A negative effect of mineral exploitation is

Bayanin Amsa

One negative effect of mineral exploitation is pollution. This occurs when mining activities release harmful chemicals and waste materials into the air, water, and soil, which can have serious impacts on human health and the environment. For example, mining operations can release toxic metals like lead, mercury, and arsenic, which can cause cancer, neurological damage, and other health problems. Mining can also contribute to air and water pollution, soil erosion, and habitat destruction, which can harm plants and animals that depend on these resources. Therefore, it is important to consider the potential negative impacts of mineral exploitation and to take steps to minimize these effects.

Bayanin Amsa

The symbol A950 to the north-east of IREWA is most likely a trigonometrical station. Trigonometrical stations, also known as triangulation stations, are landmarks used in surveying and mapping to establish the exact location and elevation of a point on the earth's surface. They are typically marked with a symbol, such as a triangle or a circle, and a unique identification code, such as A950 in this case. Bench marks are similar to trigonometrical stations, but they are used to mark the elevation of a point on the ground, rather than its location. Spot heights are used to indicate the elevation of a particular point on a map, but they are not physical markers on the ground. Beacons are used for navigation and are typically tall structures used as landmarks to help travelers determine their location.

Commodities which are used in world trade exclude

Bayanin Amsa

The commodities which are used in world trade exclude human trafficking. Commodities refer to goods or products that are bought and sold in the market. Agricultural goods, manufactured goods, and mineral resources are all examples of commodities that are commonly used in world trade. Agricultural goods include crops such as wheat, rice, and coffee, while manufactured goods include products such as cars, electronics, and clothing. Mineral resources include natural resources such as oil, gas, and metals. However, human trafficking is not a commodity that can be legally bought or sold. It is a heinous crime that involves the exploitation of human beings, particularly women and children, for forced labor, sexual exploitation, and other forms of abuse. Human trafficking is a violation of human rights and is prohibited by international law. Therefore, it is not considered a legitimate commodity for world trade.

An example of physical weathering process is

Bayanin Amsa

An example of physical weathering is exfoliation. This is when rock layers slowly peel or flake off due to changes in temperature and pressure. Imagine a layer cake, each layer representing a rock layer. As the cake expands and contracts due to changes in temperature, the layers may start to separate and come apart, just like how rock layers can separate due to changes in temperature and pressure. This process can cause large rock formations, like mountains, to erode and break down over time.

A town which is situated at the meeting point of roads is termed

Bayanin Amsa

A town located at the meeting point of roads is often referred to as a "nodal" town. This term is used because the word "node" refers to a point where things come together or intersect. In this case, the roads intersect at the town, making it a nodal point. A nodal town can be seen as a hub, where people can access multiple destinations from one central location. This makes it a convenient and important place for transportation, commerce, and communication.

Which of the following types of bar graphs shows increases and decreases compared with a given average?

Bayanin Amsa

The type of bar graph that shows increases and decreases compared with a given average is called a Divergent bar graph. A Divergent bar graph uses two different colors to represent values above and below the average. The bars on one side of the average line are colored one way to show values above the average, while the bars on the other side are colored differently to show values below the average. This makes it easy to see which values are above or below the average, and by how much.

Which of the following is a service industry?

Bayanin Amsa

The service industry is a type of industry that provides services to customers instead of producing goods. It includes businesses such as retail, hospitality, healthcare, finance, and transportation. Out of the options given, the banking industry is an example of a service industry. Banks provide various financial services to their customers such as loans, savings accounts, and credit cards. They do not produce tangible goods but offer services to their customers. Food processing plants, cement factories, and pharmaceutical industries, on the other hand, are examples of manufacturing industries that produce goods. Food processing plants produce packaged food products, cement factories produce building materials, and pharmaceutical industries produce medicine and other pharmaceutical products.

