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 major percentage of the world's exports of citrus fruits comes from the Mediterranean region. The Mediterranean region, which includes countries such as Spain, Italy, Greece, and Turkey, has a warm and sunny climate that is ideal for growing citrus fruits such as oranges, lemons, and grapefruits. These fruits are widely cultivated in the region, and a large portion of the production is exported to other countries. This region has long been known for its fertile soils and favorable growing conditions, making it one of the major citrus-producing areas in the world. In addition, the Mediterranean region has a long history of citrus cultivation and a strong tradition of producing high-quality fruit. So, while citrus fruits can be grown in other regions such as the tropical and cool temperate regions, the Mediterranean region remains the largest exporter of these fruits.

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
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."

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
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.

Which of the following is not a factor that favours industrial concentration in Western Nigeria?
Awọn alaye Idahun
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.

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.

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.

Awọn alaye Idahun
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.

Awọn alaye Idahun
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.
