Question 1 Report
Caverns, dry valleys and underground drainage are associated with which of the following areas?
Answer Details
Caverns, dry valleys, and underground drainage are associated with limestone areas. Limestone is a sedimentary rock that is formed from the accumulation of calcium carbonate over time. It is easily dissolved by water, which can create underground drainage systems and caverns. Caverns are large underground chambers or cave systems that are formed by the erosion of limestone by water. Dry valleys are valleys or channels that are formed when a river or stream flows underground through a limestone area, leaving the surface dry. Mountainous areas can also have caverns and underground drainage, but limestone areas are the most commonly associated with these features due to the unique properties of the rock. Coastal areas are typically associated with erosion by the sea and the formation of sea caves. Desert areas are characterized by low precipitation and are less likely to have extensive underground drainage systems.
Question 2 Report
Transportation helps economic development through all the following except
Answer Details
Transportation does not necessarily help in the distribution of the human population. While transportation does facilitate the movement of people and commodities, promote national and international trade, and diffuse ideas and technology, it does not necessarily result in a more even distribution of the population. For example, transportation infrastructure can lead to urbanization and the concentration of people in certain areas, rather than spreading them out more evenly across a region. The location and availability of transportation options can also influence where people choose to live and work, leading to imbalances in population distribution. In simple terms, transportation helps in many ways to support economic development, but it does not always result in a more even distribution of the population.
Question 4 Report
The busiest ocean trade route is the
Answer Details
The busiest ocean trade route is the North Atlantic route. The North Atlantic route is a major shipping lane that connects Europe to North America, passing through the Atlantic Ocean. It is the busiest ocean trade route due to the high volume of goods and materials that are transported between Europe and North America, including crude oil, manufactured goods, and food products. The route is also significant because it connects the major ports of Europe, such as Rotterdam and Antwerp, to major ports in North America, such as New York and Montreal. The North Atlantic route is a critical component of global trade, and the high volume of shipping traffic on this route makes it the busiest ocean trade route in the world.
Question 5 Report
Which of the following is a drainage pattern?
Answer Details
A drainage pattern that is represented by one of the options given is the Trellis pattern. A drainage pattern is a geological term that describes the layout of the network of channels that make up a river system. It is influenced by the underlying geology, topography, and climate of a region. There are several types of drainage patterns, including dendritic, trellis, radial, rectangular, and parallel patterns. The Trellis drainage pattern is characterized by a main river channel that is joined at nearly right angles by smaller tributaries. The pattern is usually formed in regions with folding or parallel folding of rock layers. The tributaries usually form in valleys between the ridges formed by the folds, and they flow into the main channel, which runs parallel to the ridges. The pattern resembles a garden trellis or net, with the main channel representing the vertical lines and the tributaries the horizontal lines. Therefore, the Trellis pattern is a type of drainage pattern characterized by smaller tributaries joining the main river channel at nearly right angles.

Question 8 Report
Which of the following igneous intrusions is horizontally inclined?
Answer Details
Igneous intrusions are formed when magma solidifies and becomes rock. There are several types of igneous intrusions, and they can be classified based on their shape, size, and orientation. A sill is a type of igneous intrusion that is formed when magma is injected parallel to the layers of existing rock and solidifies. This creates a horizontal or near-horizontal sheet-like intrusion that is parallel to the surrounding rock. Therefore, the answer is: Sill. A sill is horizontally inclined and can be distinguished from other types of igneous intrusions like dykes, laccoliths, and batholiths, which have different shapes and orientations.

