Question 4 Report
In Nigeria, which of the following vegetation zones is best known for timber exploitation?
Answer Details
The vegetation zone in Nigeria that is best known for timber exploitation is the rain forest. The rain forest is a vegetation zone characterized by a dense growth of tall trees and high rainfall, which is conducive to the growth of large trees suitable for timber production. This type of vegetation is found in the southern part of Nigeria, particularly in states such as Cross River, Akwa Ibom, Rivers, and Delta. In these areas, there are many timber companies that engage in the logging and processing of timber from the rain forest. The timber industry is an important sector of the Nigerian economy, as timber is used for a variety of purposes such as construction, furniture making, and paper production. However, it is important to note that unsustainable logging practices can lead to deforestation and habitat loss, which can have negative impacts on biodiversity and the ecosystem. Therefore, it is important to ensure that logging activities are carried out in a sustainable manner, with measures taken to preserve the forest and its biodiversity for future generations.
Question 5 Report
Which of the following is an effect of the earth's revolution?
Answer Details
One effect of the earth's revolution is that it determines a year. The earth takes approximately 365.24 days to complete one orbit around the sun, which is known as a year. As the earth moves around the sun, it also causes changes in the amount of sunlight that different parts of the planet receive, which in turn affects the seasons. The tilt of the earth's axis also plays a role in determining the seasons. As the earth moves in its orbit, different parts of the planet are tilted towards or away from the sun, which causes the variations in the amount of daylight and darkness we experience throughout the year. Therefore, while day and night, dawn and twilight, and apparent sunrise and sunset are also effects of the earth's rotation, the revolution primarily determines a year.

The following are the importance of highland in Nigeria except
Answer Details
The importance of highlands in Nigeria does not include being a source of minerals. Highlands are elevated areas of land that are generally located at higher altitudes than the surrounding areas. In Nigeria, there are several highland areas, including the Jos Plateau and the Mambilla Plateau. These highlands have several important features and benefits. One of the key benefits of highlands is that they occupy good land that is suitable for agriculture. The higher altitudes often mean cooler temperatures, which can be beneficial for certain crops. Additionally, the soil in highland areas may be richer and more fertile, which can result in higher crop yields. Highlands can also serve as settlement sites, as they are often more defensible than lowland areas. Historically, many highland areas in Nigeria have been used as sites for forts and other defensive structures. Another important feature of highlands is that they are often the source of rivers. The high elevations allow for the accumulation of water, which can then flow downhill and form rivers and other bodies of water. These rivers can be important sources of water for irrigation, as well as for domestic and industrial use. While highlands may contain minerals, they are not typically a major source of mineral resources in Nigeria. Mineral resources in Nigeria are more commonly found in other areas, such as the Niger Delta and the Jos Plateau. In summary, highlands in Nigeria are important for their suitability for agriculture, their historical use as settlement sites, and their role as sources of rivers. While they may contain minerals, this is not typically their primary importance.

Question 14 Report
In the desert region the most prominent agent of erosion is
Answer Details
In the desert region, the most prominent agent of erosion is wind. The wind in the desert can pick up sand and other loose materials and carry them across the landscape, which can cause erosion over time. As the wind blows across the desert, it can pick up loose sand and other sediments and transport them from one location to another. This process, known as "deflation," can cause the erosion of the desert surface over time. In addition, the wind can also cause abrasion, which occurs when sand particles are carried by the wind and collide with other surfaces, such as rocks or other sediments. This can wear away the surface of the rocks or other materials over time, leading to erosion. Overall, wind erosion is a very important process in the desert environment and plays a significant role in shaping the landscape over time.
Question 15 Report
One of the following surveying instruments is used to set out lines at right angles to the main chain line
Answer Details
The surveying instrument used to set out lines at right angles to the main chain line is an optical square. An optical square is a simple, yet precise surveying instrument that consists of two mirrors that are set at exactly 90 degrees to each other. It is used to establish perpendicular lines or right angles to the main chain line during the surveying process. The instrument is set up by placing it on the ground with one mirror facing down the main chain line and the other mirror facing at right angles to the main chain line. To use the optical square, a surveyor would first set up the main chain line using a steel band or another measuring instrument. Once the main chain line has been established, the optical square is set up and aligned with the main chain line. The mirror facing down the main chain line reflects the view of the surveyor along the line, while the other mirror reflects the view at right angles to the main chain line. This allows the surveyor to set out lines at right angles to the main chain line with a high degree of accuracy. In summary, the optical square is a surveying instrument used to set out lines at right angles to the main chain line by reflecting views along the main chain line and at right angles to it.
Question 16 Report
Which of the following is not a factor that favours industrial concentration in Western Nigeria?
Answer Details
Creativity of people in the area is not a factor that favours industrial concentration in Western Nigeria. Industrial concentration refers to the clustering of industries in a particular geographic location. There are several factors that can influence the concentration of industries in an area. In the case of Western Nigeria, three key factors that favour industrial concentration are the availability of raw materials, closeness to major importing and exporting ports, and a good road network. The availability of raw materials is a major factor that influences the location of industries. Industries require access to raw materials to produce goods and services, and if these raw materials are readily available in a particular area, it makes sense for industries to cluster there. Closeness to major importing and exporting ports is also an important factor that can influence industrial concentration. If industries are located close to major ports, they have easier access to the global market and can more easily import raw materials and export finished products. A good road network is also important for industrial concentration. If an area has good roads, it is easier for goods and services to be transported in and out of the area. This can help to reduce transportation costs and increase efficiency, which can be especially important for industries that rely on just-in-time manufacturing and delivery. Creativity of people in the area, while important in terms of innovation and entrepreneurship, is not a direct factor that influences industrial concentration. Other factors such as access to capital, labour force availability, and government policies may play a more important role in promoting industrial concentration. In summary, the availability of raw materials, closeness to major ports, and a good road network are important factors that favour industrial concentration in Western Nigeria. Creativity of people in the area, while important for innovation and entrepreneurship, is not a direct factor that influences industrial concentration.

