Question 1 Report
Through which of the following processes does solar energy warm the earth;s surface?
Answer Details
Solar energy warms the Earth's surface through the process of radiation. The sun emits electromagnetic waves, including visible light, which travel through space and reach the Earth. When these waves strike the Earth's surface, they are absorbed and converted into heat energy, which warms the air and the ground. This process of heat transfer from one object to another without physical contact is known as radiation. So, the correct option is "Radiation".
Question 2 Report
Which factor of industrial location explains the establishment of cement industries near areas of limestone deposit? Proximity to
Answer Details
The factor of industrial location that explains the establishment of cement industries near areas of limestone deposit is "source of raw materials." Limestone is the primary raw material used in cement production, and it is necessary for the cement industry to be located close to limestone deposits to minimize transportation costs and ensure a consistent supply of raw materials. Therefore, proximity to the source of raw materials is a crucial factor in industrial location decisions for cement industries.
Question 3 Report
The process by which rocks are disintegrated by physical and chemical means in situ is known as
Answer Details
The correct answer is "weathering." Weathering is the process by which rocks are broken down and disintegrated into smaller pieces due to physical and chemical means in their original location or "in situ." Physical weathering includes the breakdown of rocks through mechanical forces such as temperature changes, wind, water, and plant roots. Chemical weathering, on the other hand, involves chemical reactions that alter the chemical composition of the rocks. Together, these processes contribute to the continuous breakdown of rocks, eventually leading to the formation of soil.
Question 4 Report
Which of the following climatic types has the smallest annual range of temperature?
Answer Details
Question 5 Report
The name of the volcanic rock which often forms the root of fold mountains is called
Answer Details
The name of the volcanic rock which often forms the root of fold mountains is called a "Batholith". A batholith is a large mass of intrusive igneous rock formed from cooled magma deep in the earth's crust. When the batholith pushes up towards the surface, it may encounter and cause the overlying rock layers to fold and uplift, resulting in the formation of fold mountains. Batholiths are typically made up of granite, a coarse-grained igneous rock composed mainly of feldspar, quartz, and mica.
Question 6 Report
Through what process are rift valleys formed?
Answer Details
Rift valleys are formed through the process of faulting. Faulting occurs when there is tensional stress in the Earth's crust, causing it to crack and split apart. The split forms two separate blocks of crust, with one side moving downwards and the other side moving upwards, creating a steep-sided valley in between. This process is often associated with the movement of tectonic plates, where the plates move apart and create a rift zone in the Earth's crust. Over time, erosion and other geological processes may modify the shape of the rift valley, but the initial formation is due to faulting.
Question 7 Report
The horizontal displacement of blocks of the earth's crust along a fault plane is called
Answer Details
Question 8 Report
Which of the following vegetation belts in Africa is the most extensive?
Answer Details
The most extensive vegetation belt in Africa is the Savannah. Savannah is a grassland with scattered trees that are typically found in tropical and subtropical regions. It covers a large portion of the African continent, stretching from the west coast of Senegal and Mauritania to the east coast of Ethiopia, and from the south of the Sahara desert to the north of the Kalahari desert. The Savannah vegetation belt is extensive because it is adapted to the climate of the region. The climate in Africa is generally warm and dry, with a long dry season and a short rainy season. The Savannah biome has adapted to these conditions by developing deep roots to access water, and by being able to survive long periods without rainfall. The Savannah biome is also home to a diverse range of wildlife, including large grazing animals such as zebras and giraffes, as well as predators such as lions and cheetahs. This diversity of wildlife is due to the abundance of food that is available in the Savannah, which is in turn supported by the grasses and trees that make up the biome. Overall, the Savannah biome is the most extensive vegetation belt in Africa due to its adaptability to the climate, its ability to support a diverse range of wildlife, and its importance as a source of food and livelihood for many people in the region.
Question 9 Report
Which of the following elements of weather and climate is matched with the wrong measuring instrument?
Answer Details
Humidity and barometer are matched with the wrong measuring instrument. A barometer is used to measure atmospheric pressure, while humidity is measured using a hygrometer. Humidity refers to the amount of moisture present in the air, and it is usually expressed as relative humidity. A hygrometer measures the amount of water vapor in the air to calculate the relative humidity. On the other hand, a wind vane is used to measure the direction of the wind, while a thermometer is used to measure temperature. A raingauge is used to measure the amount of rainfall in a particular area. These instruments are correctly matched with their respective elements of weather and climate.
Question 10 Report
What pollution is caused by all the following except
Answer Details
Treated sewage, industrial waste, oil spillage, and fishing with chemicals are all sources of pollution. The question is asking which one of the options does not cause pollution. The answer is treated sewage. Treated sewage refers to the wastewater that has undergone a treatment process to remove pollutants and contaminants before being discharged into the environment. While untreated sewage can cause pollution, treated sewage is not considered a significant source of pollution as the treatment process removes most of the pollutants.
Question 11 Report
Which of the following planets is the farthest from the sun in the solar system?
