Question 2 Report
A geyser is best described as/an
Answer Details
A geyser is best described as a fountain of superheated steam. This natural phenomenon occurs when water that is trapped beneath the Earth's surface is heated by geothermal activity, such as volcanic activity, deep underground. As the water is heated, it turns into steam and builds up pressure. This pressure eventually forces the steam and hot water to be expelled violently from the ground in a dramatic outburst, creating a fountain-like effect.
Let's break this down a bit more:
This distinct eruption is what characterizes a geyser and differentiates it from other geothermal features like hot springs or thermal pools, which do not erupt but simply release heat gradually into the water.

Question 5 Report
Which of the following are best explains the drift of population from rural to the cities in Nigeria?
Answer Details
The movement of population from rural areas to cities, commonly known as urbanization, is influenced by several factors, particularly economic and social opportunities. In the context of Nigeria, one of the most significant reasons is due to the availability of more job opportunities in the cities. Urban centers often offer a greater variety of employment possibilities compared to rural areas. These opportunities can be in industries, services, or various sectors requiring skilled and unskilled labor.
Economic development tends to be concentrated in cities, attracting individuals seeking better employment prospects and higher income potential. Many people move to urban areas in search of work that they cannot find in their rural hometowns, where agriculture may be the predominant source of livelihood with limited economic diversification.
Moreover, cities in Nigeria typically provide better recreational facilities and services than rural areas. These include access to modern amenities such as shopping centers, cinemas, sports facilities, and cultural events, which contribute to a higher quality of life. This aspect is appealing, particularly to younger generations, creating an added incentive for migration.
The other factors mentioned, such as food scarcity in rural areas, might contribute to migration but are often secondary compared to the employment factor. Many rural areas have agricultural activities, so food scarcity is not the primary reason; instead, it's the lack of economic opportunities that often triggers the movement.
Finally, while it is true that the cost of living in the cities is very high, especially in terms of housing and services, this is not a reason that attracts people to move. In fact, it might be a deterrent. Nonetheless, the potential for better income and lifestyle improvement in cities often outweighs the high cost of living for many migrants.

The process of head ward erosion will lead to the formation of
Answer Details
Let's understand the term **headward erosion**. **Headward erosion** refers to the process where a river or stream erodes its source region, causing the stream's origin to move backward away from the direction of water flow. This process can have several impacts and can lead to the formation of certain landforms.
Among the options provided, **headward erosion** is most commonly associated with the formation of **river capture**. When **headward erosion** continues over time, it can cause one river to extend its course and intersect with a neighboring river, capturing its flow. This event is known as **river capture** or **stream piracy**. Essentially, the rapid erosion at the river's source enables it to cut through the drainage divide and capture the headwaters of another river.
Let's briefly see why the other options are less relevant to **headward erosion**:
Therefore, the process of **headward erosion** most directly leads to the formation of **river capture**.

Question 10 Report
Which of the following is not an element of climate?
Answer Details
To determine which of the listed items is not an element of climate, we need to understand what elements constitute climate. **Climate** refers to the average weather conditions of a place over a long period, typically 30 years or more. The primary elements that define climate include **temperature**, **precipitation**, **humidity**, **wind**, and **air pressure**. Let's go through the choices given:
Precipitation: This is an important element of climate as it refers to any form of moisture that falls from the atmosphere to the earth's surface, such as rain, snow, or sleet.
Air pressure: This is a crucial element of climate because it influences wind patterns and weather systems such as cyclones and anticyclones.
Altitude: This is not an element of climate; rather, it is a geographic factor that influences climate. As you go higher in altitude, temperatures typically decrease, which can affect the climate of a region, but altitude itself is not a climatic element.
Temperature: This is a fundamental element of climate, affecting the average warmth or coldness of a place over time.
Therefore, **altitude** is not an element of climate, but a factor that can influence the other elements like **temperature** and **precipitation**.