Question 10 Report
Two opposite longitudes form
Answer Details
Longitude is the angular distance of a location on Earth's surface east or west of the Prime Meridian, which is an imaginary line that runs from the North Pole to the South Pole and passes through Greenwich, England. Two opposite longitudes form a Great Circle. A Great Circle is a circle on the surface of a sphere that has the same center as the sphere. It is the largest possible circle that can be drawn on a sphere and divides the sphere into two equal hemispheres. Therefore, the answer is: a Great Circle. Two opposite longitudes form a Great Circle, while the Equator is an imaginary circle that lies at 0 degrees latitude, the International Dateline is an imaginary line that runs roughly from the North Pole to the South Pole and defines the change of calendar days, and the Arctic Circle is an imaginary circle that lies at 66.5 degrees North latitude.
Question 11 Report
Subsistence farming is practiced when people
Answer Details
Subsistence farming is practiced when people grow crops for their own consumption. The goal of subsistence farming is to produce enough food to feed a family or community, rather than for sale or trade. This type of farming is often found in rural or remote areas where there is limited access to markets for buying or selling goods. Subsistence farming is different from growing only one crop, growing many crops for export, or exporting only one crop. These activities are focused on producing crops for sale or trade, rather than for personal consumption. In simple terms, subsistence farming is when people grow crops to feed themselves and their families, rather than for sale or trade.
Question 12 Report
Rift valleys are formed through which of the following processes?
Answer Details
Rift valleys are formed through a process called faulting. Faulting occurs when the Earth's crust cracks and breaks along two parallel faults, causing the land between the faults to sink and form a valley. This process can happen over a long period of time and can be caused by various geological factors, such as tectonic plate movements, volcanic activity, and changes in the Earth's crust. In simple terms, rift valleys are formed when the ground splits and sinks along two cracks, creating a valley between them. This splitting and sinking of the land is called faulting and is caused by various geological processes.

Answer Details
Question 14 Report
Which climatic type has winter rain
Answer Details
The climatic type that has winter rain is the Mediterranean climate. The Mediterranean climate is characterized by mild, wet winters and hot, dry summers. This type of climate is found in coastal regions bordering the Mediterranean Sea, as well as in other regions with similar climates, such as California in the United States. The winter rains in Mediterranean climates are a result of the prevailing westerly winds, which bring moist air from the Atlantic Ocean. This moisture is then deposited as rain in the coastal regions with Mediterranean climates, providing a source of water during the typically dry summer months. The winter rain and the mild temperatures of the Mediterranean climate make it ideal for growing a wide variety of crops, including fruits, vegetables, and wine grapes.
Question 15 Report
A settlement type in which buildings are aligned along a road or river is said to be
Answer Details
A settlement type in which buildings are aligned along a road or river is said to be linear. This means that the buildings are arranged in a line or series along the road or river. This type of settlement pattern is often seen in areas with transportation routes, where people and goods need to move easily along a path. Linear settlements can be found in various forms, such as a single row of buildings or a series of parallel rows. They are different from nucleated or clustered settlements, where buildings are grouped together in a tight cluster, and dispersed settlements, where buildings are spread out across the landscape.
Question 16 Report
Which of the following is not a volcanic feature?
Answer Details
Volcanoes are formed when magma, ash, and gas escape from a magma chamber and rise to the Earth's surface. There are several types of volcanic features that are formed by this process. A ventifact is not a volcanic feature. A ventifact is a geological feature that is formed by the erosive action of wind-blown sand on rocks. Over time, wind-blown sand can abrade rocks and create unusual shapes and formations. Therefore, the answer is: Ventifact. Ventifacts are not related to volcanic activity and are formed by the action of wind on rock surfaces, while calderas, geysers, and dykes are all volcanic features formed by the movement of magma and other volcanic material.

