Question 1 Report
Organic components of the soil include all the following except_______
Answer Details
The organic components of the soil include microorganisms, humus, and animal remains. The correct answer, therefore, is "rock pedestal." Rock pedestal, also known as bedrock, is a non-organic component of the soil. It is the solid, underlying layer of rock that makes up the Earth's crust. Bedrock does not contain any organic material, and it does not contribute to the fertility of the soil. On the other hand, the organic components of soil are essential for healthy plant growth. Microorganisms break down organic matter into nutrients that plants can absorb, while humus provides a rich source of nutrients for plant growth. Animal remains, such as dead insects or animal waste, can also provide organic material for the soil. In summary, while microorganisms, humus, and animal remains are all examples of organic components of soil, rock pedestal is a non-organic component and does not contribute to the fertility of the soil.

Question 3 Report
Lines joining places with same mean annual rainfall are called___________
Answer Details
Lines joining places with the same mean annual rainfall are called isohyets. Isohyets are lines drawn on a map connecting points that receive the same amount of rainfall in a year. The word "isohyet" comes from the Greek words "iso" meaning "equal" and "hyetos" meaning "rain". These lines help us understand the patterns and distribution of rainfall over a certain area, and can be useful for various purposes such as agriculture, water management, and meteorology.
Question 4 Report
If the time in New York (75°W) is 5.00pm, The time in Nigeria(15°E) will be
Answer Details
New York (75°W) is 5 hours behind Coordinated Universal Time (UTC-5) and Nigeria (15°E) is 1 hour ahead of Coordinated Universal Time (UTC+1). Therefore, there is a time difference of 6 hours between New York and Nigeria. When it is 5.00pm in New York, we can add 6 hours to find the time in Nigeria: 5.00pm in New York + 6 hours = 11.00pm in Nigeria So the correct answer is 11.00pm.
Question 5 Report
Which of the following rocks is composed of the skeletons of microscopic sea plants and animals?
Answer Details
The rock composed of the skeletons of microscopic sea plants and animals is called "Chalk". Chalk is a soft, white, porous sedimentary rock that is formed from the remains of tiny marine organisms called coccolithophores. These microscopic creatures have hard shells made of calcium carbonate, and when they die, their shells accumulate on the ocean floor. Over time, these accumulations can become compressed and cemented together, forming the soft rock we know as chalk. Chalk is often found in areas that were once covered by shallow seas, such as in the cliffs of southern England. It has many uses, including as a writing surface, in construction, and as a natural fertilizer. Its softness and white color also make it a popular material for art, such as in the creation of chalk drawings.
Question 6 Report
A type of land-form that is associated with large scale orogeny is a
Answer Details
A fold mountain is a type of land-form that is associated with large scale orogeny. In simple terms, orogeny is the process of mountain building, which occurs when two tectonic plates collide and push up the land between them. This process causes the rock layers to bend, fold and become uplifted, creating a fold mountain. Examples of fold mountains include the Rocky Mountains in North America and the Himalayas in Asia.
Question 7 Report
If the distance between two places on a map is 2cm, while the distance on land is 4km, the scale of the map is
Answer Details
The scale of a map is the ratio of the distance on the map to the actual distance on land. It is usually written as a fraction, like 1:100,000, where the first number represents the distance on the map and the second number represents the corresponding distance on land. To find the scale of the map in question, we need to divide the actual distance on land (4km) by the distance on the map (2cm). First, we need to convert 4 km to cm: 4 km = 4 x 10^3 m = 4 x 10^3 x 100 cm = 4 x 10^5 cm Now, we divide the actual distance on land (4 x 10^5 cm) by the distance on the map (2 cm): (4 x 10^5 cm) / (2 cm) = 2 x 10^5 So the scale of the map is 1 : 2 x 10^5, which is equivalent to 1:200,000.
Question 8 Report
The greatest volcanic regions of Africa are found in
Answer Details
The greatest volcanic regions of Africa are found in two main areas: Kenya and Tanzania, and Sudan and Ethiopia. In Kenya and Tanzania, the Great Rift Valley runs through the region and is home to some of the most iconic volcanic features on the continent. The valley is characterized by a series of interconnected volcanoes, hot springs, geysers, and lakes. The most famous volcanic peaks in the area are Mount Kilimanjaro, Mount Kenya, and Mount Meru. In Sudan and Ethiopia, the East African Rift Valley also runs through the region and is another hotspot for volcanic activity. The valley is home to a number of active and dormant volcanoes, including Erta Ale, Nyiragongo, and Mount Karthala. In addition, the region is known for its geothermal activity, with numerous hot springs and geysers dotting the landscape. Both of these regions are characterized by their tectonic activity, with the movement of the Earth's crust leading to the formation of rift valleys, which in turn create the conditions for volcanic activity. The result is a stunning and unique landscape that draws visitors from all over the world.
Question 9 Report

