Which of the following is not most suitable in chain survey?

Bayanin Amsa

answer is 4, all other options are wrong because they are not too suitable for chain survey to their land forms(topography)
Plain topography is the most suitable in chain survey because in chain survey, the only instruments required are a pair of compass and a scale rule. On the plain topography there is no bend or contour which makes the setting of compass easy and chain throwing not be stressful

Settlements where the people build their houses along routes are often called

Bayanin Amsa

Settlements where people build their houses along routes are often called linear settlements. In these settlements, houses are built along a road or other linear feature, such as a river or railway line. This type of settlement pattern is common in areas where transportation routes, such as roads or rails, are the main means of access to resources and markets. Linear settlements are often found in rural areas, but can also be found in urban areas where transportation routes are well-developed. The main advantage of linear settlements is that they make transportation and communication easier, as all the houses are located along a single route.

The export trade of Mali is based mainly on

Bayanin Amsa

The export trade of Mali is based mainly on cotton. Cotton is a major cash crop in Mali and accounts for a significant portion of the country's exports. It is grown in various regions of the country, including Sikasso, Kayes, and Koulikoro. The cotton sector is an important source of income for small-scale farmers, who make up the majority of Mali's population. The cotton industry also provides employment for thousands of people in Mali, including those involved in the production, processing, and transportation of cotton. In recent years, efforts have been made to diversify Mali's exports and reduce the country's dependence on cotton, but it remains the most important export commodity.

Large scale urban migration began as a result of

Bayanin Amsa

Urban migration, or the movement of people from rural areas to cities, began as a result of industrial development. The growth of factories and industries in cities created job opportunities, attracting people from rural areas who were seeking better economic prospects. The presence of factories and industries also led to the development of other urban facilities and services, making cities more attractive places to live. As a result, people began moving to cities in large numbers, leading to the growth of urban populations and the development of large cities.

They are very expensive to construct, they are not flexible spillage can occur in cause of damage. These are the demerits of what type of transport?

Bayanin Amsa

The transport type being described in the question is pipelines. Pipelines are not flexible and can be very expensive to construct. They are typically made of metal and can be damaged by environmental factors or accidents, leading to spillage. Pipelines are commonly used to transport oil, gas, and other liquids over long distances. While they can be an efficient and safe mode of transport, their inflexibility and potential for damage can be considered as demerits.

Which of the following is a warm current?

Bayanin Amsa

The warm current among the given options is the Florida current. A current is a continuous flow of water in the ocean that moves in a particular direction. Warm currents carry warm water from the equator towards the poles, while cold currents carry cold water from the poles towards the equator. The Florida Current is a warm ocean current that flows from the Gulf of Mexico through the Straits of Florida and into the Atlantic Ocean. It is a part of the Gulf Stream system and carries warm water from the tropics up along the eastern coast of the United States. The other three options, the Labrador current, the California current, and the Benguela current, are all examples of cold currents. The Labrador current is a cold current that flows from the Arctic Ocean southward along the coast of Labrador and Newfoundland. The California current is a cold current that flows southward along the western coast of the United States. The Benguela current is a cold current that flows northward along the western coast of southern Africa.

A woman living on Longitude 30oE is carrying her body to the hospital around 1 am on Monday. Calling her husband on plane who is on 30oW, when will the husband pick the call

Bayanin Amsa

30oE + 30oW = 60o, 1hour = 15o, therefore 60o gives 4 hours which means both are 4 hours interval. In time calculation, the west love an hour at every step which the est gains an hour. The wife is carrying the baby and calling the husband at 30oE, 1 am, so the husband at the west will loose an hour at every step.
1 am before 12 midnight, westward minus 3 hours gives 9 pm in Sunday. Therefore, the wife calls on Monday while the husband receives the call on Sunday at 9 pm.

Deforestation occurs when one of the following happens except

Bayanin Amsa

Shifting cultivation occurs when a piece of land is left fallow for a while, mostly within a farming season for cultivation to be done on another piece of land. That has no damaging effect on the forest.
When trees are cut down for agricultural purposes, timber production and during excessive bush burning and grazing, the forest is often lost or reduced as there will be reduction in the numbers of trees available.
This often lead to erosion and desert enroachment

The greatest advantage of road transport over other types of transportation is that it

Bayanin Amsa

The greatest advantage of road transport over other types of transportation is its flexibility. Road transport allows for easy access to almost any location, including remote areas, and can reach places where other modes of transport cannot. It also allows for flexible routing and scheduling, meaning that goods can be transported according to the specific needs and requirements of the shipment. This makes road transport particularly well-suited for just-in-time delivery and other time-sensitive operations. While other modes of transport may be more suitable for certain types of cargo or for longer distances, the flexibility of road transport makes it an important part of the global logistics and transportation network.