The location of iron and steel industry at Ajakuta in Nigeria is best explained by the presence of (1) iron ore at Itakpe (11) limestone at Ewekoro (III) river port at Lokoja (IV) coal at Orukpa and Okaba
Answer Details
The location of the iron and steel industry at Ajaokuta in Nigeria can be best explained by considering certain factors critical to the iron and steel production process. These factors include **availability of raw materials**, **efficient transportation networks**, and **proximity to fuel sources**.
Firstly, the presence of **iron ore at Itakpe** is crucial because iron ore is the primary raw material needed for steel production. The proximity of Itakpe's iron ore deposits to Ajaokuta reduces transportation costs and ensures a steady supply of the primary raw material, enhancing the industry's efficiency. Therefore, **availability of iron ore is a significant consideration**.
Secondly, **limestone at Ewekoro** is essential because limestone is a critical component used in removing impurities during the steelmaking process, particularly in the blast furnace. Limestone acts as a flux which combines with impurities and forms slag that can be easily removed. **Proximity to limestone sources ensures access to necessary materials for processing**, which is a factor in choosing the location of the industry.
The presence of a **river port at Lokoja** facilitates the transportation of raw materials and finished products, as waterways provide a cost-effective and efficient means of transportation. This is important for both importing required materials and exporting the finished steel products.
Additionally, **coal at Orukpa and Okaba** is important as coal is often used to generate the high temperatures needed in steel production, either directly or through the production of coke, a coal derivative used in blast furnaces.
In conclusion, the location of the iron and steel industry at Ajaokuta is best explained by the presence of:
Therefore, the most relevant factors are the **availability of iron ore and limestone**, making the best answer "I and II only".

Answer Details
One of the major problems impacting the effective utilization of human resources in West Africa is unemployment.
Unemployment is a significant issue because it leads to several challenges that adversely affect both individuals and the economy at large. When people, especially those who are capable and willing to work, do not have jobs, it results in a waste of potential human resources. Let's break down a few reasons why unemployment is such a pressing problem:
Addressing unemployment requires collaborative efforts involving government policies, education systems, and private sector initiatives to create more job opportunities and develop skills that match the demands of the labor market. Therefore, unemployment remains a critical concern in achieving optimal utilization of human resources in West Africa.
Question 14 Report
The innermost section of the Earth is the
Answer Details
The innermost section of the Earth is the core. The Earth is composed of several layers, starting from the surface and moving inward. These layers, from the outside to the inside, are the crust, mantle, outer core, and inner core.
1. Crust: This is the outermost layer of the Earth. It is very thin compared to the other layers and is where we live. The crust is made up of solid rocks and minerals.
2. Mantle: Located beneath the crust, the mantle is composed of semi-solid rock that flows slowly. It is the largest layer of the Earth by volume.
3. Core: The core itself is divided into two parts: the outer core and the inner core. The outer core is made of molten, liquid metal, while the inner core is made of solid metal, primarily iron and nickel. The core is the hottest section of the Earth, with extremely high temperatures and pressures. It is situated at the center of the Earth and provides heat that helps power the movement of tectonic plates and causes volcanic activity.
Therefore, when we refer to the innermost section of the Earth, we are specifically talking about the core, and more accurately, the inner core.
Question 15 Report
When the sun is directly overhead at the tropic of Capricorn (23 %, °) on 22nd December, the Northern Hemisphere experiences it's
Answer Details
On 22nd December, the sun is directly overhead the Tropic of Capricorn in the Southern Hemisphere. This marks a significant event in both hemispheres.
In the Northern Hemisphere, this date corresponds to the **winter solstice**. Here's why:
The Earth is tilted on its axis by about 23.5 degrees. This tilt is responsible for the changing seasons. Throughout the year, different parts of the Earth receive varying amounts of sunlight depending on the planet's position in its orbit around the Sun.
During the winter solstice, the Northern Hemisphere is tilted farthest away from the Sun. As a result, it experiences the shortest day and the longest night of the year. The **winter solstice** marks the official start of winter in the Northern Hemisphere.
Thus, when the sun is directly overhead at the Tropic of Capricorn on 22nd December, the Northern Hemisphere experiences its **winter solstice**.