Answer Details
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
Question 10 Report
Lines joining places of equal sunshine duration on maps are__________
Answer Details
The lines joining places of equal sunshine duration on maps are called Isohel. Isohel is a type of contour line that connects all the points on a map that receive the same amount of sunlight in a given period, usually a day or a year. These lines are similar to contour lines on a topographic map that connect points of equal elevation. Isohels are used to show areas with similar amounts of sunshine and can be used to analyze patterns in climate and weather. For example, isohel maps can help identify areas with higher or lower amounts of sunlight and help to plan agriculture, solar power generation, and other activities that depend on sunlight.
Question 11 Report
The peeling off of surface layers of a rounded boulders during mechanical weathering is called________
Answer Details
The peeling off of surface layers of a rounded boulder during mechanical weathering is called exfoliation. Exfoliation is a type of mechanical weathering process that occurs when layers of rock or boulder peel off from the surface due to pressure release. The process usually occurs in rocks that have been exposed to intense heat, pressure, and other environmental factors for a long time. As a result of these factors, the rock expands and contracts repeatedly, causing the surface layers to crack and break apart. Over time, these cracks become wider, and the layers begin to peel off, revealing the smooth and rounded boulder underneath. Exfoliation is often seen in granitic rocks, where the outer layers peel off to form concentric layers resembling an onion. The process can also occur in other rock types such as sandstone and shale. Overall, exfoliation is an important geological process that contributes to the breakdown and erosion of rocks over time, shaping the landscape around us.

Question 14 Report
One of the following does not determine the availability of resources in a country____________
Answer Details
Evolution does not determine the availability of resources in a country. Evolution refers to the gradual changes in species over time through the process of natural selection. It has no direct effect on the availability of resources in a country. Population, emigration, and morbidity, on the other hand, can influence the availability of resources in a country. A large population can lead to increased demand for resources, while emigration can decrease the number of people using those resources. Morbidity, or the rate of illness and disease in a population, can also impact the availability of resources, as a large portion of the population may require medical attention and resources.

Question 21 Report
When the moon comes in between the earth and the sun________
Answer Details
A solar eclipse occurs when the moon comes between the earth and the sun. During a solar eclipse, the moon blocks the sun's light and casts a shadow on the earth. This causes a temporary darkness in the middle of the day and is a spectacular sight to see. Solar eclipses can only happen during a full moon and are relatively rare events. They occur because the moon and the sun are exactly in line with the earth and the moon's shadow falls on the earth.

