Question 1 Report
A manager o f pulp and paper factory would prefer wood from?
Answer Details
A manager of a pulp and paper factory would prefer wood from "spruce". Spruce trees have long, straight trunks that are ideal for producing high-quality pulp and paper products. Spruce trees also have a relatively high yield of pulp compared to other tree species, meaning that more pulp can be produced from a given volume of wood. Additionally, spruce wood has relatively low levels of extractives, which are natural chemicals found in wood that can interfere with the production of high-quality paper. While other tree species like ebony, teak, and mahogany have desirable characteristics for furniture making and other decorative uses, they are not commonly used in the production of pulp and paper products due to their limited availability and high cost.
Question 2 Report
The tropical maritime and the tropical continental air masses in Nigeria are responsible for the?
Answer Details
The tropical maritime and tropical continental air masses in Nigeria are responsible for the alternating wet and dry seasons in the country. Air masses are large bodies of air with similar temperature and humidity characteristics. The tropical maritime air mass originates over the Atlantic Ocean and brings warm, moist air to Nigeria, while the tropical continental air mass originates over the Sahara Desert and brings hot, dry air to Nigeria. During the wet season, the tropical maritime air mass dominates, bringing moist air to Nigeria, which leads to heavy rainfall and increased humidity. During the dry season, the tropical continental air mass dominates, bringing hot and dry air, which leads to low humidity and little to no rainfall. Therefore, the alternating wet and dry seasons in Nigeria are a result of the interplay between the tropical maritime and tropical continental air masses.
Question 3 Report
The two most important factors which account for the pattern of population distribution in West Africa are?
Answer Details
The two most important factors which account for the pattern of population distribution in West Africa are "favourable physical conditions and human inertia". Favourable physical conditions refer to areas with fertile soils, adequate water supply, and a suitable climate for agriculture, which attracts people to settle in those areas. In West Africa, the coastal regions, river valleys, and areas with a high rainfall, such as the Guinea Coast and the Niger Delta, have more favorable physical conditions and therefore have higher population densities. Human inertia refers to the tendency for people to remain in a location, even if conditions are not favorable, due to factors such as cultural ties, family connections, and lack of resources to move elsewhere. This can lead to the clustering of populations in certain areas, even if those areas do not have the most favorable physical conditions. Overall, the combination of favorable physical conditions and human inertia explains the pattern of population distribution in West Africa, with higher population densities in areas with more favorable physical conditions and a clustering of populations due to human inertia.
Question 6 Report
The main aim of constructing the railway systems in West Africa was to?
Answer Details
The main aim of constructing the railway systems in West Africa was to evacuate raw materials and minerals for export. The railway systems were constructed during the colonial era to facilitate the transportation of natural resources from the hinterland to the coastal ports for export to Europe. The resources that were transported included minerals such as gold, tin, and diamonds, as well as agricultural products such as cocoa, palm oil, and groundnuts. The railway systems were also used to transport goods and people between the different towns and cities in the region. While the railway systems did link different areas of the region, their primary purpose was to facilitate the export of natural resources.
Question 7 Report
The direction of flow of ocean currents is determined mainly by the?
Answer Details
The direction of flow of ocean currents is mainly determined by the prevailing winds and the rotation of the earth. The winds and the rotation of the earth combine to create a pattern of surface currents in the oceans, known as the "ocean conveyor belt." The conveyor belt is a system of currents that move water around the globe, transporting heat from the tropics to the poles and helping to regulate the Earth's climate. The salinity of the ocean and the amount of freshwater inflow can also affect ocean currents, but they are not the main factors that determine their direction of flow. The rotation of the earth and land and sea breezes can influence local currents, but they do not play a significant role in determining the overall flow of ocean currents. Similarly, the shape of the continental and the temperature of the continental interior do not have a direct impact on the direction of ocean currents.
Question 8 Report
An example of mechanically formed sedimentary rock is?
Answer Details
An example of a mechanically formed sedimentary rock is conglomerate. Conglomerate is a type of sedimentary rock that is made up of large, rounded clasts (fragments) of rock that have been cemented together. These clasts are often several centimeters in diameter and are typically made up of a variety of different rock types. Conglomerate forms when these clasts are deposited by a river or other flowing body of water and then cemented together over time by minerals such as silica or calcium carbonate. Other examples of mechanically formed sedimentary rocks include sandstone and shale. In contrast, chemically formed sedimentary rocks, such as chalk and dolomite, are formed by precipitation from water that is saturated with dissolved minerals. Coal, on the other hand, is an organic sedimentary rock that forms from the remains of plants that have been compressed and altered over time.
Question 9 Report
Many important ancient settlements in the Middle East developed as a result of the?
Answer Details
Many important ancient settlements in the Middle East developed as a result of the emergence of important trading routes. The Middle East has been an important crossroads of trade and commerce for thousands of years, connecting Europe, Africa, and Asia. Ancient civilizations in the region developed along major trade routes, such as the Silk Road, that facilitated the exchange of goods, ideas, and culture. These routes linked major cities and settlements, allowing for the growth of trade and commerce, and the development of urban centers. As a result, many of the most important ancient settlements in the Middle East, such as Babylon and Petra, were located at key points along these trade routes.
Question 10 Report
The carbon cycle is more prevalent in the?
Answer Details
The carbon cycle is more prevalent in the atmosphere. The carbon cycle refers to the movement of carbon between living organisms, the atmosphere, and the Earth's crust. Carbon is exchanged between these different parts of the Earth's system through a series of natural processes, including photosynthesis, respiration, and decomposition. While carbon is found in all parts of the Earth's system, the largest reservoir of carbon is the atmosphere, where carbon dioxide (CO2) is present in the air. This is why the carbon cycle is more prevalent in the atmosphere. Carbon moves between the atmosphere and other parts of the Earth's system through processes such as the uptake of CO2 by plants during photosynthesis, the release of CO2 by respiration, and the transfer of carbon from the atmosphere to the oceans through dissolution.

