# Question Ans
21.

Use the diagram below to answer the question that follows:
The textual class that can hold the greatest amount of moisture is

A. sand

B. sand loam

C. clay loam

D. clay

D

22.

Which of the following is not most suitable in chain survey?

A. irregular slopes

B. rocky environments

C. embarkment areas

D. plain topography

Detailed Solution

answer is D, all other options are wrong because they are not too suitable for chain survey to their land forms(topography)
Plain topography is the most suitable in chain survey because in chain survey, the only instruments required are a pair of compass and a scale rule. On the plain topography there is no bend or contour which makes the setting of compass easy and chain throwing not be stressful
23.

Which of the following belongs to the upper course of river.

A. Ox-bow lake

B. Meander

C. V-shaped valley

D. Artificial embankment

Detailed Solution

V-shaped valley is formed as a result of vertical erosion of a river which makes it deeper with step sides because the water as active in following
Ox-blow lakes are crescent-shaped lakes formed by running water flowing through a meander neck. It is formed at the lower course of a river
Meanders are found at the middle course of a river network
Artificial embankment is a long artificial mound of stone or earth, built to hold back water
24.

The world has different time zone because

A. most countries do not agree on having the same time zone

B. it is a major way of differentiating countries from each other

C. the sum does not shine on the earth surface at the same time

D. the variation in weather and climate will not allow countries to have the same time zone

Detailed Solution

the sun does not shine on the earth surface at the same time. the earth spin on its axis, every 24 hours , the earth makes a complete rotation on its axis each rotation is called a day as the earth rotate different part of the earth receive sunlight and darkness
25.

One of the following properties of soil can be easily observed in the field

A. Fertility

B. Texture

C. Permeablity

D. Acidity

Detailed Solution

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
26.

High clouds is made up of

A. stratus

B. cirrus

C. altostratus

D. alto cummullus

Detailed Solution

Cirrus make up the high cloud and it is composed of ice-crystals, white and wispy. High clouds are cloud whose highest is between 6,000 m to 12,000m above the earth surface.

Stratus is one of the layers that make up the low cloud, altostratus is composed of water droplets partially covering the sky and it is also a part of middle cloud

Alto cumullus is also a distinct part of the middle cloud characterized by water droplets in layers with flattered bases in lines.

The high cloud is made up of three distinct parts which are cirrus, cirrocumulus, cirrostratus
27.

One of the following instruments is used in measuring the direction of wind

A. Cup anenometer

B. barometer

C. wind anenometer

D. wind vane

Detailed Solution

Cup anenometer is an instrument used for measuring the direction of the speed of wind

Barometer is used to measure air pressure and predicting changes in the weather

Wind vane is used to indicate the direction of the wind.
28.

Use the map below to answer the question that follows:
The area marked E is good for the cultivation of

A. cottons

B. millet

C. groundnut

D. raffia palm

Detailed Solution

The area marked E on the map of Nigeria is Kano state and Kano is known for its cultivation of groundnut it is the groundnut most producing state in Nigeria
29.

One of the reasons of rapid growth of world population is

A. improved social and medical facilities

B. stable government

C. rainfall and its reliability

D. agricultural system practised

Detailed Solution

The provision of modern and improved medical and social facilities to area tends to attract more population concentration to another.
Other options are wrong because the government being stable does not determine population growth, social amenities provided by the government is the only factor that can make the population growth low, either rainfall or not, people will migrate and reproduce.
The agricultural system practical in an area also does not determine rapid population growth. Either mono-cropping or mixed farming is practiced population will always grow.
30.

The export trade of Mali is based mainly on

A. groundnuts

B. cotton

C. cattle

D. cocoa

B