Answer Details
The statistical method represented above is a flow chart. The flow chart is a graphical representation of the volume and direction of passenger traffic between IZABU town and its surrounding towns in the year 2001. Each line on the chart represents 1,500 persons who travelled between two towns, and the direction of the line indicates the direction of travel. The width of the line may indicate the relative volume of passengers who traveled between the two towns. Therefore, a flow chart is a type of diagram that shows the movement of objects or people between different locations or stages.
Question 18 Report
What is the sum total of human resources available in a country called?
Answer Details
The sum total of human resources available in a country is called its population. Population refers to the total number of people who live in a specific geographic area, such as a city, state, or country. It is usually measured by a census, which is a survey that counts every person in a given area. Population is an important measure of a country's human resources because it can provide insight into the size and demographics of the workforce, as well as the overall social and economic characteristics of the country. Therefore, the total number of people living in a country is called its population.
Question 19 Report
Which of the following rocks is not metamorphic
Answer Details
The rock that is not metamorphic is Shale. Metamorphic rocks are formed from pre-existing rocks that have undergone physical and chemical changes due to high pressure, heat, or both. The process of metamorphism can cause the minerals in the original rock to recrystallize and form new minerals, resulting in a change in texture and composition. Schist, quartzite, and slate are all examples of metamorphic rocks. Schist is formed from shale or mudstone that has undergone high pressure and heat, causing the minerals in the rock to recrystallize into thin, platy layers. Quartzite is formed from sandstone that has undergone a process of recrystallization, cementation, and metamorphism. Slate is formed from shale or mudstone that has undergone low-grade regional metamorphism. Shale, on the other hand, is a sedimentary rock that is formed from compacted mud or clay. It is not formed through the process of metamorphism and therefore cannot be classified as a metamorphic rock. Therefore, Shale is the rock that is not metamorphic.
Question 20 Report
The instrument, barometer, is used for measuring
Answer Details
The instrument barometer is used for measuring air pressure. It works by measuring the weight of the air pressing down on the surface of a liquid (usually mercury or water) in a tube. The higher the pressure, the more the liquid is pushed up the tube. This can be used to determine changes in atmospheric pressure, which can indicate changes in the weather.

Question 22 Report
Which of the following features is found in the upper course of a river?
Answer Details
One feature that is found in the upper course of a river is a gorge. The upper course of a river is where it begins, typically in upland or mountainous areas, and is characterized by steep gradients, high energy, and narrow channels. Gorges are deep, narrow valleys with steep sides that are formed by the erosive power of the river as it cuts down into the landscape. They are a common feature in the upper course of a river where the water is moving quickly and eroding the surrounding rocks and soil. Levees, ox-bow lakes, and deltas are features that are typically found in the middle and lower courses of a river where the water is moving more slowly and has less erosive power.
Question 23 Report
The density of the earth's crust varies from
Answer Details
The density of the earth's crust varies from 2.5 g/cm3 to 3.3 g/cm3. The Earth's crust is the outermost layer of the Earth, and is composed of various minerals and rocks. The density of the crust varies depending on its composition, with lighter minerals like quartz and feldspar having lower densities than heavier minerals like iron and magnesium. Overall, the average density of the Earth's crust is around 2.7 g/cm3, which is much lower than the densities of the Earth's mantle and core. It is important to note that the density of the crust can also vary locally depending on factors like the presence of mineral deposits or the formation of mountains and other geologic features.

Question 26 Report
A rapid population growth can result from
Answer Details
Rapid population growth occurs when the number of births exceeds the number of deaths in a population. This can be influenced by several factors, including improved medical care, which reduces the number of deaths, and an absence of natural hazards that can also cause death. Additionally, if family planning methods are not widely used, then there may be a higher number of births, which can contribute to rapid population growth. Therefore, the absence of factors that limit population growth, along with improvements in healthcare, can lead to a rapid increase in population.
Question 27 Report
A crescentic depositional feature found in desert mice is
Answer Details
A crescentic depositional feature found in desert mice is a Barchan dune. This type of dune is shaped like a crescent moon and has horns pointing downwind. Barchan dunes form in areas where there is a limited supply of sand, and wind blows predominantly from one direction. As sand is blown up the windward side of the dune, it accumulates and forms the crescentic shape. The wind then moves the sand over the crest and down the leeward slope, creating the horns. Barchan dunes can range in size from a few meters to several hundred meters, and are commonly found in desert regions around the world.
Question 29 Report
Most industries in the West African sub-region are
Answer Details
Most industries in the West African sub-region are small-scale. Small-scale industries are those that produce goods or services on a small or localized scale, often using simple technologies and manual labor. In West Africa, many industries are small-scale because the region has a largely rural and informal economy, with many people working in agriculture and informal trade. Small-scale industries can include food processing, textiles, handicrafts, and construction materials. While there are some large-scale industries in the region, such as mining and oil production, these tend to be concentrated in specific areas and are often dominated by foreign companies. Small-scale industries can provide important opportunities for local employment and economic development in the region. They can also be more adaptable to local conditions and needs than large-scale industries.