Answer Details
Question 12 Report
What is the approximate distance between two places if one is located on 11oN and the other on 5oS on the same longitude?
Answer Details
To calculate the distance between two places on the same longitude, we need to find the length of the arc of the Earth's circumference between the two latitudes. The Earth's circumference is approximately 40,000 km. Therefore, each degree of latitude represents approximately 40,000 km/360 = 111.11 km. The distance between 11°N and 5°S is equal to the sum of the distance between the equator and 11°N plus the distance between the equator and 5°S. The distance between the equator and 11°N is 11° x 111.11 km/degree = 1,222.21 km. The distance between the equator and 5°S is 5° x 111.11 km/degree = 555.55 km. Therefore, the total distance between the two places is 1,222.21 km + 555.55 km = 1,777.76 km. Therefore, the answer is closest to 1,776 km.
Question 13 Report
Favourable factors for lumbering in Africa include all the following except
Answer Details
The question is asking to identify the exception among the listed factors that are favorable for lumbering in Africa. The first three options all suggest reasons why lumbering in Africa might be favorable - high demand for tropical timber, presence of many economic trees, and high demand for fuelwood. These factors suggest that there is a market for lumber products, and that there are abundant resources available for harvesting. The last option, "inaccessible equatorial forest," is the exception. This suggests that there are challenges to accessing and harvesting lumber from the equatorial forest, which could make lumbering less favorable in these areas. Factors that could contribute to inaccessibility might include terrain, climate, or other environmental factors. Therefore, the correct answer is "inaccessible equatorial forest," as it is the only factor that does not contribute to favorable conditions for lumbering in Africa.
Question 14 Report
Which of the is the first stage in the process of lumbering?
Answer Details
The first stage in the process of lumbering is the identification of suitable species of trees. This involves the selection of trees that have the desired characteristics such as straight trunks, appropriate diameter and height, and wood quality. It is important to identify the right species of trees to ensure that the lumber produced is of high quality and meets the needs of the market. Once the suitable species of trees are identified, the process of felling the trees can begin.

Answer Details
Metamorphic rocks are rocks that have undergone a transformation due to heat, pressure, and/or chemical activity. Based on the given options, the examples of metamorphic rocks are gneiss and quartzite. Basalt and gabbro are examples of igneous rocks while granite and gabbro are a combination of igneous and intrusive rocks. Gneiss and basalt are a combination of metamorphic and igneous rocks.
Question 17 Report
What factor accounts for the slow rate of industrial development in Tropical Africa?
Answer Details
One of the factors that account for the slow rate of industrial development in Tropical Africa is the inadequate capital. Capital is the money and resources needed to start and sustain a business, and without it, industrial development cannot happen at a significant pace. Inadequate capital can prevent businesses from investing in modern equipment and technology, hiring skilled labor, and expanding their operations. Furthermore, inadequate capital can also prevent businesses from accessing the resources they need to grow, such as loans and investment capital. Thus, without adequate capital, the growth and development of industries in Tropical Africa can be significantly hindered.
Question 18 Report
What is the name of the local wind that blows in West Africa between November and February?
Answer Details
The local wind that blows in West Africa between November and February is called the Harmattan. Harmattan is a dry and dusty northeasterly trade wind that blows from the Sahara Desert across West Africa towards the Gulf of Guinea. The wind is usually cold and can cause the temperature to drop significantly. It also carries a lot of dust and sand, which can reduce visibility and cause respiratory problems for people and animals. The Harmattan wind is an important weather phenomenon in West Africa, and its arrival is often eagerly anticipated for its cooling effect on the region.
Question 19 Report
Which of the following are circular depressions formed on the bed of a river in its upper course by pebbles carried by the river?
Answer Details
Question 20 Report
African rivers exhibit the following characteristics except
Answer Details
African rivers exhibit all of the following characteristics except for "that they have great depths." Most African rivers have their sources in the interior highlands and flow towards the coast or interior basins. Due to the topography of the land, many African rivers have rapids and waterfalls on their courses. African rivers also exhibit seasonal variations in water volume, with some rivers experiencing a very high volume of water during the wet season and a very low volume of water during the dry season. However, African rivers are not known for their great depths. In general, African rivers are shallow and wide, with the exception of a few deep gorges and canyons. This is partly because the rivers have a relatively low gradient and slow velocity, which limits their ability to erode the river bed and deepen the channel.
Question 21 Report
The number of persons per square kilometer of land is called
Answer Details
Population density is the number of individuals in a particular area, usually expressed as the number of persons per square kilometer of land. It is a measure of the concentration of people living in a given area and helps to provide insight into how crowded or sparsely populated a region is. A high population density suggests that there are many people living in a relatively small area, while a low population density indicates that the area has fewer people living in it.
Question 22 Report
Which of the following is the most important weathering process in Karst regions?