Answer Details
Question 12 Report
The process of mountain -building by either folding or block faulting is known as?
Answer Details
The process of mountain-building by either folding or block faulting is known as "orogenesis". This term refers to the geological processes that lead to the formation of mountain ranges over millions of years. Folding occurs when rocks are bent and deformed under pressure, creating folds in the earth's crust that can eventually form mountain ranges. Block faulting, on the other hand, occurs when large blocks of rock are pushed up or down along a fault line, also leading to the formation of mountains. Both of these processes are part of orogenesis, which can be influenced by a variety of factors, including tectonic activity, volcanic eruptions, and erosion. Mountain ranges created through orogenesis can have a significant impact on the landscape, climate, and ecology of the surrounding areas.

Answer Details
Question 18 Report
Which of the following minerals is likely to be absent in a region consisting mainly of igneous and metamorphic rocks?
Answer Details
Coal is likely to be absent in a region consisting mainly of igneous and metamorphic rocks. This is because coal is a sedimentary rock that forms from the accumulation of organic material in swampy environments over millions of years. Igneous rocks are formed from the solidification of molten rock, while metamorphic rocks are formed from the transformation of existing rocks due to heat and pressure. Neither of these processes involves the accumulation of organic material necessary for coal formation. Therefore, it is unlikely to find coal deposits in areas dominated by igneous and metamorphic rocks.

This means that these regions have the highest amount of goods and services that are imported and exported in the world. Western Europe is known for its strong economy and is a major hub for international trade, while the U.S.A is the world's largest economy and a major player in global trade. The trade between these regions involves a wide range of products, including raw materials, manufactured goods, and services.
Question 21 Report
Which of the following is a type of iron ore?
Answer Details
The type of iron ore is "Limonite". Limonite is a common iron ore that is brownish-yellow or yellowish-brown in color, and is mainly composed of iron oxide and hydroxide minerals. It often forms in bogs, wetlands, and shallow marine environments. Limonite is not as widely used for iron production as other types of iron ore such as hematite and magnetite, but it can still be an important source of iron. It is often found in association with other minerals such as clay, sand, and gravel, and is typically mined using open-pit mining methods. Overall, limonite is an important resource for iron production, and is also used in other applications such as pigments, soil conditioner, and in the construction industry.

The rapid growth of cities like Tokyo, Osaka and Yokohama in Japan can be attributed to?
Answer Details
The rapid growth of cities like Tokyo, Osaka, and Yokohama in Japan can be attributed to large-scale industrialization. After World War II, Japan experienced a period of rapid economic growth and industrialization, which led to the concentration of industry and jobs in urban areas. This resulted in a significant increase in population, as people moved from rural areas to cities in search of employment opportunities. Tokyo, Osaka, and Yokohama are all major industrial centers in Japan, and their growth was fueled by the expansion of manufacturing and other industries. As a result, these cities have become some of the largest and most populous in the world.