By how much is the traffic between IZABU and Anikpu more than the traffic between IZABU and Ugba?
Answer Details
The traffic between IZABU and Anikpu is more than the traffic between IZABU and Ugba by 1,500 people. To determine this, we can compare the length of the lines in the diagram. The line representing the traffic between IZABU and Anikpu is longer than the line representing the traffic between IZABU and Ugba, which means that more people are traveling between IZABU and Anikpu than between IZABU and Ugba. According to the scale, one line represents 1,500 people, so if the line between IZABU and Anikpu is 1 unit longer than the line between IZABU and Ugba, that means the difference in traffic is 1,500 people. In simple terms, the difference in traffic between IZABU and Anikpu compared to IZABU and Ugba is 1,500 people, as shown by the difference in the length of the lines in the diagram.
Question 31 Report
How many standard time zones will a country with a longitudinal extent of 150° have?
Answer Details
The Earth has 360 degrees of longitude, and there are 24 standard time zones spread across the Earth's surface, with each standard time zone covering 15 degrees of longitude. Therefore, a country with a longitudinal extent of 150 degrees would cover 10 standard time zones (150/15). The number of standard time zones a country covers depends on the country's longitudinal extent, and how many 15 degree segments that extent covers. So, the correct answer is 10.

Which of the following areas in Tropical Africa is densely populated?
Answer Details
South-western Nigeria is densely populated in Tropical Africa. Densely populated areas are those with a high concentration of people living in a given area. In Tropical Africa, there are several factors that influence population density, including climate, soil, vegetation, and water resources. South-western Nigeria has a high population density compared to the other regions mentioned. This is due to several reasons, including favorable climate and fertile soil, which are suitable for agriculture. Also, the region is home to several urban centers, including Lagos, which is one of the most populous cities in Africa. The middle belt of West Africa, the Sahel region of West Africa, and the Niger Delta have lower population densities compared to South-western Nigeria. The middle belt of West Africa is characterized by savannah grassland, while the Sahel region of West Africa is characterized by arid and semi-arid climate. The Niger Delta region is dominated by a network of rivers, creeks, and swamps, which make the area difficult to inhabit. Therefore, South-western Nigeria is the most densely populated area in Tropical Africa among the regions mentioned.
Question 42 Report
Which of the following examples of igneous rock is extrusive?
Answer Details
Igneous rocks are formed from the solidification of magma or lava. Depending on where the rock cools and solidifies, it can be classified as either extrusive or intrusive. Extrusive rocks are formed when lava from a volcanic eruption cools quickly on the surface of the earth, forming small crystals or no crystals at all. On the other hand, intrusive rocks are formed when magma cools slowly underground, allowing larger crystals to form. Out of the four examples of igneous rock, basalt is the only extrusive rock. Basalt is formed from the rapid cooling of lava on the surface of the earth, resulting in small or no crystals. Granite, gabbro, and diorite, on the other hand, are all intrusive rocks that formed from slow cooling of magma deep within the earth, resulting in larger crystals. Therefore, the correct answer is "Basalt".
Question 45 Report
Banking, insurance, and teaching are examples of which industry?
Answer Details
Banking, insurance, and teaching are examples of the tertiary industry. The tertiary industry refers to the service sector of an economy, which involves the provision of services to individuals and businesses. This industry includes activities such as banking, insurance, education, healthcare, hospitality, and professional services such as accounting, consulting, and legal services. In contrast, the primary industry refers to the sector of an economy that involves the extraction and production of natural resources, such as agriculture, forestry, fishing, and mining. The secondary industry refers to the sector of an economy that involves the manufacturing of goods, such as the production of cars, clothing, electronics, and other products. So, banking, insurance, and teaching are examples of the tertiary industry because they are service-based industries that provide services to individuals and businesses, rather than producing goods or extracting natural resources.
Question 46 Report
What is the local time in Town X at 45° E, when it is noon at 0°?
Answer Details
To determine the local time in Town X at 45° E when it is noon at 0°, we need to calculate the time difference between the two locations and add it to or subtract it from noon at 0°. Since every 15 degrees of longitude represents one hour of time difference, the longitude difference between 0° and 45° E is 45 ÷ 15 = 3 hours ahead of the 0° time zone. So, if it is noon at 0°, it would be 3:00 pm in Town X (0 + 3 = 3) since Town X is 3 hours ahead of the 0° time zone. Therefore, the answer is 3:00 pm.
Question 47 Report
Which of the following elements of climate is used in the Greek System of climate classification?
Answer Details
The Greek System of climate classification is based on temperature, which is the main element used to classify different climates. This system divides climates into three main categories based on average temperature: the tropical, temperate, and polar climates. Within each of these categories, there are further subdivisions based on temperature and other factors such as rainfall, humidity, and pressure. For example, the Mediterranean climate is a subdivision of the temperate climate category and is characterized by mild, wet winters and hot, dry summers. Therefore, the element of climate used in the Greek System of climate classification is temperature. While other factors such as rainfall, humidity, and pressure are considered, they are not the primary factors used to classify climates in this system.
Question 48 Report
The predominant process of weathering in the desert region is
Answer Details
The predominant process of weathering in the desert region is physical weathering. Physical weathering is the breakdown of rocks into smaller pieces without changing their chemical composition. In the desert region, temperature changes and the movement of wind-blown sand and rock fragments can cause physical weathering. Over time, rocks in the desert are broken down into smaller pieces and eventually into sand, which can then be carried away by the wind. While chemical and biological weathering can also occur in the desert, physical weathering is the most common due to the unique environmental conditions in this region.