Which of the following is a way of controlling soil erosion
Answer Details
Contour ploughing is a way of controlling soil erosion. Soil erosion is the process of the removal of topsoil by agents such as wind or water. When the topsoil is removed, it leads to the loss of important nutrients and organic matter that are necessary for plant growth. Soil erosion also leads to the degradation of the soil structure, making it difficult for plants to grow. Contour ploughing involves ploughing furrows along the contours of a slope rather than up and down. This helps to slow down the runoff of water and reduce soil erosion. By ploughing along the contour, the furrows act as a barrier that traps water and allows it to soak into the soil. This helps to improve the water-holding capacity of the soil, which is essential for plant growth. In summary, contour ploughing is an effective way of controlling soil erosion because it helps to slow down the runoff of water and reduce soil loss.
Question 21 Report
In a combined maximum and minimum thermometer, the difference between the hottest and coldest daily temperature for that day gives the
Answer Details
The difference between the hottest and coldest daily temperature for a particular day is called the diurnal range of temperature. A combined maximum and minimum thermometer records both the highest and lowest temperatures that occur during a given period, typically a day. The highest temperature recorded is the maximum daily temperature, and the lowest temperature recorded is the minimum daily temperature. The diurnal range of temperature is the difference between these two values, indicating how much the temperature fluctuated over the course of the day. For example, if the highest temperature recorded was 30 degrees Celsius and the lowest temperature recorded was 15 degrees Celsius, then the diurnal range of temperature for that day would be 15 degrees Celsius.

Answer Details
On maps, lines drawn to join all places in the ocean having equal degree of salinity are called isohalines. Isohalines are similar to contour lines on topographic maps that join all points of equal elevation. However, instead of elevation, isohalines connect all points on a map that have the same salinity in the ocean. Ocean salinity is a measure of the amount of salt dissolved in a given amount of seawater. The salinity of ocean water varies depending on several factors, such as temperature, evaporation, and precipitation. By drawing isohalines on maps, scientists can visualize the patterns of salinity distribution in the ocean and study how it changes over time. The term "isohaline" comes from the Greek word "iso" meaning equal and "haline" meaning salt, so it literally means "equal salt."

Which of the following farming activity best describes the rearing of only animals like cattle, sheep and goat mainly in the savanna belt of the north?
Answer Details
Pastoral farming best describes the rearing of only animals like cattle, sheep, and goat mainly in the savanna belt of the north. Pastoral farming is a type of agricultural activity that involves the rearing of domesticated animals, such as cattle, sheep, and goats, in an extensive system, where the animals are allowed to roam freely over large areas of land. Pastoral farming is often practiced in regions with large areas of grassland, such as the savanna belt in the north of Nigeria, where the animals are able to find enough food and water to sustain themselves. Intensive farming, on the other hand, is a type of agricultural activity that involves the intensive use of inputs, such as land, labor, and capital, to maximize production. Intensive farming is often practiced in regions with high population densities and limited land resources. Animal farming is a general term that can refer to any type of farming that involves the rearing of animals, including both pastoral and intensive farming. Mixed farming is a type of agricultural activity that involves the simultaneous production of crops and livestock, often on the same piece of land.

Question 33 Report
If the scale of two maps are (a;1:100,000 and b;1:400,000) what is the ground distance if the distance between two towns on the maps is 10cm
Answer Details
To determine the ground distance between the two towns on the map, we need to use the scale of the map. The scale tells us how many units of distance on the map (in this case, centimeters) correspond to one unit of ground distance (in this case, kilometers). For map a with a scale of 1:100,000, 1 centimeter on the map represents 100,000 centimeters or 1 kilometer on the ground. Therefore, 10 centimeters on the map represents 10 x 1 kilometer = 10 kilometers on the ground. For map b with a scale of 1:400,000, 1 centimeter on the map represents 400,000 centimeters or 4 kilometers on the ground. Therefore, 10 centimeters on the map represents 10 x 4 kilometers = 40 kilometers on the ground. So the correct answer is 10km, 40km.