Question 16 Report
Which activity requires the following? I. Large area of land usually in thousands of hectares II. Availability of water either in the form of rain or irrigation III. High capital outlay
Answer Details
The activity that requires a large area of land usually in thousands of hectares, availability of water either in the form of rain or irrigation, and a high capital outlay is plantation agriculture. Let me explain why:
Large Area of Land: Plantation agriculture involves the cultivation of crops on a very large scale, often requiring thousands of hectares. This is necessary to achieve economies of scale and produce significant quantities of a specific crop such as tea, coffee, sugarcane, rubber, or oil palm.
Availability of Water: Crops grown on plantations need adequate water supply to thrive. This can be provided by regular rainfall or through irrigation systems. Thus, plantations are often located in regions with favorable climatic conditions or equipped with efficient water management systems.
High Capital Outlay: Establishing a plantation requires a significant initial investment. This includes procuring land and machinery, setting up irrigation systems, and maintaining infrastructure. Furthermore, plantations often rely on the employment of many workers and the use of advanced agricultural techniques, which also contribute to the high cost.
In contrast, the other activities mentioned do not primarily rely on these three factors to the same extent. For example, lumbering involves harvesting trees, which may also require substantial land area, but does not necessarily need irrigation. Tourism industry might require watering systems for landscaping, but its focus is more on site attractions. Finally, while mining requires high capital outlay and can cover large areas of land, it does not depend on the availability of irrigation systems like plantation agriculture does.
Question 17 Report
If the local time at a place X is 12.00 noon when the G.M.T is 5.00a.m then X is located on longitude
Answer Details
To determine the longitude of place X, we need to understand the relationship between time and longitude. The Earth is divided into 360 degrees of longitude, and it completes one full rotation (360 degrees) in 24 hours. Therefore, for every hour, the Earth rotates 15 degrees of longitude.
The given information is this:
The difference in time between GMT and the local time at place X is 7 hours (from 5:00 a.m. to 12:00 noon).
Calculation:
Now, we need to determine whether place X is east or west of the Prime Meridian (0° longitude, the reference line for GMT).
- Since the local time at place X is ahead of GMT (12:00 noon compared to 5:00 a.m.), it means X is east of the Prime Meridian.
Thus, place X is located on 105°E.
Question 18 Report
Which of the following environmental hazards is due primarily to human activities?
Answer Details
The environmental hazard that is due primarily to human activities is ozone depletion.
The ozone layer is a protective shield in the Earth's stratosphere that absorbs most of the Sun's harmful ultraviolet radiation. The thinning of the ozone layer is mainly caused by the release of man-made chemicals. The most significant contributors to this environmental hazard are chlorofluorocarbons (CFCs) and other ozone-depleting substances (ODS) which have been used in refrigeration, air conditioning, foam production, and aerosol propellants. When these chemicals reach the stratosphere, they break down ozone molecules, leading to what is known as the "ozone hole."
In contrast, the other environmental hazards listed—hurricanes, earthquakes, and volcanic eruptions—are natural phenomena. While human activities can influence the severity or impact of these events, such as through climate change exacerbating the intensity of hurricanes or human settlement in earthquake-prone areas, they are not primarily caused by human actions.

Answer Details
The **Gezira Scheme** and the **Manaquil Extension** are famous for the cultivation of **cotton**. These agricultural projects are located in **Sudan** and are among the largest irrigation projects in the world dedicated to agriculture.
The Gezira Scheme utilizes the waters of the **Blue Nile** to irrigate the land, making it suitable for growing cash crops. The scheme's infrastructure, including an extensive network of canals and ditches, supports the broad-scale cultivation of cotton. Similarly, the Manaquil Extension enhanced the irrigation reach, further bolstering cotton agriculture.
**Cotton** is highly suitable for growth in the hot climate of Sudan, especially under irrigation, as it requires a long growing season with plenty of sunshine and water. This makes it an ideal crop for the region, contributing significantly to Sudan's economy through both local use and export. Additionally, cotton plays a crucial role in the livelihood of many farmers in the region, being a major source of income.
