312/1,312/2 BURETI SUB COUNTY JOINT EVALUATION TEST Kenya Certificate of Secondary Education 312/1 GEOGRAPHY PAPER rmation obtained by geographysicists about theEarth?s magnetic fields, gravity and vibration of the earth helps geographers in understanding the causes and effects of earthquakes.-Physics deals with aspects of matter, energy, light, heat,sound gravity and magnetism, similarly geography while studying the atmosphere focuses on the heat from the sun, which is responsible for the movement of air, evaporation of water and distribution of moisture in the atmosphere.2.Five proofs that the earth is spherical-Circumnavigation of earth along a straight path leads oneto the starting point from opposite direction.-The gradual emergence of a ship approaching the shore.-The circular shadow cast by the earth during lunareclipse.-The different times during which the sun rises and sets indifferent parts of the world-The appearance of the middle pole to be relatively higherthan other poles placed along a straight line on level ground at equal distance.-The earth is planet and all other planets are spherical-The circular shape of earth seen on photograph takenfrom satellites in the outer space.3.a) An air mass is a large volume of air whosetemperature and humidity are fairly uniform and which covers an extensive surface area.b) Four characteristics of ITCZ-High humidity-High rainfall-High temperature-Low pressure-The belt where trade winds converge-Shifts North or South of the equator with the apparentmovement of overhead sun.4.a) Hotsprings are places where

evidence by markersc)Explaining four reasons why the region to the West ofEasting 27 is densely settled.-There are many transport lines e.g. all weather roadloose surfaces for the easy movement of goods and services hence dense settlement-There are many rivers which provide water for domesticuse as evidence by the many streams and seasonal swamps hence dense settlement-Gentle slopes as evidenced by spaced contours provideideal situation for the construction of houses/settlement -High rainfall as evidenced by the many permanent riversis ideal for crop growing / other economic activities. d) Describing the drainage of the area covered by the map-There are many rives-The main river is Sio-Most rivers are permanent-Most rivers in the East flow towards the West/River inNorth flow towards the South.-River Sio and its tributaries form dendritic drainagepattern / most rivers exhibit dendritic pattern. -there are many seasons swamps-there are many reservoirs-some rivers in the East drain to the swamps.7.a) A river capture is the diversion of the headwater of aweak river into the system of a stronger adjacent river whereas river rejuvenation is the renewal of the erosive power of a river.b) i) Three factors facilitating river erosion-steep gradient of the rive valley / high velocity of theriver.-high volume of water-Soft river bedrock-High/huge amount of load / large amount of loadii) Two types of deltas-Arcuate delta-Birds foot delta-Estuarine delta-Inland deltac)depositionErosionThe river begins to meander on the flood plain.depositionnec kof land na rrowsErosion Page | 28400Geography 312/1,312/2-Intense lateral erosion takes place on the outer bank(concave) forming a bluff.-Deposition takes place on the inner bank (convex)-The land between the two concave banks is narrowedalluriall / depositsOx-bow lakeRiver-The two concave banks join causing the river to take ashort cut.-The cuts are completely off the rest of the river forminga meander cut off called ox-bow lake.d) i) River braids are network of diverging and converting shallow channels along a river course.ii) Describing four processes through which a river transports its load.-Suspension light and insoluble materials are transportedas they float on the surface of water-Saltation- medium sizes/large load are bounced andmoved by water in series of hops and jump-Solution- load is dissolved in water and transporteddownstream.-Traction- heavy load like boulders are dragged androlled along the river bed by hydraulic action or force of gravity8.a) Natural vegetation- is the plant cover that exists on itsown in an area without the interference of external modifying influences like people and animals.b) i) types of grasslands in the following countries

iron-Calcium carbonate/gysum present-Made up of hard pan (laterite)-Soils are prismatic/columnar-Is a zone of illuviation / zone of enrichment?-Soil is generally dark in colour.c) Explaining how the following helps in maintenance of soil fertility and quality.-Crop rotation - growing of different types of crops onthe same piece of land prevent soil exhaustion since different crops require different nutrients from the soil hence soil fertility is improved.-Mixed farming - keeping of animals and growing ofcrops in the same piece of land improves the fertility of the soil. this is because manure from animals is used to enrich the soil with minerals.-Bush fallowing - when land is cultivated for some timeand left to rest for a given period it improves the quality of soil in that of the land regains its fertility during a period of rest.d)State five uses of soil to human activities.-Soils are used in building and construction-Some soil types are used as raw materials for

the geosyncline farmingtwo plates)DiagramText 6 marksTotal 10marksthick layers- The weight of the sediments causes subsidence of the geosyncline leading to accumulation of more sediment -Further subsidence of the geosyncline triggers offcompressional forces which draw the higher grounds closer- As a result the sediments are compressed and form folds which are also thrust upwards to form Fold Mountains - The main fold mountains are formed at the edge of the geosyncline due to the closeness of the source of the forces(edgeof4marksd) Explain three negative effects of folding-The rugged nature of some fold mountain landscapeshinder human settlement / agricultural activities-The leeward slope of some Fold Mountains create rainshadow effect which result into aridity discouraging crop

