A prominent erosional landform of wind action is a?
Bayanin Amsa
A prominent erosional landform of wind action is called a "yardang". A yardang is a streamlined ridge that is created by the erosion of windblown sedimentary rocks. When strong winds blow across the landscape, they can cause the rocks to become eroded and sculpted into elongated ridges with a sharp, pointed crest and steep slopes. Yardangs are typically found in arid regions and are often aligned with the direction of the prevailing wind. They are an important feature of desert landscapes and can range in size from a few meters to several kilometers in length.

An example of a non-renewable resources is?
Bayanin Amsa
An example of a non-renewable resource is solid mineral. Non-renewable resources are natural resources that cannot be easily replenished or regenerated, and once they are used up, they are gone forever. Solid minerals such as coal, oil, and natural gas are finite resources that were formed over millions of years through geological processes, and their reserves are being depleted much faster than they are being replaced. Other examples of non-renewable resources include minerals, metals, and some types of groundwater. It is important to use these resources wisely and efficiently, and to develop alternative sources of energy and materials that are renewable and sustainable.

The most important impact of migration on population is?
Bayanin Amsa
The most important impact of migration on population is the redistribution of the population. Migration involves the movement of people from one place to another, resulting in a change in the population distribution of both the sending and receiving regions. This movement can lead to a decrease or increase in the population of the sending region and an increase in the population of the receiving region. The impact of migration can be seen in demographic changes, such as changes in age structure, fertility, mortality, and population growth rates, which can have significant economic, social, and political consequences.

If the population of an area is 690 million and the land area is 300 000 km2,the population density is approximately?
Bayanin Amsa
To calculate population density, we need to divide the population of an area by its land area. Population density = Population / Land area Given that the population of the area is 690 million and the land area is 300,000 km2, we can calculate the population density as: Population density = 690,000,000 / 300,000 = 2,300 persons per km2 Therefore, the population density is approximately 230 persons per km2. The correct answer is the option: 230 persons per km2.

A town that is situated where two rivers meet is a?
Bayanin Amsa
A town that is situated where two rivers meet is called a confluence town. A confluence is the point where two or more rivers come together and merge into a single larger body of water. Towns located at the confluence of two rivers often have strategic importance as they provide a natural crossing point and a location for trade and commerce. These towns can also be important for agriculture and fishing, as the merging of two rivers can create a fertile and productive environment. Examples of confluence towns include Kanpur in India, where the Ganges and the Yamuna rivers meet, and Pittsburgh in the United States, where the Allegheny and Monongahela rivers meet to form the Ohio River.

The main components of the land ecosystem are?
Bayanin Amsa
The main components of the land ecosystem are vegetation, soil, lithosphere, and animals. Vegetation refers to all the plants that grow in a particular area. Plants are important components of the land ecosystem because they provide food and shelter for animals, as well as oxygen for the atmosphere. Soil is the layer of earth that supports plant growth. It is made up of a mixture of minerals, organic matter, water, and air. Soil is important for the land ecosystem because it provides the nutrients and water that plants need to grow. The lithosphere is the solid, outermost layer of the Earth. It includes the rocks and minerals that make up the Earth's crust. The lithosphere is important for the land ecosystem because it provides the foundation for soil formation and supports plant growth. Animals are also important components of the land ecosystem. They play a crucial role in pollinating plants, dispersing seeds, and controlling the populations of other organisms. Together, these components work together to create a complex and dynamic ecosystem that supports life on land. The interactions between vegetation, soil, lithosphere, and animals are essential for the survival of the ecosystem and the organisms that depend on it.

In the equatorial region, most rainfall results from?
Bayanin Amsa
In the equatorial region, most rainfall results from the conventional effect. The conventional effect occurs when the sun heats the earth's surface, causing warm air to rise and cool air to sink. As the warm air rises, it cools and condenses, forming clouds. These clouds then release their moisture as rainfall. In the equatorial region, the sun's rays are most intense, and the land and water surfaces are warm, causing warm air to rise and leading to the formation of abundant rainfall. Other factors such as humidity and wind patterns can also influence rainfall in the equatorial region. However, the conventional effect is the primary cause of rainfall in this region.

Rocks can be classified into three major groups according to their?
Bayanin Amsa
Rocks can be classified into three major groups according to their origin and appearance. The three major groups of rocks are igneous, sedimentary, and metamorphic rocks. Igneous rocks are formed from cooled and solidified magma or lava. Sedimentary rocks are formed from the accumulation of sediment or organic matter that has been compacted and cemented together. Metamorphic rocks are formed from the transformation of pre-existing rocks due to heat, pressure, or chemical reactions. The appearance of a rock, such as its color and texture, can also provide clues about its origin and formation process. Therefore, the classification of rocks is based on both their origin and appearance.

