Question 2 Report

Which of the following is the most effective agent of coastal erosion?

sea current

sea waves

underground water

sea tides

Answer Details

Sea waves are the most effective agent of coastal erosion. This is because waves carry a lot of energy and force, which can cause rocks and other materials on the coast to break down over time. As waves approach the shore, they slow down and become taller, causing them to crash onto the beach with more force. This force can cause erosion by breaking down rocks and carrying sediment away from the coast. Sea currents, underground water, and sea tides can also contribute to coastal erosion, but waves are generally considered to be the most significant factor.

Question 7 Report

The dynamic and interdependent complex interaction of soil,climate and vegetation with its animal population is called

food chain

ecosystem

carbon cycle

hydrological cycle

Answer Details

The answer to this question is ecosystem. An ecosystem is a community of living organisms and their physical environment, which includes both biotic (living) and abiotic (non-living) components. The components of an ecosystem, such as the soil, climate, vegetation, and animal population, are all interdependent and interact with each other in a dynamic way. For example, the vegetation in an ecosystem provides food and habitat for the animal population, which in turn helps to pollinate and disperse seeds, thus maintaining the growth and diversity of the vegetation. The climate and soil type also affect the type of vegetation that can grow in an ecosystem, which then affects the animal population that can live there. Overall, an ecosystem is a complex and interconnected web of relationships between living and non-living components that work together to sustain life.

Question 11 Report

Which of the following is not a common farming system in West Africa?

crop rotation

rotational bush fallowing

terracing

subsisitence

Answer Details

The answer is terracing. Terracing is not a common farming system in West Africa. Crop rotation, rotational bush fallowing, and subsistence farming are common farming systems in West Africa. Crop rotation involves planting different crops in the same field in different seasons to maintain soil fertility and control pests and diseases. Rotational bush fallowing is a farming system where a plot of land is cleared of vegetation and farmed for a few years, and then allowed to lie fallow for a longer period to allow the vegetation to regenerate. Subsistence farming is a type of farming where farmers produce only enough food to feed themselves and their families. It is a common farming system in West Africa, where small-scale farmers grow crops and rear animals for their own consumption. Terracing, on the other hand, is a farming practice where steps are constructed on sloping land to create a flat surface for farming. It is more commonly used in mountainous regions such as Asia and South America, where there is a need to farm on steep slopes.

Question 12 Report

Light industries predominate in West Africa because of

inadequate capital

sparse population

adequate technology

adequate power supply

Answer Details

Light industries predominate in West Africa because of inadequate capital. This is because light industries require less capital and technology to set up and operate compared to heavy industries. The economies of West African countries are largely based on agriculture, which does not generate much income, leading to limited investment capital. Therefore, entrepreneurs in West Africa tend to start small-scale industries that require less capital, such as textile mills, food processing plants, and furniture making. These industries also provide employment opportunities for the rapidly growing population, making them a viable option for economic growth. However, the limited capital also affects the quality and quantity of output as well as the competitiveness of the industries.

discharge of gasses from factories

volcanic cruptions

Answer Details

Air pollution is the contamination of the air with harmful substances that affect human health and the natural environment. Evapo-transpiration is a natural process that involves the evaporation of water from the soil and the transpiration of water vapor from plants into the atmosphere, which does not cause air pollution. On the other hand, the fumes from motor vehicles, the discharge of gases from factories, and volcanic eruptions can release harmful substances such as carbon monoxide, sulfur dioxide, and nitrogen oxides into the air, causing air pollution. Therefore, the answer is evapo-transpiration.

In areas where folding has occurred, oil and natural gas usually collect in

synclines

horst

nappes

Answer Details

In areas where folding has occurred, oil and natural gas usually collect in synclines. Synclines are trough-like folds in the Earth's crust where the beds dip towards each other. As sediments accumulate in these troughs, they can form reservoirs where hydrocarbons such as oil and natural gas can collect and accumulate. The hydrocarbons are trapped by impermeable rock layers, such as shale or salt, that prevent them from escaping to the surface. Therefore, synclines are often targeted for oil and gas exploration and drilling.

warm wind

Answer Details

Descending wind does not encourage the formation of rainfall. Descending air warms adiabatically (without exchange of heat with the surrounding), leading to an increase in temperature and a decrease in relative humidity. This results in a reduction of cloud formation, leading to clear skies and dry weather. Therefore, option C, descending wind, does not encourage the formation of rainfall.

Question 27 Report

Possible solution to the problem of soil erosion in the highlands of West Africa include all the following except

indiscriminate felling of trees

rotational grazing

strip cultivation

planting of shelter belts

Answer Details

Soil erosion is a major problem in the highlands of West Africa due to factors such as deforestation, overgrazing, and unsuitable agricultural practices. The options listed in the question provide possible solutions to the problem of soil erosion except for one. Option A, "indiscriminate felling of trees," involves cutting down trees without considering their impact on soil conservation. This practice increases the rate of soil erosion and is, therefore, not a solution to the problem. Option B, "rotational grazing," involves dividing a large pasture into smaller areas and rotating the grazing of livestock between these areas. This helps to prevent overgrazing, reduces soil compaction, and allows grass to grow back. Option C, "strip cultivation," involves planting crops in strips or rows and leaving spaces between them. This method reduces soil erosion by allowing rainfall to infiltrate the soil instead of running off. Option D, "planting of shelter belts," involves planting trees or shrubs around farmlands to provide protection against wind and water erosion. This helps to stabilize the soil, reduce runoff, and provide habitat for wildlife. Therefore, the answer is option A, "indiscriminate felling of trees," as it exacerbates soil erosion rather than solving it.

Question 28 Report

Which of the following does not encourage the formation of rainfall?

converging wind

ascending wind

descending wind

warm wind

Answer Details

Descending wind does not encourage the formation of rainfall. When air descends, it warms up and becomes drier because its ability to hold moisture increases with temperature. This warm, dry air evaporates moisture from the ground, plants, and other sources, leading to arid conditions. Therefore, descending wind does not lead to the formation of clouds and rainfall, but rather clear, sunny weather. On the other hand, converging and ascending winds bring moist air together and upward, leading to cloud formation and eventually precipitation. Warm winds also contribute to the formation of rainfall by bringing warm, moist air to cooler regions where it can condense and form clouds.

Question 31 Report

Desert areas experience high daily range of temperature because

they are generally low-lying

the sky is cloudless

they experience very high atmospheric pressure

the winds blow off-shore at night

Answer Details

Desert areas experience high daily range of temperature mainly because the sky is cloudless. Clouds play an important role in regulating temperature because they reflect some of the incoming solar radiation back into space and trap some of the outgoing heat radiation from the earth's surface. In the absence of clouds, the earth's surface receives a lot of solar radiation during the day, which causes the temperature to rise. At night, the earth's surface loses heat radiation rapidly, which causes the temperature to drop. Therefore, in desert areas where there are no clouds to regulate the temperature, there is a high daily range of temperature, with very hot days and very cold nights.