Cultivating cotton in **Gezira** and **Manaquil** not only supports the textile industry but also generates employment for thousands of people engaged in farming, processing, and trade.
Question 20 Report

Answer Details
The angular distance of a point on the Earth's surface measured in degrees from the centre of the Earth east or west of the Greenwich Meridian is known as longitude.
Let's break this down to make it simple:
Longitude lines are imaginary lines that run from the North Pole to the South Pole. The most important line is the Greenwich Meridian, also called the Prime Meridian, which is the reference point for measuring longitude. It is designated as zero degrees (0°) longitude. When you measure how far east or west a point is from the Prime Meridian, you are measuring the longitude.
This is different from latitude, which measures the distance north or south of the Equator. Longitude lines meet at the poles, whereas latitude lines are parallel to each other.
Overall, longitude helps us determine the precise location of a place on Earth by specifying how far east or west it is from the Prime Meridian.
Question 21 Report
A mercury barometer is used for measuring
Answer Details
A mercury barometer is used for measuring atmospheric pressure.
Here's a simple explanation:
A barometer is an instrument designed to measure the pressure exerted by the atmosphere. The atmosphere exerts pressure because of the mass of air above the Earth, and this pressure changes as you move up and down in altitude or due to weather systems.
A mercury barometer consists of a long glass tube closed at one end and filled with mercury. The open end of the tube is placed in a bowl of mercury, called a reservoir. The pressure from the air pushing down on the mercury in the bowl forces the mercury up the tube. When the atmospheric pressure is high, the mercury in the tube rises, and when the atmospheric pressure is low, the mercury level falls.
Thus, by measuring the height of the mercury column in the tube, we can determine the atmospheric pressure. In summary, a mercury barometer provides a way to directly observe changes in the atmospheric pressure.
Question 22 Report
The world's busiest shipping routes are on the
Answer Details
The world's busiest shipping routes are found on the Atlantic Ocean. This ocean plays a crucial role in global trade and transportation due to several factors:
While other oceans like the Pacific and Indian Oceans are also important for global trade, the Atlantic Ocean remains particularly significant due to its connectivity and the economic powerhouses it links. The Antarctic Circle is not a major route due to its harsh environmental conditions and minimal human inhabitation, which reduces commercial sea traffic in that region.
Question 23 Report
In which part of the atmosphere does rain clouds develop?
Answer Details
Rain clouds most commonly develop in the troposphere. The troposphere is the lowest layer of Earth's atmosphere and extends from the Earth's surface up to about 8 to 15 kilometers (5 to 9 miles) above sea level, depending on your location.
This layer is where we experience weather, including rain, thunderstorms, and clouds. The reason for this is that the troposphere contains most of the atmosphere's water vapor, which is essential for cloud formation and precipitation.
In this layer, the air becomes cooler as you go higher, which allows the moist air to rise, cool, and condense to form clouds. When these clouds get heavy enough with condensed water droplets, they release the water in the form of rain.
The layers above the troposphere, such as the stratosphere, do not usually have the right conditions for rain cloud formation because they lack sufficient moisture and their temperatures are not typically conducive to the processes needed for cloud formation.

Answer Details
The equatorial diameter of the earth is approximately 6,760 km. This is the distance from the equator to the equator, passing through the center of the earth.
Question 26 Report
Answer Details
To determine which option is not a proof of the Earth's spherical shape, let's examine each one:
Twilight and Dawn: Twilight and dawn occur when the Earth rotates, and the sun is below the horizon. The gradual increase or decrease in light during these times is due to the atmosphere bending or scattering sunlight. While this phenomenon is observed worldwide, it by itself doesn't directly indicate a spherical Earth. Instead, it emphasizes the Earth's rotation, which is consistent with a spherical shape.
Lunar Eclipse: During a lunar eclipse, when the Earth is directly between the sun and the moon, the Earth casts a shadow on the moon. This shadow is observed as a circular shape, which provides direct evidence that the Earth is spherical.
Aerial Photograph: Aerial photographs, when taken from a sufficient altitude, can show the curvature of the Earth. Photographs taken from high altitudes give visual evidence of the Earth's curved surface, supporting the spherical shape.
