Question 1 Report
Abrasion,attrition and deflation are processes of
Answer Details
Abrasion, attrition, and deflation are processes of wind erosion. Abrasion is the process by which wind carries small rock particles that strike and scrape against rocks, breaking them apart. Attrition is the process by which these small rock particles collide with each other, breaking into even smaller particles. Deflation is the process by which wind removes and carries away loose particles, such as sand or dust, leaving behind a surface that is more compact and solid. Together, these processes can erode and shape landscapes in arid regions with little vegetation cover, such as deserts.

Answer Details
Pastoral nomadism is a type of subsistence agriculture that involves raising livestock, such as cattle, sheep, and goats, by constantly moving from one place to another in search of food and water for their animals. This practice is common in arid and semi-arid regions of the world, where there is limited rainfall and vegetation. In West Africa's savanna areas, pastoral nomadism is predominantly practiced by the Fulani people, who are known for their long-distance cattle herding and transhumance practices, where they move their animals seasonally in search of greener pastures.

Question 6 Report
A feature formed from the solidification of highly fluid basic lava on the earth's surface is known as a
Answer Details
The feature formed from the solidification of highly fluid basic lava on the earth's surface is known as a "basalt plateau." A basalt plateau is a large area of flat, elevated land that is formed by the accumulation of layers of basaltic lava flows. These lava flows are usually highly fluid and can cover vast areas of land. As they cool and solidify, they form a thick layer of basalt rock that can be several hundred meters thick. Over time, erosion can remove the overlying rock and expose the basalt plateau. Basalt plateaus are common in volcanic regions and are found all over the world.

Question 9 Report
The low level of trade among African countries is due to
Answer Details
The low level of trade among African countries is primarily due to the similarity of products they produce. Many African countries are reliant on the production of primary commodities, such as raw materials and agricultural products, and have a limited industrial base. This means that they often produce similar products, which reduces the need for them to trade with each other. Additionally, poor infrastructure, including transportation systems and communication networks, and trade barriers such as tariffs, import quotas, and bureaucratic red tape, also hinder trade among African countries. The high demand for home-made products and liberalization of trade are not major factors contributing to the low level of trade among African countries.
Question 10 Report

Answer Details
Sheet erosion tends to be more serious than other forms of erosion because it involves more widespread removal of soil from the land surface. Unlike other forms of erosion that remove soil from specific points, sheet erosion removes the topsoil and exposes the subsoil. The subsoil is not suitable for crop production, and the removal of the topsoil leads to soil infertility, which affects agricultural productivity. Additionally, sheet erosion is more difficult to control because it is caused by surface runoff, which is difficult to redirect or control, especially on sloping land.
Question 14 Report

Answer Details
Loamy soils are better for agriculture than other soil types because they retain air, moisture, and humus, which is important for plant growth. The soil texture of loamy soils is such that it allows for a balance of water retention and drainage, making it ideal for plants to absorb water and nutrients while preventing waterlogging. Additionally, loamy soils are rich in mineral nutrients and organic matter, such as humus, which supports the growth of crops. The organic matter in loamy soils provides a source of nutrients for plants and improves the structure of the soil, making it easier for roots to penetrate and access water and nutrients. Therefore, loamy soils are considered the most fertile and productive soil type for agriculture.

Answer Details
An aquifer is a water-bearing rock layer that can store and transmit groundwater. It is usually found between two layers of impermeable rock that prevent the water from seeping out. The permeable rock can be sandstone, limestone, or other types of rock that allow water to flow through their pores and spaces. Aquifers are important sources of water for wells and springs, and they can be replenished by precipitation and surface water that percolates down into the ground.
Question 23 Report
Flooding can be prevented by
Answer Details
Flooding can be prevented by planning towns and cities in such a way that they take into account the possibility of flooding. This can involve building structures on higher ground, creating designated flood plains, and ensuring that drainage systems are properly designed and maintained. Dumping refuse in drainage channels can actually exacerbate flooding by clogging up the system, while building houses and roads in flood plains can put people and property at risk. Building strong fences around buildings does not directly prevent flooding, although it may provide some protection from the effects of flooding such as debris carried by the flood waters.
Question 24 Report
One of the features found in the upper course of a river is
Answer Details
The feature found in the upper course of a river is a gorge. This is a narrow and steep-sided valley that is usually formed as a result of erosion by fast-flowing water over a long period of time. The river in the upper course has a high gradient, and the water flows with greater force and velocity, thus eroding the rock and soil more efficiently. The rocks in the upper course of a river are typically harder, and the river may have to cut through them, forming a narrow and steep-sided valley known as a gorge. Gorges are often characterized by vertical cliffs or near-vertical cliffs, and they may have rapids and waterfalls where the river's gradient is steeper.
Question 25 Report
Inselberg may best be described as
Answer Details
An inselberg is a residual hill with steep sides and usually exposed by denudation. It is a geological landform that stands out conspicuously above the surrounding plain due to its resistance to erosion. Inselbergs are typically composed of hard rocks such as granite, and they are often found in arid or semi-arid regions where weathering is minimal. Therefore, the correct option is: "a residual hill with steep sides and usually exposed by denudation."
Question 26 Report
Fold mountains are basically formed as a result of
Answer Details
Fold mountains are formed as a result of compressional forces. When two tectonic plates collide, the rock layers between them are pushed together and forced upward, causing the crust to fold and buckle. This process is known as orogeny and it results in the formation of fold mountains, such as the Himalayas, the Alps, and the Andes. The compressional forces can also cause the rocks to fracture and fault, leading to the formation of thrust faults and overthrusts. Over millions of years, erosion can wear down the mountains, but the forces that created them can still be seen in their folded and faulted rock layers.

Which of the following is a feature of limestone regions?
Answer Details
Stalagmites are features of limestone regions. Limestone is a sedimentary rock formed from the accumulation of organic and inorganic materials, such as the remains of marine organisms and minerals, over time. It is composed primarily of calcium carbonate. Limestone regions are characterized by karst topography, which is characterized by sinkholes, caverns, and underground drainage systems. Stalagmites are formed in caves as a result of water dripping from the cave ceiling, depositing calcium carbonate on the cave floor over time. The resulting cone-shaped deposit grows upwards from the cave floor, forming a stalagmite.
