3.
Seasons are determine in the tropical areas by
.
A. transportation
B. rainfall
C. evaporation
D. temperature
Explanation.
Tropical areas are the areas of the world that are near the equator where the weather is very warm. Temperature determines season in the tropics.
Transpiration is the passage of water or vapor from a living body through a membrane or pores
Rainfall is the amount of rain that falls on a particular area, since the tropic is predominantly temperate, rainfall has no impact in determining seasons there
Evaporation is about converting liquid to vapor. It is just a process and a determinant factor in season determination

A. Glaciation
B. Abrasion
C. Attrition
D. Deflation
Explanation.
Glaciation is a term that has to do with ice Glacier itself is a large accumulation of frozen sea or river or ice.
Abrasion - here, small rock particles are hurles by wind against rock surfaces.
Attrition is a process by which rock particles rub against each other and wear away.
Deflation occurs when wind blows away rock wastes and in doing, lowers the desert surface thereby producing depressions.
Winds involve movement of particles when they blow, glaciation is often static and that makes it right answer.

It is noon in place X, what is the time in a place 45oE
.
A. 1:00 PM
B. 3:00 AM
C. 3:00 PM
D. 1:00 PM
Explanation.
360o makes a circle, earths single rotation takes 24 hours, 360o divided by 24 hours gives 15o. So in 1 hour, the earth covers 15o. Therefore 45o equals 3 hours. In time calculation when you move eastern you gain (addition). The question says noon. SO we move eastwards and gain 15o = 1 hour, 45o = 3 hours, being noon. We gain so three hours place noon equals 3 pm

One of the following properties of soil can be easily observed in the field
.
A. Fertility
B. Texture
C. Permeablity

Texture has to do with feeling and touching. One can get to know if a soil sample is smooth or coarse by touching.
Testing a soil sample fertility can only be done at the laboratory with equipment, the same goes with testing of soil acidic properties.

Soil permeability involves introduction of liquid to know if the particular soil can retain water or not. It might be stressful as particular soil can retain water or not. It might be stressful as movement to get the liquid may be required unlike checking soil texture by just bending to the ground to prick and feel with the hand

Barchan is a crescent - shaped shafting sand dunes, loess is an unstratified brown barry deposited by wind while self dunes are sand dunes in the form of a long narrow ridge
Yardang as to do with erosional land forms.

33.
The flow of a river at the lower course is slow because
.
A. thick vegetation cover affects free flow of water
B. of the increase in human activities
C. the gradient is greatly reduced
D. of the increase in the volume of water
Explanation.
Answer C is the gradient greatly reduced when water flow down from the upper course it flows with a high velocity downwards. An example is a waterfall.as the water enter the lower course the gradient( the rate of regular ascent or descent) is reduced because the slope of the bed is gentle and also, materials washed down from the upper course are deposited there. the vegetation cover does not determine water movement as rivers are not vegetative. tress can only cover the surrounding areas and not the river itself Human activities and water volume also does not determine the flow of river at the lower course. water either small or mass will always find its way

A wave is a continuous movement on water surface, usually in the ocean. Its is also said to be a moving ridge on the surface of the water.

Option A, ripples often occur on the surface of small liquids or a small body of water

Option B, currents is a continuous movements of water in one direction. When there is water erosion, the eroded water tends to move in a particular direction, that is an example of a current.

Tsunamis is a large oceanic wave caused by an earthquake under the sea. The question says circulatory movement of surface water which is continuous in the ocean, current, ripples and tsunamis are wrong as they do not fit as the right answer.

A woman living on Longitude 30oE is carrying her body to the hospital around 1 am on Monday. Calling her husband on plane who is on 30oW, when will the husband pick the call
.
A. 3:00 AM
B. 5:00 PM
C. 7:00 AM
D. 9:00 PM
Explanation.
30oE + 30oW = 60o, 1hour = 15o, therefore 60o gives 4 hours which means both are 4 hours interval. In time calculation, the west love an hour at every step which the est gains an hour. The wife is carrying the baby and calling the husband at 30oE, 1 am, so the husband at the west will loose an hour at every step.
1 am before 12 midnight, westward minus 3 hours gives 9 pm in Sunday. Therefore, the wife calls on Monday while the husband receives the call on Sunday at 9 pm.

Guinea savanna

B.

high forest

C.

sahel savanna

D.

sudan savanna

Explanation.
Answer is D, The Nigeria savanna vegetation include Sudan,Sahel and guinea.

Sudan savanna comes immediately after the north of the guinea savanna as the cardinal point on the diagram describes the direction to the north, the Sudan comes after the guinea the chief product are cattle, groundnut, guinea corn and millet The Sahel savanna is made up of grasses and water shortage is experienced there and this does not encourage plant to grow luxuriantly.

The guinea savanna is suitable between Sudan savanna and rain forest

The chronological order of these mining activities is
.
A. exploitation, exploration, refining, transportation
B. transportation, refining, exploitation, exploration
C. exploration, exploiration, refining, transportation
D. refining, exploitation, transportation, exploration
Explanation.
The answer is c exploration,exploitation, refining and transportation chronological order deals with arrangement in order of time from the earliest to the latest in mining exploration which is about inquiring and studying the mineral to be mined comes first, followed by exploitation which deals with working/getting the mineral. refining comes after which is just about separating the minerals and removing unwanted material from it. transporting of the ruined minerals to another site then comes afterwards Option A is wrong because you don't work on minerals if you don't discover and study it first that explain exploitation coming before exploration Option B is wrong because transportation cannot come first in mining process due to the fact that mining hasn't been done so there is nothing mined to transport Option D is wrong because one needs to exploit the minerals to be mined before separating the minerals which refining stand for

49.
Deforestation occurs when one of the following happens except
.
A. trees are cut down for agricultural purpose
B. trees are cut down for limber
C. bush is subjected to excessive burning and grazing
D. shifting cultivation is practised
Explanation.
Shifting cultivation occurs when a piece of land is left fallow for a while, mostly within a farming season for cultivation to be done on another piece of land. That has no damaging effect on the forest.
When trees are cut down for agricultural purposes, timber production and during excessive bush burning and grazing, the forest is often lost or reduced as there will be reduction in the numbers of trees available.
This often lead to erosion and desert enroachment