Question 25 Report
Latitude 66 and half marks the____________
Answer Details
Latitude 66 and a half (66.5) marks the Arctic Circle. The Arctic Circle is an imaginary line that circles the Earth at approximately 66.5 degrees latitude, which is located in the northern hemisphere. This line marks the southernmost point at which the sun can remain continuously above or below the horizon for a full 24 hours, depending on the time of year. Therefore, if you are at a location with latitude 66.5 degrees or higher, it means that you are within the Arctic Circle and can experience the phenomenon of the midnight sun during the summer solstice, where the sun remains above the horizon for a full 24 hours. In contrast, during the winter solstice, the sun will not rise above the horizon at all, resulting in 24 hours of darkness. Hence, the correct answer is: - Arctic Circle
Question 26 Report
A mercury barometer is used for measuring_________
Answer Details
A mercury barometer is used for measuring atmospheric pressure. Atmospheric pressure is the force exerted by the weight of air molecules in the atmosphere. It is an important parameter that affects weather patterns and other natural phenomena. A mercury barometer consists of a long glass tube filled with mercury and inverted into a dish of mercury. The mercury in the tube rises or falls depending on the atmospheric pressure. When the atmospheric pressure is high, the weight of the air above the barometer pushes down on the surface of the mercury in the dish, forcing the mercury in the tube to rise. Conversely, when the atmospheric pressure is low, the weight of the air above the barometer is less, and the mercury in the tube falls. By measuring the height of the mercury column in the tube, the atmospheric pressure can be determined. The standard unit of atmospheric pressure is the Pascal (Pa), but barometric pressure is often measured in units of millimeters of mercury (mmHg) or inches of mercury (inHg). In summary, a mercury barometer is a device used to measure atmospheric pressure by observing the height of a column of mercury in a glass tube.
Question 27 Report
The innermost section of the Earth is the__________
Answer Details
The innermost section of the Earth is the core. The Earth's core is the central part of our planet, located beneath the mantle. It is composed primarily of iron and nickel, and is divided into two distinct layers: the outer core and the inner core. The outer core is a liquid layer that surrounds the solid inner core. The inner core is a solid, dense ball of metal that is about the size of the Moon. The core plays a crucial role in the Earth's magnetic field, which helps protect our planet from harmful solar radiation. The core also generates the heat that drives the movement of the Earth's tectonic plates, which causes earthquakes and volcanic eruptions. Understanding the properties and behavior of the Earth's core is an important area of research in the field of geophysics.

All the following are environmental hazards except___________
Answer Details
The environmental hazard among the given options that is not included is afforestation. Afforestation refers to the process of planting trees in an area where there was no forest, or the forest has been destroyed, and it is typically seen as a positive action for the environment. On the other hand, the other three options are environmental hazards that can have negative impacts on people and the environment. Flooding, for example, can lead to property damage, displacement of people, and loss of life. Vulcanicity, which refers to the movement of magma and volcanic activity, can result in the release of toxic gases, destruction of property, and loss of life. Deforestation, which is the clearing of forests for various human activities, can cause soil erosion, loss of biodiversity, and contribute to climate change.
Question 31 Report
The oldest system of agriculture in Nigeria which now survives only in very remote areas is
Answer Details
The oldest system of agriculture in Nigeria which now survives only in very remote areas is shifting cultivation, also known as slash-and-burn agriculture. Shifting cultivation involves cutting down a patch of forest or woodland, burning the vegetation, and planting crops in the ash-enriched soil. Farmers would use the land for a few years until the soil fertility decreases, then abandon it and move to a new area, leaving the old area to regenerate into forest or woodland. This practice was sustainable when population densities were low and farmers had access to vast areas of land. However, with the growth of population and increased pressure on land, shifting cultivation has become less sustainable, leading to soil degradation, deforestation, and loss of biodiversity. Today, shifting cultivation survives only in very remote areas, where population densities are still low and access to land is not restricted.