Answer Details
The most important weathering process in Karst regions is carbonation. Karst regions are areas that are characterized by soluble rocks such as limestone, dolomite, and gypsum. Carbonation occurs when carbon dioxide in the atmosphere dissolves in rainwater, forming carbonic acid. This carbonic acid reacts with the soluble rocks, causing them to dissolve and form sinkholes, caves, and other distinctive landforms commonly found in Karst regions. Hydrolysis is the chemical breakdown of minerals by water, oxidation involves the combination of minerals with oxygen, and hydration is the process of minerals absorbing water molecules. While these processes can contribute to weathering in Karst regions, carbonation is considered to be the most important process due to the prevalence of soluble rocks in these areas.
Question 23 Report
The release of harmful substances into the environment is called
Answer Details
The correct answer is "pollution". Pollution refers to the introduction of harmful substances into the environment that cause negative effects on living organisms and their surroundings. This can be caused by human activities such as industrialization, transportation, and improper waste disposal. Pollution can take different forms such as air pollution, water pollution, and soil pollution. Examples of harmful substances that cause pollution include carbon monoxide, lead, and nitrogen oxides, among others. Pollution has negative effects on the environment, human health, and the economy, and efforts are made to reduce and prevent it.
Question 24 Report
Which of the following is the most important agent of erosion in humid regions?
Answer Details
Question 26 Report
Which of the following is a disadvantage of high population density?
Answer Details
A disadvantage of high population density is unemployment. When there is a high population density, there are more people competing for limited resources, such as jobs. This leads to a high rate of unemployment, as the number of people seeking employment is higher than the available job opportunities. This can lead to poverty, social unrest, and a strain on the economy. High population density can also lead to increased pressure on social amenities, such as water supply, housing, and transportation, which can further exacerbate the problem of unemployment.
Question 27 Report
What method of mining is used for extracting petroleum in Africa?
Answer Details
Petroleum, also known as crude oil, is extracted from the earth's surface through a method called drilling. This method involves drilling deep wells into the earth's surface to reach the layer of rock that contains the oil reserves. Once the well reaches the oil reservoir, the oil is pumped out using various techniques, such as pressure or suction. Drilling is the primary method used for extracting petroleum in Africa, as it is in most other regions of the world where oil reserves are found. Other methods such as crushing, adit, or open cast are not suitable for extracting petroleum as it is usually located deep underground and requires specialized equipment and techniques to extract it.

Question 29 Report
What will be the local time in Nigeria 15oE when the time is 7.00 p.m. in town Y 30oW?
Answer Details
To solve this problem, we need to know the time difference between the two locations. Since Nigeria is 15 degrees east of the Prime Meridian (0 degrees), and town Y is 30 degrees west of the Prime Meridian, we can calculate the time difference as follows: 15 degrees east x 4 minutes/degree = 60 minutes (or 1 hour) ahead of GMT 30 degrees west x 4 minutes/degree = 120 minutes (or 2 hours) behind GMT So, the time difference between the two locations is 3 hours (2 hours + 1 hour). If it is 7.00 p.m. in town Y (30oW), then we need to add 3 hours to get the local time in Nigeria (15oE). 7.00 p.m. + 3 hours = 10.00 p.m. Therefore, the local time in Nigeria (15oE) when the time is 7.00 p.m. in town Y (30oW) is 10.00 p.m.

Which of the following towns has winter rainfall and summer drought?
Answer Details
Question 31 Report
Which of the following modes of transportation provides door-to-door services?
Answer Details
Road transport provides door-to-door services. This is because road transport can reach almost any location, including remote areas and neighborhoods, and can deliver goods or people directly to their final destination. On the other hand, rail transport, ocean transport, and air transport typically require additional modes of transportation, such as trucks or buses, to reach their final destination. Therefore, among the given options, road transport is the only mode that provides door-to-door services.
Question 32 Report
Which of the following is a feature commonly found in the youthful stage of a river?
Answer Details
The youthful stage of a river is characterized by its erosive activity and its attempt to establish its course. As a result, one feature commonly found in this stage is interlocking spurs. These are ridges of land that project into the river valley and are gradually eroded away as the river flows. Interlocking spurs are formed because the river is not yet powerful enough to cut through them, so it has to wind its way around them, creating a zigzag pattern.

Answer Details
Hail, fog, dew, and frost are all forms of precipitation. Precipitation is any form of water that falls from the atmosphere and reaches the ground. This includes rain, snow, sleet, hail, dew, and frost. Hail is formed when frozen water droplets are lifted by strong updrafts in thunderstorms, while fog is formed when water vapor in the air condenses close to the ground. Dew forms when moisture condenses on cool surfaces, and frost forms when the temperature drops below freezing and water vapor in the air freezes directly onto surfaces.
Question 37 Report
Most warm ocean currents flow
Answer Details
Most warm ocean currents flow from the Equator. This is because the equator receives more solar radiation than other regions, which leads to warming of the seawater. As a result, the seawater becomes less dense and rises to the surface. The rising warm water then flows away from the equator in the form of ocean currents. These currents carry heat from the equatorial region to other parts of the world, affecting the climate and weather patterns in those regions.