Question 51 Report
Write a geographical account of road transportation under the following headings:
(a) three advantages;
(b) three disadvantages;
(c) four contributions to development.
Road Transportation
(a) Advantages of road transportation
- Door-to-door service and flexibility: Road vehicles can collect passengers and goods from their point of origin and deliver them directly to their destination. They can also use different routes where necessary.
- Suitable for short distances: It is convenient and relatively economical for moving people, farm produce and light goods over short distances, especially within and between towns.
- Wide coverage: Roads reach many rural, interior and isolated settlements where rail, air and water transport may not be available. They also complement other modes of transport by carrying goods to and from railway stations, airports and seaports.
(b) Disadvantages of road transportation
- Limited carrying capacity: Road vehicles generally carry smaller loads than trains and ships; consequently, they are less suitable for very heavy or bulky goods over long distances.
- Accidents and congestion: Road transport is prone to accidents which cause loss of lives and property. Traffic congestion, particularly in large towns, also delays the movement of people and goods.
- High maintenance cost and environmental problems: Roads may be damaged by heavy rainfall, flooding and erosion, making repairs expensive. Motor vehicles also produce noise and air pollution.
(c) Contributions of road transportation to development
- Promotion of trade: Roads link areas of production with markets and consumption centres. They enable raw materials to reach industries and manufactured goods to reach consumers, thereby promoting internal and external trade.
- Development of agriculture: Good roads enable farmers to obtain inputs such as fertiliser, seedlings and machinery, and allow farm produce, especially perishable produce, to be transported quickly to markets. This encourages commercial farming.
- Employment and income generation: Road construction and maintenance, vehicle operation, haulage services, repairs and roadside trading provide employment and income to many people. Government also earns revenue through vehicle licences, road taxes and tolls.
- Opening up and integrating settlements: Roads open up rural and interior areas, encourage the growth of new settlements and towns, facilitate administration, promote tourism and national integration, and improve access to schools, hospitals and other social services.

- Soil and agriculture: fertile soils that support good farming attract dense settlement; infertile land repels it.
- Job opportunities and industrialisation: areas with industry, commerce, mineral deposits and good transport attract people in search of work, giving high densities.
(c) Three factors that cause increase in world human population
- Increase in birth rate, encouraged by early marriage and preference for large families.
- Decrease in death rate through improved medical facilities, hygiene and sanitation.
- Adequate food supply and improved standard of living from better agriculture.
Question 53 Report
(a) Outline five factors which an industrialist will consider when locating a fruit canning industry.
(b) Explain five benefits derived from the concentration of manufacturing industries in urban centers.
(a) Five factors an industrialist will consider when locating a fruit canning industry
- Nearness to raw materials: Fruits are bulky and perishable, so the factory must be sited close to the fruit-growing area to reduce spoilage and transport cost.
- Availability of water: Large quantities of clean water are needed for washing, processing and cooling the fruits, so a reliable water supply is essential.
- Supply of labour: Both skilled and unskilled workers are needed for sorting, processing and operating machines, so the site should have access to adequate labour.
- Availability of market: The industry should be located near, or well connected to, a large market so that the canned products can be sold quickly.
- Transport and power: Good roads, railways or ports for moving raw materials and finished goods, and a steady supply of electric power to run the machines, are important considerations (capital and government policy are also relevant).
(b) Five benefits from the concentration of manufacturing industries in urban centres
- Provision of employment: The clustering of many industries creates numerous jobs, reducing unemployment in the town.
- Shared infrastructure: Industries share roads, electricity, water and communication facilities, which lowers the cost of production for each firm.
- Availability of skilled labour: A concentration of industries attracts and pools a large body of skilled and specialised workers that all the firms can draw upon.
- Ready market and linkages: Industries located together serve as markets for one another; the by-product or output of one becomes the raw material of another, encouraging linked industries.
- Availability of services: Banks, insurance, repair workshops, warehousing and research facilities develop to serve the industries, improving efficiency and growth of the urban economy.