Question 33 Report
Which of the following is not a form of mass movement?
Answer Details
The answer is "earthquake" as it is not a form of mass movement. Mass movement refers to the process by which large amounts of soil, rock, and other debris move down a slope under the influence of gravity. Landslides, rockslides, and talus creep are all examples of mass movement. An earthquake, on the other hand, is a sudden shaking of the earth's surface caused by the movement of tectonic plates. While earthquakes can cause landslides and other types of mass movement, the earthquake itself is not a form of mass movement. Instead, it is a geological event that can trigger mass movement in the surrounding area.
Question 34 Report
The feature is one or the land forms associated with_________
Answer Details
The feature associated with river erosion is valleys. River erosion occurs when a river's fast-moving water cuts into its riverbed and banks, causing the river to widen and deepen over time. This process creates steep-sided valleys that are wider at the bottom than at the top. The riverbed and banks are constantly being reshaped by the erosive forces of the water, which carry away sediment and rocks. Over time, the river's course may change as it continues to erode and deposit material, carving new valleys and leaving behind a signature of its past path in the form of terraces.
Question 35 Report
The Farthest planet from the sun in the solar system is_______
Answer Details
The farthest planet from the Sun in the solar system is Pluto. Pluto used to be considered the ninth planet in the solar system, but it was reclassified as a "dwarf planet" in 2006. Pluto's distance from the Sun varies because it has an elliptical orbit, which means that its distance from the Sun changes throughout its orbit. On average, Pluto is about 3.7 billion miles (5.9 billion kilometers) away from the Sun. This makes it much farther from the Sun than any of the eight "traditional" planets in the solar system, including Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. So, to summarize, Pluto is the farthest planet from the Sun in our solar system, even though it's now classified as a dwarf planet.

Question 38 Report
The plains formed when the slopes of mountains are worn back in arid and semi-arid regions my mechanical weathering is called_______
Answer Details
The plains formed when the slopes of mountains are worn back in arid and semi-arid regions by mechanical weathering is called "Pediplains". Pediplains are a type of plain that form as a result of the gradual erosion and weathering of mountains and hills. They typically occur in arid and semi-arid regions where there is little vegetation to protect the land from erosion. Over time, as the wind, rain, and other natural forces wear away at the mountain slopes, sediment is carried downhill and deposited on the surrounding plain. This sediment can be made up of rocks, sand, and soil, and can create a relatively flat and gently sloping plain that extends out from the base of the mountain. Unlike other types of plains, such as alluvial plains or outwash plains, which are formed by water deposition, pediplains are formed by the mechanical weathering and erosion of rock and soil. They are typically found in regions where there is little precipitation and where the climate is dry and hot, which can help to speed up the weathering process.
Question 39 Report
Which of these hazard would most like result directly from deforestation?
Answer Details
Deforestation is the clearing of trees and other vegetation in a forested area. One of the most likely hazards that can result directly from deforestation is soil erosion. When trees are cut down, the roots that held the soil in place are also removed, leaving the soil exposed and vulnerable to erosion by wind and rain. With no tree cover to protect the soil, rainwater can wash away the topsoil, leading to soil erosion. This process can cause the soil to become less fertile, which can make it difficult for plants to grow and can ultimately lead to desertification. Additionally, deforestation can also lead to changes in the water cycle, which can result in decreased water availability, increased flooding, and other forms of water pollution. However, these hazards are less directly linked to deforestation than soil erosion.
Question 40 Report
In which of the following rock types is petroleum mainly found?
Answer Details
Petroleum is mainly found in sedimentary rocks. Sedimentary rocks are formed from the accumulation and cementation of sediments, which can include organic matter such as dead plants and animals. Over time, this organic matter can become buried and subjected to heat and pressure, which can transform it into petroleum through a process called diagenesis. Petroleum is a fossil fuel that is composed of hydrocarbons, which are molecules made up of carbon and hydrogen atoms. The organic matter in sedimentary rocks that forms petroleum is usually derived from marine plants and animals that died and sank to the bottom of the ocean. Over time, these organic remains can be buried by layers of sediment, and the heat and pressure from the overlying rocks can cause them to be transformed into petroleum. While it is possible for petroleum to be found in other types of rocks, such as metamorphic rocks that have undergone extreme heat and pressure, sedimentary rocks are by far the most common type of rock that contains petroleum. This is because the process of petroleum formation requires the accumulation and burial of organic matter, which is most likely to occur in sedimentary environments such as oceans, lakes, and swamps.