The area marked D is

Bayanin Amsa

The area marked D on the map is the Sudan Savanna. It is a transitional zone between the Sahel and the Guinea Savanna, characterized by grassland and scattered trees. The Sudan Savanna receives more rainfall than the Sahel but less than the Guinea Savanna, and as a result, it has a mix of grasses and trees. The Sudan Savanna covers a large part of West Africa, including countries such as Ghana, Nigeria, Burkina Faso, and Mali.

Africa is bounded in the North by

Bayanin Amsa

Africa is bounded in the North by the Mediterranean Sea. The Mediterranean Sea is a large body of water that is connected to the Atlantic Ocean, located between Europe to the north and Africa to the south. It is bordered by several countries including Spain, France, Italy, Greece, Turkey, and Egypt, among others. The Mediterranean Sea is an important part of Africa's geography and history, as it has played a major role in the development of trade and culture in the region.

One of the following is the most correct in regards to desert erosional landforms

Bayanin Amsa

Among the given options, "Yardang" is the most correct desert erosional landform. A yardang is a long, narrow, and steep-sided ridge of rock that has been eroded by wind abrasion and deflation. These features typically form in regions with a consistent wind direction and where the rock is composed of a variety of hard and soft layers. As the wind blows across the landscape, it erodes away the softer rock layers, leaving behind the harder layers in a ridge-like shape. On the other hand, a Barchan is a crescent-shaped sand dune formed by wind action, typically found in deserts. Loess, on the other hand, is a type of sedimentary deposit that is made up of silt-sized particles, usually found in areas where wind has deposited the sediment. Self dunes are smaller, isolated dunes that form due to localized wind activity. Therefore, among the given options, only Yardang is a desert erosional landform.

The action of wind in a desert include the following except a

Bayanin Amsa

The action of wind in a desert does not include glaciation. Glaciation is a geological process that involves the erosion and transportation of materials by glaciers, which are huge masses of ice. Since glaciers require extremely cold temperatures, they cannot exist in deserts, which are known for their hot and dry conditions. On the other hand, the other three options - abrasion, attrition, and deflation - are all common forms of wind erosion that can shape the landscape in desert environments. Abrasion refers to the grinding or scraping of rocks and other materials by blowing sand or other particles. Attrition refers to the wearing down of rocks and other materials through collisions with each other. Deflation refers to the lifting and removal of loose particles, such as sand and dust, from the surface of the ground by wind.

Cirrus make up the high cloud and it is composed of ice-crystals, white and wispy. High clouds are cloud whose highest is between 6,000 m to 12,000m above the earth surface.

Stratus is one of the layers that make up the low cloud, altostratus is composed of water droplets partially covering the sky and it is also a part of middle cloud

Alto cumullus is also a distinct part of the middle cloud characterized by water droplets in layers with flattered bases in lines.

The high cloud is made up of three distinct parts which are cirrus, cirrocumulus, cirrostratus

At least 70% of Nigerian total rubber production comes from

Bayanin Amsa

The state in Nigeria that produces at least 70% of the country's total rubber production is Delta State. Rubber is an important agricultural commodity in Nigeria, and it is mostly grown in the southern parts of the country where the climate and soil are suitable for its cultivation. Delta State, located in the Niger Delta region of Nigeria, is one of the major rubber producing states in the country. The state is known for its vast rubber plantations, which are cultivated by both smallholder farmers and large agribusinesses. The climate and soil in Delta State are ideal for rubber cultivation, and this has made the state a hub for rubber production in Nigeria. While Ogun State, Ondo State, and Cross River State also produce rubber, they do not contribute as much as Delta State to Nigeria's total rubber production. Therefore, it can be concluded that Delta State is the state that produces at least 70% of Nigeria's total rubber production.

