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.

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.

Coal is the rock that is organically formed. Coal is formed from the remains of ancient plants and trees that died millions of years ago. Over time, these organic materials were buried under layers of sediment and rock, which subjected them to intense pressure and high temperatures. This process caused the organic matter to transform into coal, a black or brown rock that is primarily composed of carbon. In contrast, Gypsum, Grit, and Shale are all rocks that are formed through inorganic processes. Gypsum is formed from the evaporation of saline water, grit is a sandstone that is formed from the accumulation of sand particles, and shale is formed from the accumulation of mud and silt. In summary, coal is the only rock that is formed through organic processes, while gypsum, grit, and shale are formed through inorganic processes.

Answer Details

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.

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.

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.

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.

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

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.

Urban settlements often supply manufactured goods to rural settlements. Manufactured goods are products that are made using raw materials and processes that transform these materials into finished products. Urban areas often have a higher concentration of factories and industries that produce these manufactured goods, which are then supplied to rural areas. This allows rural residents to access products that they may not be able to produce themselves, such as electronics, household appliances, and other consumer goods. By supplying these goods, urban settlements play an important role in supporting the economic development of rural areas.

Answer Details

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.

The term that fits the given definition is "watershed." A watershed is a highland area that separates the headwaters of rivers that flow in different directions but originate from the same mountainous source. Think of it as a dividing line that determines which direction rainwater will flow. Rain that falls on one side of the watershed will flow into one river, while rain that falls on the other side will flow into a different river. This separation is important because it affects the water quality and quantity of each river, and it can have significant impacts on the ecosystems that depend on those rivers.

Answer Details

The term that is defined as the total surrounding or medium of any organism in a given area is "environment". Environment refers to the sum total of all biotic and abiotic factors that affect an organism in a given area. Biotic components refer to all living organisms in an ecosystem, including plants, animals, fungi, and bacteria. Abiotic components, on the other hand, refer to all non-living factors, such as water, air, sunlight, temperature, soil, and minerals, that affect living organisms. An ecosystem is a community of living organisms, along with their non-living environment, that interact with each other. Therefore, an ecosystem is made up of both biotic and abiotic components, and it is a specific unit of the environment that can be studied as a distinct entity.

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."

Answer Details

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.