Question 54 Report
(a) Draw an outline map of Nigeria.
On the map, locate and name:
(i) one national park in the north that is important for tourism;
(ii) one national park in the south that is important for tourism;
(iii) Calabar town.
(b) Outline four factors that retard tourism development in Nigeria.
(c) Suggest three ways by which tourism can be promoted in Nigeria.
(a) Outline map of Nigeria
Key: Kainji Lake National Park is located in the north-western/central part of Nigeria, around Niger and Kwara States. Cross River National Park is located in Cross River State in the south-east. Calabar is located in the south-east, near the Cross River estuary and the Atlantic coast.
(b) Factors that retard tourism development in Nigeria
- Insecurity: kidnapping, insurgency, armed robbery and communal conflicts discourage local and foreign tourists.
- Poor infrastructure: bad access roads, irregular electricity and water supply, poor communication facilities and inadequate standard hotels make tourist centres unattractive.
- Inadequate publicity and funding: many tourist attractions are poorly advertised and lack funds for development, maintenance and modern facilities.
- Poor management and shortage of skilled personnel: inadequate trained tourist guides, poor maintenance of sites and inefficient tourism agencies reduce the quality of services offered.
(c) Ways of promoting tourism in Nigeria
- Government should provide adequate security and patrol tourist centres and access routes.
- Good roads, hotels, water supply, electricity, communication facilities and other social amenities should be provided at tourist sites.
- Tourist attractions should be widely advertised through the media, schools, exhibitions and international tourism agencies.

Question 55 Report
(a) Draw a sketch map of Nigeria. On the map, show and name: (i) one cocoa growing belt; (ii) one groundnut growing belt; (iii) one town in 4(a)(i).
(b) Describe three physical conditions necessary for the cultivation of groundnut.
(c) Explain four ways in which groundnut cultivation has contributed to the economy of Nigeria
(a) Sketch map of Nigeria
The shaded south-western belt represents the cocoa-growing belt, and Ife is a town within it. The shaded northern belt represents a groundnut-growing belt.
(b) Physical conditions necessary for the cultivation of groundnut
- Moderate rainfall: Groundnut requires about 500 to 1,000 mm of rainfall annually, mainly during its growing period. A dry spell is required for ripening, harvesting and drying the pods.
- High temperature and sunshine: It grows best under high temperatures of about 25°C to 30°C with abundant sunshine.
- Suitable soil and relief: Loose, light, sandy or sandy-loam soil that is well drained is required so that the pegs can penetrate the soil and the pods can develop easily. Fairly level or gently undulating land is favourable.
(c) Ways in which groundnut cultivation has contributed to the economy of Nigeria
- Employment creation: It provides employment for farmers and for people engaged in processing, bagging, transport, marketing and export.
- Source of income: Sale of groundnut and groundnut products gives income to farmers, traders and processors, thereby improving their standard of living.
- Foreign exchange earnings: Export of groundnut, groundnut oil and groundnut cake earns foreign exchange for Nigeria and helps to diversify the economy.
- Raw materials and food: Groundnut supplies oil mills and soap industries with raw materials, while groundnut cake is used in animal-feed manufacture. The nuts and oil also provide important protein-rich food for the population.