Which of the following set of cities have been developed specifically as the seat of power

Bayanin Amsa

The set of cities that have been developed specifically as the seat of power are Abuja, Brasilia, and Canberra. Abuja is the capital city of Nigeria and was chosen to replace Lagos as the capital in 1991 due to its central location, which made it a more neutral location for Nigeria's diverse population. The city was specifically designed to be the administrative center of the country with government buildings, embassies, and international organizations all located there. Brasilia is the capital city of Brazil and was built in the 1950s to replace Rio de Janeiro as the capital. The city was designed by urban planner Lúcio Costa and architect Oscar Niemeyer with a modernist style that emphasized the idea of progress and the future. Brasilia is home to the country's government institutions and serves as the center of politics and power in Brazil. Canberra is the capital city of Australia and was established in 1913 as a compromise between the two largest cities in Australia, Sydney and Melbourne, which both wanted to be the capital. Canberra was specifically designed to be the capital, with government buildings and institutions located there, as well as many national monuments and museums. Chicago, Ruhr, Kurosioro, New Delhi, and Culcutta were not specifically developed as the seat of power. While they may have important government buildings or institutions located there, they were not designed with the specific purpose of being the administrative center of their respective countries or regions.

Balance of payment in international trade does not favour developing countries because

Bayanin Amsa

The answer is 2 Most of their export are raw materials, Developing countries often depend on the developed countries to produce their raw material into finished product hence they tend to pay more when raw materials are processed and imported back. Bargaining power has little or no effect on international trade as most international deals with exchange of product. African countries most cases request for manufactured goods they needed rather than been paid

The circulatory movement of water in the ocean which is continuous is

Bayanin Amsa

A wave is a continuous movement on water surface, usually in the ocean. Its is also said to be a moving ridge on the surface of the water.

Option 1, ripples often occur on the surface of small liquids or a small body of water

Option 2, currents is a continuous movements of water in one direction. When there is water erosion, the eroded water tends to move in a particular direction, that is an example of a current.

Tsunamis is a large oceanic wave caused by an earthquake under the sea. The question says circulatory movement of surface water which is continuous in the ocean, current, ripples and tsunamis are wrong as they do not fit as the right answer.

One of the following instruments is used in measuring the direction of wind

Bayanin Amsa

A wind vane is used in measuring the direction of wind. A wind vane is a simple device that consists of a flat, light-weight plate attached to a pivot point, which is mounted on a tall pole or tower. As the wind blows, it moves the plate, which points in the direction from which the wind is coming. This makes it easy to determine the direction of the wind, which can be useful for weather forecasting, wind energy production, and other applications.

Out of the countries you listed: - Guinea is a member state of ECOWAS. - Kenya is NOT a member state of ECOWAS. - Namibia is NOT a member state of ECOWAS. - Algeria is NOT a member state of ECOWAS. So, only Guinea is a member state of ECOWAS.

The chronological order of these mining activities is

Bayanin Amsa

The correct chronological order of these mining activities is: Exploration → Exploitation → Refining → Transportation 1. Exploration: This is the initial step in mining where the potential mining site is identified, and surveys are conducted to assess the quality and quantity of minerals present in the area. 2. Exploitation: After identifying the site, the mining company starts the process of extracting the minerals from the earth. This is usually done by drilling or blasting the rocks to extract the minerals. 3. Refining: Once the minerals have been extracted, they are processed to remove impurities and obtain the desired mineral product. Refining involves various chemical and mechanical processes, depending on the type of mineral. 4. Transportation: After refining, the minerals are transported to the final destination where they will be used. This can involve shipping the minerals overseas or transporting them by truck or train to local factories for further processing. Therefore, the correct chronological order of these mining activities is Exploration → Exploitation → Refining → Transportation.

Bayanin Amsa

A line on a map or chart connecting areas of equal rainfall is called an "isohyet." It's a type of line that is used in meteorology and climatology to show the distribution of precipitation or rainfall over an area. The word "isohyet" comes from Greek, where "iso" means equal and "hyetos" means rain. So, an isohyet shows areas that receive equal amounts of rainfall.