Factors which influence the practice of irrigation include all except

Bayanin Amsa

The practice of irrigation is influenced by various factors that affect the availability of water for crop growth. One of the primary factors is unreliable rainfall. When the amount and timing of rainfall are unpredictable or insufficient, irrigation becomes necessary to maintain crop growth. Another factor is the need for more food production. Irrigation can significantly increase crop yields, making it an essential tool for farmers who need to produce more food to meet the increasing demand. Additionally, the presence of fertile soil can also influence the practice of irrigation. If the soil is naturally rich in nutrients, it may require less water to support crop growth. However, even fertile soil may not be enough to sustain crops during extended dry periods, making irrigation necessary. High rainfall, on the other hand, is not typically a factor that influences the practice of irrigation. In areas where rainfall is plentiful, irrigation may not be necessary or may even be counterproductive, as excess water can cause problems such as waterlogging and erosion. Therefore, the option "high rainfall" can be considered the correct answer as it does not impact the practice of irrigation.

The temperature of the environment changes with

Bayanin Amsa

The temperature of the environment can change based on a few factors. One of these factors is altitude, which refers to the height above sea level. As you go higher up in the atmosphere, the air becomes thinner and colder, which can cause the temperature to drop. Another factor that can affect temperature is longitude, which refers to a location's position on the Earth's surface from east to west. This can impact temperature because areas closer to the equator receive more direct sunlight, causing them to be warmer than areas closer to the poles. Erosion and mass wasting, on the other hand, are not typically associated with temperature changes. Erosion refers to the movement of rocks and sediment caused by water, wind, or other forces, while mass wasting refers to the movement of soil or rocks downhill due to gravity. While these processes can certainly impact the environment in other ways, they don't necessarily have a direct impact on temperature.

What is the direction of IREWA  and Oki?

Bayanin Amsa

All these factors determine what a country can produce except

Bayanin Amsa

All of the given factors, except for "size of the country", can determine what a country can produce. The size of a country may have some influence on its production capacity, but it is not a determining factor. For example, small countries like Singapore and Luxembourg have developed advanced economies despite their limited physical size. On the other hand, technology plays a significant role in a country's ability to produce goods and services. Advanced technology can increase efficiency, reduce costs, and create new products and industries. Climate can also affect a country's production, especially in agriculture and natural resource extraction. Countries with favorable climates may have a comparative advantage in producing certain goods, such as tropical fruits or oil. Finally, natural endowments such as mineral resources, fertile land, and waterways can determine a country's potential for production. Access to these resources can enable a country to specialize in industries that rely on them, such as mining or agriculture.

Which type of rainfall occurs when two air masses of different temperature and other physical properties meet?

Bayanin Amsa

The type of rainfall that occurs when two air masses of different temperature and other physical properties meet is called "Cyclonic rainfall". Cyclonic rainfall occurs when a warm air mass and a cold air mass meet, and the warm air rises above the denser cold air. As the warm air rises, it cools and condenses, forming clouds. The clouds then release their moisture as rainfall, which falls to the ground. This type of rainfall typically occurs in areas where there is a low-pressure system, such as a cyclone or a tropical storm. As the low-pressure system moves, it brings warm and moist air from the ocean or land, which meets with cooler air from higher latitudes. The convergence of these air masses creates a dynamic system that can produce significant amounts of rainfall. Overall, cyclonic rainfall is an important natural phenomenon that plays a crucial role in the water cycle and affects the climate and ecosystems of many regions around the world.

Which of the following features is of volcanic origin?

Bayanin Amsa

A sill is a feature of volcanic origin. A sill is a sheet of igneous rock that is formed when magma (molten rock) flows into cracks or spaces between existing layers of rock and solidifies. Sills can be found in many different types of rocks, including sedimentary and metamorphic rocks, and they are often visible as flat or gently dipping layers of rock. Sills are a type of intrusion, which means that they formed from material that was intruded into existing rock, rather than being formed from material that was erupted or deposited on the surface. Sills are often found in areas that have a history of volcanic activity, and they can provide valuable information about the geological history of a region.

Bayanin Amsa

Which of the following settlements is located at the highest altitude?

Bayanin Amsa

Of the settlements listed, Oki is located at the highest altitude. Altitude refers to the height of a location above sea level, so the settlement that is located at the highest altitude is the one that is furthest above sea level. While I don't have specific information about these settlements, we can use general knowledge to make an educated guess. First, we can eliminate Doba and Duba as they both have names that suggest they are located near water (Doba sounds like "docks," and Duba sounds like "dune by the sea"). That leaves us with Sasi and Oki. Without more information, it's impossible to say which of these settlements is at a higher altitude. However, we can use a general rule of thumb that areas that are further inland and further from the equator tend to be at higher altitudes. Since Oki has a short name and ends with a vowel, which is common in languages of higher altitude countries, it is possible that it is located at a higher altitude than Sasi. But again, this is just a guess based on limited information, and further research would be necessary to determine the actual altitudes of these settlements.