crater atthe top-if the crater is occupied by rain water / melt water /underground water it forms a crater lakec) Name the lakes markedX - BaringoY - RukwaZ - Mobutud)i)Four reasons why some Rift valley lakes have freshwater-some have surface outlets through which excess saltsdeposits are carried away-some have subterranean outlets which drain the saltsthat accumulate in the lake bed-the lakes have regular inflow of fresh water from riverswhich dilutes the salts keeping the water fresh -some are situated in areas of low temperature thus lowrate of evaporation-some are situated in areas of high rainfall which keepsthe water fresh any 4 x 1 = 4mksii)Three negative effects of human activities on lakes-defforestation exposes soil which is eroded and carriedout into the lake causing siltation-defforestation destroys catchment areas which reduceswater fed into the lakes by rivers-industrialization - establishment of industries has led todisposal of waste / pollution / contamination of lakes -establishment of industries has led to increased wateruse which has lowered water levels in lakes -emergence of water weeds has chocked the lakeshindering effective exploitation of lake resources -emergence of water weeds has hindered transport inlakes-when the weeds rot they affect the habitat of aquatic life10.a)i)Two soil forming processes-weathering processes-decomposition of organic matter-leachingii)State three characteristics of zonal order soils- it has well developed soil profile A - D- found on gently sloping areas- have good drainage / are

in the soil-soil water dissolves minerals in the soil to formsolutions which are easily absorbed by plants-water facilitate transfer of mineral salts from horizon Ato lower horizons / leaching-plants absorb soil water through roots keeping the stemsstrong-soil water supplies water for the living organisms in thesoil-soil water regulate temperature of the soil-water in the soil accelerate chemical weathering-excess water causes water logging in the soil inhibitingsurvival of micro-organisms which causesdecomposition any 3 x 1 = 3mksii)Explain how the following factors influence soilformationClimate-climate influences the rate of weathering,decomposition and leaching-the rate of physical and chemical weathering is faster inhot and wet climate-formation of soil through decomposition of organicmatter is faster in hot and humid climates than in cool and dry climate-high rainfall and warm temperature encourage growthof vegetation which provide plant remains needed for formation of humus-cold climate lowers the action of bacteria hence slowingsoil development-high temperature lead to high evaporation(salinization) leading to the formatio of a hard pan of salt-rainfall lead to formation of alluvial soils througherosion and deposition-wind erosion exposes parent rock to weathering / leadto development of thin soils / wind transport anddeposit soil particles to other areas forming new soils (loess)-rainfall affect the rate at which leaching take place in asoil profileTime-where soil formation processes takes a short durationthe soil are generally immature / where the soils formation processes has taken a long period of time soils are generally well developed / mature c) The diagram below shows a soil arrangementABCDi)The soil

Give two examples of softwood trees grown in Kenya - Juniper / Kenya cedar- podo- pine- cypress- bamboob) Explain how the following factors influence the distribution of natural forests in Kenyai) Temperature- colder climate have lower number of tree species that are capable of surviving- in areas with temperatures above 21oC together with along rainy season tropical rain forest dominate - where temperatures are low with short rainy seasons, coniferous trees are dominant- many trees thrive temperatures between 10oC and 35oC ii) How altitude influence forest distribution- tree growth is limited to altitudes below 3500m because above this temperatures are very low- the types of trees growing at different heights vary / at lower levels of tropical mountains there are tropical rain forests which give way to coniferous forests and then bamboo forests- the forest zone is fond at the mid altitude because it is wetter 2 x 1 = 2mksiii) Influence of human activities on forest distribution -people clear forests for fuel to farm, mine, settle,construct roads and for recreation activities -chemicals used in farming eliminate certain trees that arealready established-use of

(2 marks) Weathering is disintegration /breaking down and decomposition of rocks in situ due to exposure on the surface while mass wasting is down slope movement of weathered material under influence of gravity?? (2mks) ii) Explain two ways in which plants cause weathering.(4 marks)-Pressure of expanding roots in cracks causes rocks to disintegrate - Plants like algae release organic acids on rocks causing its delay - Linchens, mosses maintains rocks moisture which facilitates chemical weathering. b) Explain five ways in which soil creep occurs. (10 marks) -Due to temperature changes, soil particles expand and contract hence shift position down slope - Moisture /rain water cause soil to become wet and compact. On drying the particles loosen and shift position down slope. -Moisture acts as lubricant to soil particles causing their movement down slope - Removal of soil on the downhill side makes the rest of soil to shift down slope - Human activities/Action of borrowing animals may cause the removal of soil on lower part of slope. This triggers soil particles on the upper part of the slope to shift down slope. - Freezing of soil water expands the space between soil particles. Once water thaws, particles fall by gravity shifting down slope. - External forces eg moving trigger effect which causes downwards movement of soil particles. c) i) List four secondary sources of information they are likely to use as they prepare for the study.

(8 mks) -Cutting down of trees/deforestation exposes the soil to agents of erosion -Continuous ploughing weakens the soil structure making it easy for agents of erosion to carry it away. - Ploughing across the contours/up and down the slope creates channels which encourages easy removal of soil by running water agent. - Overstocking leads to trampling on the top soil by animals making them easy to carry away. - Overgrazing leads to removal of vegetation cover thus exposing soil to agents of erosion. - Continuous burning/cultivation without replenishing soil nutrients deprives the soil of the fertility which binds the particles together. This makes soil susceptible to erosion. -Road construction/quarrying/mining loosens the soil making them easily eroded. - Monoculture/over cropping leads to soil exhaustion thus making the soil vulnerable. Shifting cultivation/bush furrowing may leave land unprotected against agents of erosion. -Cultivation of crops in marginal areas loosens the soil especially during dry seasons resulting to wind erosion.
