Maelezo ya Majibu
The type of water left in the soil after excess water has been drained off following heavy rainfall is known as field capacity. Field capacity refers to the amount of water that the soil can hold after excess water has drained away and the soil particles have become saturated. This water is held in the soil by a combination of gravity and the attraction between water molecules and soil particles. In other words, field capacity is the point at which the soil is neither too wet nor too dry, and it is the maximum amount of water that can be stored in the soil and still be available for plants to use.

Which of the following is not a factor that favours industrial concentration in Western Nigeria?
Maelezo ya Majibu
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 reason for the high volume of trade between Nigeria and developed countries?
Maelezo ya Majibu
The correct answer is "Colonial ties." One of the primary reasons for the high volume of trade between Nigeria and developed countries is the historical and economic ties that Nigeria shares with many of these nations. Nigeria was a British colony until it gained independence in 1960, and as a result, it has maintained strong trade relationships with the UK and other former British colonies. These relationships have been fostered over many years through cultural, social, and economic ties. In addition, many developed countries have invested heavily in Nigeria's natural resources, such as oil, which has further strengthened the trade relationships between Nigeria and these countries. This has led to the development of a large export market for Nigerian products, such as crude oil and natural gas. Therefore, the correct answer is "Colonial ties," as it has been a significant reason for the high volume of trade between Nigeria and developed countries.

Maelezo ya Majibu
River regime is best described as the seasonal variation in the volume of water in a river. It refers to the pattern of the flow of water in a river over the course of a year, which is affected by changes in temperature, precipitation, and other factors. The river regime describes the variations in the discharge, or the amount of water flowing in the river, over time. This variation can be influenced by several factors, such as the amount and timing of rainfall, the amount of snowmelt, and the presence of dams or other structures that regulate the flow of the river. In some regions, rivers have a well-defined regime with distinct seasons of high and low water, while in other regions, the regime may be less predictable due to more erratic weather patterns. Understanding the river regime is important for managing water resources, predicting floods, and maintaining ecosystems that depend on the natural flow of rivers.

Which of the following is an effect of the earth's revolution?
Maelezo ya Majibu
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.

Which of the following is not caused by the earth's rotation?
Maelezo ya Majibu
Seasonal changes are not caused by the earth's rotation. The earth's rotation is responsible for causing day and night, as the rotation of the earth on its axis causes the sun to appear to rise and set each day. It is also responsible for the deflection of winds and ocean currents. Seasonal changes, on the other hand, are caused by the tilt of the earth's axis as it revolves around the sun. The earth's axis is tilted at an angle of approximately 23.5 degrees, which causes different parts of the earth to receive different amounts of solar radiation as the earth orbits the sun. This results in the changes in temperature and weather patterns that we experience as the seasons. In summary, seasonal changes are not caused by the earth's rotation, but rather by the earth's tilt as it orbits the sun. The earth's rotation, however, does cause day and night and the deflection of winds and ocean currents.

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?
Maelezo ya Majibu
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.

Maelezo ya Majibu
Cement factories are usually located near sources of raw materials. Raw materials such as limestone, clay, shale, and other minerals are used to produce cement. These materials are usually found in abundance in certain geological formations or deposits. Transporting these raw materials over long distances can be costly and time-consuming, so it makes sense for cement factories to be located as close as possible to the sources of these materials. This helps to keep production costs low and ensures a steady supply of raw materials for the factory. Additionally, being close to the raw materials can also help to reduce the environmental impact of the factory. If the raw materials have to be transported over long distances, this can lead to increased emissions from transportation vehicles, which can contribute to air pollution and climate change. Therefore, to ensure the efficient and sustainable production of cement, it is common for cement factories to be located near sources of raw materials.

Maelezo ya Majibu
Geo-referencing in GIS is the process of assigning spatial locations (coordinates) to a dataset, such as an image, map, or survey data, so that it can be viewed, analyzed, and compared with other spatial datasets. The main objective of geo-referencing is to integrate datasets from different sources that have different coordinate systems, projections, and scales into a common reference framework. This enables users to overlay, compare, and analyze different spatial datasets accurately and effectively. Geo-referencing involves aligning the data to a known reference system, such as a map or satellite imagery, and assigning a spatial location to each data point. This process involves identifying control points, which are specific locations that appear in both the data and the reference system, and using them to determine the transformation that is needed to align the data with the reference system. Once the data has been geo-referenced, it can be used for data acquisition, data management, manipulation, and analysis in GIS. Geo-referenced datasets can be used for a wide range of applications, including natural resource management, urban planning, environmental monitoring, and disaster management.

Maelezo ya Majibu
An example of a coastline of emergence is a raised beach. A coastline of emergence refers to a type of coastline that is formed when the land is rising relative to the sea level. This can be caused by tectonic activity or changes in the level of the land due to the melting of glaciers. When the land rises, the sea level falls, which exposes the previously submerged shoreline. This results in the formation of a raised beach, which is a distinctive feature of a coastline of emergence. A raised beach is a beach that is located above the current sea level, and it is typically characterized by a flat or gently sloping surface. Other features of a coastline of emergence may include sea cliffs, wave-cut platforms, and marine terraces. These features are formed by the erosion of the land by the sea when it was at a higher level, followed by the uplift of the land. An example of a coastline of emergence can be found along the coast of Norway. The Norwegian coastline has experienced significant uplift due to tectonic activity, which has resulted in the formation of raised beaches, sea cliffs, and marine terraces. In summary, a coastline of emergence is a type of coastline that is formed when the land rises relative to the sea level. One of the distinctive features of this type of coastline is a raised beach, which is a beach that is located above the current sea level. An example of a coastline of emergence can be found along the coast of Norway.

Maelezo ya Majibu
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.

Which of the following is an importance of the atmosphere to living organisms?
Maelezo ya Majibu
The importance of the atmosphere to living organisms is that it provides oxygen for animals and plants for respiration. The atmosphere is the layer of gases that surrounds the Earth, and it plays a vital role in supporting life on the planet. One of the most important functions of the atmosphere is that it provides oxygen, which is necessary for the respiration of animals and plants. During the process of respiration, living organisms take in oxygen and use it to convert food into energy. This process is essential for the survival of all living things, and it cannot occur without oxygen. Additionally, plants use the process of photosynthesis to produce oxygen, which is then released into the atmosphere for animals to breathe. In addition to providing oxygen, the atmosphere also plays a role in regulating the Earth's temperature and protecting living organisms from harmful solar radiation. The atmosphere also provides a medium for weather patterns to form, which are important for the distribution of water and other resources that support life. Therefore, it can be concluded that the most important function of the atmosphere to living organisms is providing oxygen for respiration.

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
Maelezo ya Majibu
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.

Which of the following is a way of controlling soil erosion
Maelezo ya Majibu
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.

In Nigeria, which of the following vegetation zones is best known for timber exploitation?
Maelezo ya Majibu
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.

Maelezo ya Majibu
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.