The flow of a river at the lower course is slow because

Bayanin Amsa

The flow of a river at the lower course is slow because the gradient is greatly reduced. The gradient of a river refers to the slope or steepness of the riverbed. At the upper course of a river, the gradient is generally steep, which means that the river is flowing downhill quickly. However, as the river moves towards the lower course, the gradient decreases, causing the river to slow down. This is because the river has deposited much of its sediment, which has built up the riverbed and created a gentler slope. Additionally, the volume of water in the river also increases as it moves towards the lower course, which can also contribute to a slower flow. The increased volume means that the river has more water to move, and therefore it takes more time for the water to flow through the channel. In summary, the slow flow of a river at the lower course is due to the combination of a reduced gradient and an increase in the volume of water.

The Ruhr valley of West Germany is noted for

Bayanin Amsa

The Ruhr valley of West Germany is noted for its iron and steel industries. The region has been a major industrial hub since the 19th century, with a wealth of coal and iron deposits that made it possible to produce large quantities of steel. The Ruhr valley has been an important center of heavy industry in Germany and Europe, with many factories and steel mills located in the region. The steel industry has been a major driver of the economy in the area, providing jobs and contributing to the growth and development of the region. Today, the Ruhr valley remains an important center of steel production and other heavy industries, as well as a cultural center with a rich history and many attractions for visitors.

Which of the following belongs to the upper course of river.

Bayanin Amsa

A V-shaped valley belongs to the upper course of a river. The upper course of a river is where the river first starts to flow and is characterized by steep, narrow valleys with fast-flowing water. As the river continues to flow, it begins to erode the sides of the valley and create a V-shape as it cuts deeper into the land. Over time, the river may also create meanders, which are curved sections of the river that form as the water erodes the outer banks and deposits sediment on the inner banks. An ox-bow lake can form when the river erodes the outer banks of a meander so much that it creates a new channel, leaving the old channel to become a lake. Artificial embankments are man-made structures built to control the flow of a river, typically for flood protection or irrigation purposes.

Use the map below to answer the question that follows:
The area marked M is good for the cultivation of

Bayanin Amsa

Based on the map, the area marked "M" is located in a tropical region with high humidity and temperatures. This type of climate is suitable for the cultivation of crops such as groundnuts and raffia palm. Groundnuts are a type of nut that grows underground and are commonly grown in tropical regions, while raffia palm is a type of palm tree that is also well-suited to grow in tropical climates. Cotton and millet, on the other hand, are typically grown in regions with lower temperatures and lower humidity. In conclusion, the area marked "M" is most suitable for the cultivation of groundnuts and raffia palm due to its tropical climate.

A simple measure of the number of dependants that each 100 people in the productive years must support is

Bayanin Amsa

The simple measure of the number of dependents that each 100 people in the productive years must support is called the "dependency ratio." The dependency ratio is a ratio that compares the number of dependent individuals, such as children or elderly people, to the number of working-age individuals in a population. The working-age population is typically defined as individuals between the ages of 15 and 64 years old. For example, if there are 50 dependent individuals for every 100 working-age individuals, the dependency ratio would be 50:100, or 50%. This means that each 100 people in the productive years must support 50 dependents. The dependency ratio is an important measure for understanding the financial and economic burden that dependent individuals can place on the working-age population. It is often used by policymakers to help plan for social security, healthcare, and other services that are necessary for the well-being of a population.

Which of the following is the primary stage in the formation of an ox-bow lake?

Bayanin Amsa

The primary stage in the formation of an ox-bow lake is a meander. A meander is a bend or curve in a river's course, and over time, the force of the water erodes the outer bank of the bend and deposits sediment on the inner bank. As the process continues, the meander becomes more pronounced, and the distance between the outer and inner banks becomes greater. Eventually, the river erodes through the narrow strip of land, called the neck, that separates the meander from the main channel. This creates a new, straighter channel for the river, leaving behind a U-shaped lake that is no longer connected to the main channel. This U-shaped lake is known as an ox-bow lake. So, the meander is the primary stage because it is the initial bend in the river that begins the process of erosion and deposition that eventually leads to the formation of an ox-bow lake.

One of the following properties of soil can be easily observed in the field

Bayanin Amsa

Texture of soil is the easily observable property in the field. Texture refers to the size and composition of soil particles and can be felt by touch. For example, if soil feels gritty, it probably has a lot of sand particles, while if it feels smooth, it probably has a lot of clay particles. Knowing the texture of soil can give an indication of its fertility and other properties, such as water-holding capacity and permeability.