Sunrise and Sunset: The occurrence of sunrise and sunset happens due to the Earth's rotation on its axis. As the Earth rotates, different parts of the world experience sunlight and darkness. This rotation is consistent with the global experience of a spherical planet.
Conclusion: While all the listed phenomena have some connection to the Earth's rotation and shape, **twilight and dawn** do not directly serve as a proof of the Earth's spherical shape. They are more indicative of the rotational aspect and atmospheric effects rather than the shape itself.
Question 27 Report

Answer Details
A line joining places having an equal degree of cloudiness is called an isoneph.
To understand this better, let's break down some related terms:
So, when we are specifically talking about cloudiness, the correct term and line is an isoneph. This is useful in meteorology for visualizing and analyzing patterns of cloud coverage across different regions.
Question 28 Report
Answer Details
When a ship appears over the distant horizon, the mast is seen before the hull. This phenomenon can be explained by considering the shape of the Earth and how light travels.
The Earth is a large sphere, and because of its curvature, objects that are farther away become obscured by the Earth's surface as they move over the horizon. The upper parts of an object, such as the mast of a ship, are further away from the Earth's surface compared to the lower parts, like the hull. As a result, the top parts become visible first as an object like a ship comes over the horizon.
Therefore, due to the curvature of the Earth, the mast, being higher and more elevated, comes into view before the hull as the ship approaches from a distance.
Question 29 Report
Which of the following best accounts for the decline in the importance of rail transport in Africa?
Answer Details
The decline in the importance of rail transport in Africa can be best explained by the high competition from road transport. Here's why:
Accessibility and Flexibility: Road transport is generally more accessible and flexible compared to railways. Roads are available in most areas of Africa, including rural regions, allowing goods and passengers to reach their destinations directly without requiring transfer between modes of transport.
Cost-Effectiveness: In many cases, road transport can be more cost-effective because it eliminates the need for transferring goods at several points. The initial investment in road infrastructure and vehicles can also be less than maintaining or upgrading railway networks.
Adaptability to Infrastructure Limitations: Many railways in Africa suffer from outdated infrastructure, which can hinder their efficiency and reliability. On the other hand, road transport can easily adapt to newer roads and infrastructures as they are developed.
Length of Transport Routes: Although Africa is a vast continent, many trade routes within countries or regions are more economically feasible with road transport, especially for short to medium distances.
Overall, while other factors such as the low volume of goods and potential retrenchment threats exist, the dominance and rapid improvement in the road transport sector particularly highlight why rail transport has seen a decline in relevance. The flexibility and economic viability of road transport often make it a more attractive choice for businesses and individuals alike.
Question 30 Report
Rocks which have been formed by the cooling and solidification of molten magma are called
Answer Details
Rocks that are formed from the cooling and solidification of molten magma are called igneous rocks.
To put it simply, when rocks melt deep beneath the Earth's surface because of the high temperatures, they turn into a liquid called magma. This magma can sometimes rise to the surface in the form of lava. Once either the magma or lava cools down and becomes solid, it forms a new type of rock known as igneous rock.
These rocks can be formed inside the Earth when the magma cools slowly, creating large crystals, or on the Earth's surface, when the lava cools quickly, often resulting in smaller crystals. The word "igneous" comes from a Latin word meaning "fire," which appropriately describes how these rocks form from the hot, molten magma.
Question 31 Report
All the major industrial zones of Nigeria owe their origin mainly to
Answer Details
The major industrial zones of Nigeria owe their origin mainly to the presence of cash crops. This is because, historically, Nigeria's economy largely depended on agriculture, and the availability of these cash crops provided a foundation for establishing industries. For example, regions where cash crops such as cocoa, palm oil, rubber, and groundnuts were abundantly grown became focal points for industries.
These crops were in high demand both locally and internationally, encouraging the establishment of processing industries to add value before export. This led to the development of infrastructure and contributed to the economic growth of these regions.
