especially in remote areas with minerals.
7. Land use conflicts which affect mining e.g. in Kwale between Tiomin and the local people due to inadequate compensation.
Effect of mining on the Environment
1. Renders land useless for other economic activities such as agriculture (dereliction) due to open pits left on land and heaps of rock waste litter dumped on land.
2. Pollutes the environment e.g. atmospheric pollution from dust and smoke from tractors and trucks, water pollution from spilling of oil from offshore oil drilling and soil pollution from chemicals and explosives used in mining.
3. Leads to loss of bio-diversity due to destruction vegetation which also destroys habitats of various animals leading to their destruction also.
4. Causes soil degradation e.g. by loosening the soil which makes it vulnerable to agents of erosion like wind and water, tractors and trucks compact the soil making water infiltration difficult and chemicals used interfering with soil chemical composition making it unsuitable for agriculture.
5. Causes mass wasting when explosives and heavy equipment used in mining shake the ground making weathered materials to move faster down slope under the influence of gravity.
Trona mining on L. Magadi
L.Magadi is 120km S.W of Nairobi on the floor of the Great Rift Valley.
Trona deposits occur as a solution of sodium salts the main ones being sodium sequicarbonate and sodium chloride.
Mode of Formation
• Rain water dissolves soda salts in volcanic rocks.
• The solution percolates through the rocks and soil and gets beneath the basin.
• The accumulated solution is heated by the hot rocks beneath.
• Pressure builds up and the heated solution is pushed to the surface.
• It comes out of the ground inform of hot springs below or on the sides of the lake.
• Due to high temperature water evaporates leaving behind crystals of trona.
Extraction and Processing
• A dredger scoops trona out of the lake.
• It crushes it into smaller pieces and separates it from rock debris.
• The material is mixed with water to form slurry and transported to factory on the lake’s shore.
• In the factory the slurry is mixed with water to wash out impurities such as mud and salt and dried.
• It is sent to desiccators and heated to remove moisture and hydrogen to form soda ash.
• Soda ash is cooled and ground into powder and sieved.
• It’s packed into paper bags, weighed and transported to the market.
Uses of Soda ash
Used in the:
a) Glass industry in the manufacture of glasses and bottles.
b) Manufacture of soaps and detergents.
c) Softening water in paper making.
d) In textile industry.
e) In oil refining.
Benefits to the Economy
1. Has led to growth of Magadi town ship.
2. Has led to development of social amenities such as hospitals and schools and water from Oloibortoto River which has benefited the local people.
3. Has led to development of infrastructure e.g. railway line from Konza to L. Magadi.
12. The Magadi Soda Company employs many Kenyans including the nomadic Maasai.
13. Exports of soda ash earn Kenya a substantial amount of foreign exchange.
1. Stiff competition from developed countries with large soda deposits e.g. U.S.A and Israel.
2. Low value of salt is insufficient to meet its production cost.
3. High labour costs due to incentives given so that workers agree to work in the hostile environment of L. Magadi.
Gold in S. Africa
Gold occurs as small grains in a hard rock.
It’s mined by shaft mining since its bearing rocks are deep below the surface.
The main mining area is the Witwatersrand and others are Ogendaalrus and lydenburg.
• Ore is crushed to a fine powdery dust.
• Mixed with water until it is fluid mud.
• Cyanide is added to dissolve gold.
• The fluid is runoff with gold dissolved leaving behind waste salts.
• Zinc dust is added to filter gold for solidification.
• Gold sinks as it is denser.
• Gold is smelted and cast into ingots.
Significance to the Economy of S. Africa
1. Earns the country foreign exchange used for paying foreign debts.
2. Offers employment to many people raising their living standards.
3. Has led to widespread urbanisation contributing to formation of Witwatersrand conurbation.
4. Has formed a broad market for other industries e.g. engineering, foot wear, electrical and construction industries.
5. Has led to improvement of infrastructure and social amenities e.g. roads, schools, hospitals, etc.
6. Led to development of agriculture.
Problems Facing Gold mining
1. Expensive to mine for lying deeply.
2. Large capital is required to start mines.
3. Complication of mining by folds and faults in the crust.
4. Low gold content in the ore.
5. Problem of removal of underground water.
6. Lack of adequate supply of fresh water on the surface in mining areas.
7. Accidents resulting from collapsing of mine roofs.
Diamond Mining in S. Africa
Diamond is the hardest known substance.
-Mined in Kimberly, Bloemfontein and Alexander Bay.
-Mined by underground mining or alluvial mining.
• Diamond bearing kimberlite is crushed
• Crushed rock is mixed with water
• Diamond sinks to the bottom as it’s denser
• Water and less dense residue are drained off
• Remaining material is put on heavily greased trays and washed
• Diamond repels water so it sticks to grease while remnants are drained off
• Diamonds are then sorted out and graded into gem diamonds and industrial type (for cutting purposes).
Contribution to the Economy
1. Provides employment to thousands of people
2. Earns the country substantial foreign exchange
3. Has led to growth of urban centres e.g. Pretoria and Kimberly.
4. Has contributed to development of infrastructure
Problems Facing Diamond Mining
1. Fluctuation in the world market prices
2. High cost of mining and processing diamond
3. depletion of mines
4. Low mineral in the ore making mining expensive
5. labour competition with other sectors e.g. manufacturing and gold mining
Petroleum in the Middle East
Oil is a thick black sticky liquid called crude oil
• It was formed from small creatures that lived in shallow lagoons about 100-200m ago.
• Decaying remains of those creatures mixed with mud at the bottom as sediments
• The sediments piled on each other and slowly transformed into sedimentary rocks
• Gradually the remains were converted into oil and gas.
Major oil producers in the Middle East are Saudi Arabia with the largest reserves, Iraq, Kuwait and United Arab Emirates. V Middle East accounts for 64% of world oil reserves.
There are several giant oil fields in Ghawar in Saudi Arabia and Kirkuk in Iraq.
Crude oil is processed by refining using a technique called fractional distillation.
The process takes place near as possible to the market as it’s cheaper to transport crude oil than the different refined products.
It’s processed into secondary products such as petrol, paraffin, lubricating oils, dyes, fertilisers and plastics.
• Impurities are removed from the crude oil
• Crude oil is heated before entering fluctionating column
• It’s turned into vapour or gas
• Different ingredients turn back to liquid at different temperatures.
• Ingredients gradually cool, condense and collect in various trays and allowed to overflow until they reach an outlet.
Contribution to the Economies
1. Arab’s investments overseas have increased due to oil reserves.
2. High income per capita due to oil profits.
3. Has led to development of cities e.g. Tripoli in Libya.
4. Investment of oil money in other sectors e.g. power stations, cement factories and exploitation of other minerals.
5. Earns the countries substantial foreign exchange
6. Increased political and military power.
7. Artesian water is made available for domestic and irrigation purposes e.g. in Libya.
8. Oil companies help in fixing down the sand dunes and planting trees in the deserts.