Migrant receiving regions tend to be characterized by?
Bayanin Amsa
Migrant receiving regions tend to be characterized by a low per capita income. Low-income regions often attract migrants who are seeking better economic opportunities, either within their own country or from abroad. These regions may offer low-paying jobs that are not attractive to local workers but are more attractive to migrants who are willing to work for lower wages. Migrants may also be attracted to low-income regions because the cost of living is generally lower, which means that their money can go further than it would in a higher-income region. In addition, low-income regions may have less stringent immigration policies, making it easier for migrants to enter and stay in the country. Overall, low-income regions tend to have a higher demand for labor, and this demand is often met by migrant workers who are willing to work for lower wages. While this can benefit the economy of the receiving region, it can also create social and economic challenges, such as discrimination, exploitation, and overcrowding.

An effect of global warming is?
Bayanin Amsa
An effect of global warming is the rise in the volume of ocean waters. As the earth's temperature increases due to global warming, the polar ice caps start melting, and the water from them flows into the ocean. This leads to a rise in the sea level and can cause flooding in coastal areas. Additionally, global warming can also cause the expansion of ocean water due to increased temperature, contributing to the rise in sea level.

The intra-city movement of passengers in most Nigerian towns is largely by?
Bayanin Amsa
The intra-city movement of passengers in most Nigerian towns is largely by service buses. This is because service buses provide an affordable and efficient means of transportation for the majority of people who cannot afford to own private cars or use taxis. In addition, service buses are able to navigate the often congested and narrow roads in urban areas, making them a popular choice for commuters. While taxis and motorcycles are also used for intra-city transportation in Nigeria, they are generally more expensive and less accessible than service buses, particularly for those on lower incomes. Rail transport, on the other hand, is not widely available for intra-city transportation in Nigeria.

Which of the following items may not be necessary for a chain survey?
Bayanin Amsa
The item that may not be necessary for a chain survey is the "prismatic compass." A chain survey is a type of surveying method that is used to measure land areas for mapping and planning purposes. The process involves the use of a chain or a tape to measure the distance between various points on the ground, and the use of ranging poles or arrows to mark the locations of these points. A Gunter's chain is used to measure distances in chain surveys, and ranging poles are used to mark the endpoints of each measured distance. An arrow head is used to mark the points being surveyed. While a prismatic compass is sometimes used to determine the direction of a line, it is not always necessary for a chain survey, as the direction of a line can also be determined using other methods such as a magnetic compass or by sighting along a straight edge.

Which of the following factors mostly accounts for high population density in West Africa cities?
Bayanin Amsa
The concentration of industries mostly accounts for high population density in West African cities. Industries provide employment opportunities and attract people from surrounding rural areas seeking work. As the population grows, the demand for housing, social amenities, and services also increases, leading to the growth of urban centers. Consequently, more people move to the cities in search of better living standards and more opportunities. This results in high population density in these areas. Therefore, the concentration of industries is a significant factor that contributes to the high population density in West African cities.

When the temperature at sea level is 10°C, what is the temperature of the air at a height of 2000 metres above sea level?
Bayanin Amsa
As a general rule, the temperature decreases by about 6.5°C for every 1000 meters increase in altitude. So, to find the temperature of the air at a height of 2000 meters above sea level, we need to calculate how many 1000 meter increments there are between sea level and 2000 meters, and then multiply that by the temperature decrease per increment. In this case, there are two 1000 meter increments between sea level and 2000 meters. So, the temperature would decrease by approximately 6.5°C x 2 = 13°C. If the temperature at sea level is 10°C, then subtracting 13°C from it gives us a temperature of -3°C at a height of 2000 meters above sea level. However, it's important to note that this is a general rule and the actual temperature at any given altitude can be affected by a variety of factors, including wind, humidity, and air pressure.

In developing countries, the most inhibiting factor for industrialization is?
Bayanin Amsa
The most inhibiting factor for industrialization in developing countries is a "monocultural economy." Monoculture refers to an economy that depends on a single product, such as agriculture or natural resources. This kind of economy is vulnerable to fluctuations in the market, changes in commodity prices, and other external factors. Countries with a monocultural economy have a limited range of economic activities, making it difficult for them to develop industries and become self-sufficient. In contrast, a diversified economy that includes various industries and sectors is more resilient and can better withstand economic shocks.

The column of ocean water moving from a low to a high latitude is described as a?
Bayanin Amsa
The column of ocean water moving from a low to a high latitude is described as a cold ocean current. Cold ocean currents are characterized by the movement of cold water from high to low latitudes, from the poles towards the equator. These currents are formed as a result of the cooling of surface waters in high latitudes. As the water cools, it becomes denser and sinks to the ocean floor, resulting in a flow of water towards the equator. Cold ocean currents have a significant effect on the climate of regions they pass through, as they cool the air above them, leading to lower temperatures and reduced precipitation.