Thus, the presence of cash crops has played a significant role in shaping the industrial landscape of Nigeria by attracting investments, creating jobs, and fostering economic development in the respective regions.
Question 32 Report
The major source of power for most terrestrial ecosystems is
Answer Details
The major source of power for most terrestrial ecosystems is solar energy.
Let me explain why:
Solar energy is the energy that comes from the sun. It is critical for life on Earth as it powers the process of photosynthesis, which is used by plants, algae, and some bacteria to convert light energy into chemical energy. During photosynthesis, these organisms take in carbon dioxide from the air and water from the soil, and with the help of sunlight, they produce glucose and oxygen. This process provides the necessary energy and organic material to support life.
Here is why it is important:
In comparison, other energy sources like geothermal energy, nuclear power, and hydroelectric power play relatively minor roles in terrestrial ecosystems. These energies are not as directly involved in powering the basic life-sustaining processes as solar energy is. Therefore, it is clear that solar energy is the predominant power source for life on land.
Question 33 Report
Which of the following is a fossil fuel?
Answer Details
The term fossil fuel refers to energy sources that come from the remains of ancient plants and animals, buried and subjected to heat and pressure over millions of years. These fuels are primarily composed of carbon and include materials like coal, oil, and natural gas.
Among the options given:
Therefore, the correct answer is Lignite because it belongs to the category of fossil fuels. Lignite is formed from the remains of plants that lived millions of years ago, which makes it a source of stored energy that can be burned for heat and power.
Question 34 Report
Answer Details
The high population density in the Nile Valley is best explained by the presence of rich alluvial soil. The Nile River floods annually, depositing nutrient-rich silt along its banks, which creates fertile land perfect for agriculture. This fertile land supports farming, which is the primary means of livelihood for many people in the region. The availability of fertile soil allows for the cultivation of crops such as wheat, barley, and other foodstuffs, supporting a large population by providing food resources and encouraging human settlement. This agricultural productivity attracts people to settle, leading to a higher population density. It is not primarily due to climate, migration from Europe, or oil fields.
Question 35 Report
Which of the following least influences population density in Nigeria?
Answer Details
Population density refers to the number of people living per unit of area, typically measured in people per square kilometer. In Nigeria, several factors influence population density, including natural, economic, and social factors.
Thick forest vegetation can influence population density by limiting the availability of land for habitation and agricultural activities. Areas with dense forests are usually less populated because they are harder to clear for settlements and farming. Additionally, thick forests may not have sufficient infrastructure, making them less attractive for people to live in.
Similarly, tsetse fly infestation can significantly influence population density. The tsetse fly transmits sleeping sickness, which can be a health hazard for humans and animals. Areas infested with tsetse flies might have lower population densities because people avoid settling in regions where their health and that of their livestock are at risk.
Fertile agricultural land attracts people because it supports farming activities, which is a primary livelihood for many people in Nigeria. As a result, such areas often have higher population densities due to the economic opportunities they provide.
The factor that least influences population density among the given options is mining. While mining can attract workers to specific areas, its influence is usually limited to certain regions where mineral resources are available. Since mining is typically localized and not widespread, its impact on overall population density is generally lower compared to factors like agriculture or disease. Additionally, mining areas might not have sustainable living conditions to attract large populations permanently.
In summary, while all these factors can influence population density, mining has the least impact compared to the other options because it affects fewer regions and often does not provide long-term settlement opportunities.

Answer Details
A **coastal plain** is a **large expanse of low, level land** that is formed due to an **uplift of part of the sea floor bordering a continent**. Essentially, it is an area where the land is relatively flat and is located near the coast.
This type of landform often occurs due to geological activities over time where the sea floor is pushed upwards, resulting in a broad, flat land surface extending inland from the coast. Coastal plains are typically characterized by their flat terrain and proximity to the ocean, making them influenced by marine conditions.
In summary, **a coastal plain is the result of the elevation of a portion of the sea floor adjacent to the continent**. It is characterized by its flatness and location near the sea, distinguishing it from other types of plains such as deltaic, outwash, or flood plains which have different formation processes and characteristics.
