Awọn alaye Idahun
A device for transferring information from an analogue map into a computer for further manipulation is called a Digitizer. A digitizer is a piece of hardware that is used to convert analogue information into a digital format that can be read and manipulated by a computer. In the case of maps, a digitizer is used to trace the features on a paper map and convert them into a digital format, such as a shapefile or a georeferenced image. This allows the information on the map to be easily manipulated, stored, and analyzed using computer software. An aerial photograph is a type of image that is taken from the air, often from an airplane or drone, and is used to capture information about the land and features on the ground. A global positioning system (GPS) is a network of satellites and receivers that is used to determine the location, speed, and direction of an object on the Earth's surface. A plotter is a type of printer that is used to produce large-format images, such as maps, technical drawings, and architectural plans.

Which of the following is an effect of the earth's revolution?
Awọn alaye Idahun
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.

Awọn alaye Idahun
A line joining all points of equal salinity is an isohaline. In simpler terms, salinity refers to the amount of salt in water, and an isohaline is a line on a map that connects all the points in a body of water that have the same level of salinity. So, if you were to take a water sample at each point along an isohaline, you would find that they all have the same amount of salt in them. Isohalines are important in oceanography and marine biology because changes in salinity can affect the behavior and distribution of marine organisms, as well as ocean currents and other physical processes.

Awọn alaye Idahun
A settlement located where two rivers meet is called a confluence town. A confluence is a point where two or more rivers meet and flow together as one. Settlements located at confluences are called confluence towns because they are situated at a unique and strategic location where two rivers meet. Confluence towns have historically been important for transportation, trade, and agriculture, as well as for strategic and military reasons. They are often located at the intersection of major river systems, making them important hubs for transportation and commerce. The availability of water from two rivers can also make confluence towns ideal locations for farming and irrigation. Therefore, a settlement located where two rivers meet is called a confluence town.

The following are volcanic mountains except
Awọn alaye Idahun
Monadnock of the USA is not a volcanic mountain. Volcanic mountains are formed when molten rock (magma) rises to the surface and erupts, building up layer upon layer of solidified rock and ash. Some examples of well-known volcanic mountains include Cotopaxi in Ecuador, Mount Fuji in Japan, and Mount Merapi in Sumatra. Monadnock, on the other hand, is a type of mountain called a monadnock or inselberg, which means "island mountain." These are isolated hills or mountains that rise abruptly from surrounding flat or gently sloping terrain and are often made of hard, resistant rock that has not been worn away by erosion. Monadnock is a monadnock and was formed through the uplift of a large mass of rock and the subsequent erosion of the surrounding land.

If the scale of a map is 2cm to 1km, what is the ground distance if the distance between two towns on the map is 20cm
Awọn alaye Idahun
If the scale of a map is 2cm to 1km, it means that for every 2 centimeters on the map, there is a real-world distance of 1 kilometer. To find the ground distance between two towns on the map, we need to convert the distance on the map into a real-world distance. If the distance between the two towns on the map is 20cm, we can start by calculating how many kilometers it represents in the real world. Since the scale is 2cm to 1km, we can divide the distance on the map by 2 to get the real-world distance: 20 cm / 2 = 10 km Therefore, the ground distance between the two towns is 10 kilometers. So the answer is: 10km.

Which of the following is an importance of the atmosphere to living organisms?
Awọn alaye Idahun
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.

In Nigeria, which of the following vegetation zones is best known for timber exploitation?
Awọn alaye Idahun
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.

Awọn alaye Idahun
Out of the given options, storms are not a landform producing agent. Landforms are natural features on the Earth's surface, such as mountains, valleys, and plains, that are created over long periods of time through the actions of various agents. These agents include natural forces such as water, wind, ice, and gravity. Waves, rivers, and glaciers are all agents that can shape the Earth's surface over time. Waves can erode coastlines and create features like sea cliffs and sea caves. Rivers can carve out valleys and canyons through erosion and transport sediment downstream. Glaciers can also erode and transport sediment, as well as create features such as moraines and U-shaped valleys. On the other hand, storms are not an agent that shapes the Earth's surface in a significant way. Storms are short-lived weather events that can cause erosion and deposition in some areas, but they are not powerful enough to create significant landforms on their own. However, storms can interact with other landforming agents like rivers and waves, exacerbating their effects and creating more dramatic changes to the landscape.

Which of the following towns is not a precolonial town
Awọn alaye Idahun
Enugu is not a precolonial town. Precolonial refers to the time period before the colonization of a particular area or region by European powers. In Nigeria, many towns and cities existed before the arrival of the Europeans, and these are referred to as precolonial towns. Ilorin, Bida, and Ibadan are all precolonial towns in Nigeria. They existed as independent kingdoms and city-states with their own unique cultures, traditions, and forms of governance long before the arrival of the Europeans. Enugu, on the other hand, was not a precolonial town. The town was founded in the early 20th century by the British colonial authorities as a coal mining settlement. While there were some settlements and villages in the area before the arrival of the British, Enugu did not exist as a town or city with a defined political and social structure until it was established by the colonial authorities.

The following are the importance of highland in Nigeria except
Awọn alaye Idahun
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.

Awọn alaye Idahun
The best solution to the rapid depletion of forest resources in West Africa is to introduce forest conservation techniques. This approach involves implementing sustainable practices that protect the natural environment and enable communities to benefit from the forest resources without damaging them. It includes measures such as reducing deforestation, promoting reforestation, and enforcing laws against illegal logging and other harmful activities. Reserving hectares of land for plantations may not be a sustainable solution, as it can lead to monoculture and may not provide the same benefits as natural forests. Importing wood from other countries may exacerbate the problem, as it encourages overconsumption and does not address the underlying issues of deforestation. Employing more forest guards can help deter illegal activities, but it may not be enough without also implementing conservation techniques. Therefore, implementing forest conservation techniques is the best solution as it promotes the sustainable use of forest resources while protecting the natural environment and supporting local communities.

Which of the following is a way of controlling soil erosion
Awọn alaye Idahun
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.

Which of the following is a reason for the high volume of trade between Nigeria and developed countries?
Awọn alaye Idahun
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.

Awọn alaye Idahun
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.
