WAEC SSCE - Geography - 2019 (Objective)

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.

Batholith

Maelezo ya Majibu

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.

Maelezo ya Majibu

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.

Maelezo ya Majibu

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.

Maelezo ya Majibu

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.

Caverns, dry valleys and underground drainage are associated with which of the following areas?

Coastal

Limestone Jibu sahihi

Mountainous

Maelezo ya Majibu

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.

3.00 am

Maelezo ya Majibu

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.

Maelezo ya Majibu

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.

Maelezo ya Majibu

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.

Which of the following rocks is not metamorphic

Shale Jibu sahihi

Schist

Quartzite

Slate

Maelezo ya Majibu

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.

Maelezo ya Majibu

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.

Maelezo ya Majibu

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.

Maelezo ya Majibu

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.

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.

Maelezo ya Majibu

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.

Which of the following examples of igneous rock is extrusive?

Granite

Basalt Jibu sahihi

Gabbro

Diorite

Maelezo ya Majibu

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".

Maelezo ya Majibu

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.