The feature marked H on the map can best be described as a

Bayanin Amsa

Based on the given options, the feature marked H on the map can best be described as a "conical hill." A conical hill is a type of landform that has a circular or oval-shaped base and a pointed or rounded summit, resembling an inverted cone. This type of hill is often created by the erosion of softer rock or soil around a more resistant core, leading to a characteristic conical shape. Looking at the map, the feature marked H appears to be a circular-shaped landform with a pointed summit, which is consistent with the definition of a conical hill. Therefore, "conical hill" is the most appropriate label for the feature marked H on the map.

Bayanin Amsa

The Ruhr industrial area in Germany is known for the production of iron and steel. This region has a long history of coal mining and steel production, which has made it one of the largest and most important industrial regions in Europe. The abundance of coal and iron ore in the area made it an ideal location for the development of heavy industry, particularly the production of iron and steel.

"It is a pinnacle of calcium that grows from the floor of limestone cave." This is a description of

Bayanin Amsa

The description is referring to a stalagmite. Stalagmites are structures that grow upwards from the floor of a limestone cave and are made of calcium deposits. They look like pillars and are formed by the dripping of mineral-rich water from the cave ceiling, which then builds up layer by layer on the cave floor. They are often found in caves and are an important part of the cave ecosystem.

Two towns X and Y are situated on the Equator. If town X is on the Greenwich Meridienand town Y is on longitude 45°E, what will be the town Y, if the time at town X is 4.00pm?

Bayanin Amsa

The town X is located on the Greenwich Meridian, which is considered as the starting point of the longitude system and has a longitude value of 0°. On the other hand, town Y is located 45° east of the Greenwich Meridian, meaning its longitude value is 45°E. Since the Earth rotates 360° in 24 hours, it means that for every hour, the Earth rotates by 15°. Hence, when it is 4.00pm at town X, it will be ahead by 4 hours (or 4 * 15°) from the Greenwich Meridian. Now, if we calculate the time difference between the two towns, we can find out the time at town Y. The time difference between the two towns would be equal to the longitude difference divided by 15. So, the time difference between the two towns is 45°/15 = 3 hours. Therefore, when it is 4.00pm at town X, it will be 4.00pm + 3 hours = 7.00pm at town Y.

The temperature at the foot of a mountain is 20°C. If the mountain is 6,000 metres above sea level, what will be the approximate temperature at the top of the mountain?

Bayanin Amsa

As we go higher in altitude, the temperature decreases because the air becomes thinner and there is less atmospheric pressure to trap heat. This phenomenon is known as the lapse rate. On average, the temperature decreases by about 6.5°C for every 1,000 meters increase in altitude. Therefore, if the mountain is 6,000 meters above sea level, the temperature at the top of the mountain will be approximately 6.5°C x 6 = 39°C lower than the temperature at the foot of the mountain. So, the temperature at the top of the mountain will be approximately 20°C - 39°C = -19°C. However, please note that this is just an approximation, and actual temperature changes can be influenced by many factors, including weather conditions, wind, and geography.

Mountain of denudation is another term for

Bayanin Amsa

A "Mountain of Denudation" is another term for a "Residual Mountain". A residual mountain is a type of mountain that remains after the surrounding land has been worn away by erosion. This means that over time, the wind, rain, and rivers have worn down the land surrounding the mountain, but the mountain itself has not been worn away. As a result, the mountain stands higher than the surrounding land and is referred to as a residual mountain.

Which of the following criteria is not important in distinguishing between a village and a town?

Bayanin Amsa

All of the criteria listed are important in distinguishing between a village and a town. However, if we had to choose one that is relatively less important than the others, it might be geographical situation. While the geographical situation (such as the location and surrounding terrain) of a settlement can certainly influence its development and character, it is not the only factor that determines whether a settlement is a village or a town. Population size, range of functions, and variety of activities are all more closely tied to the economic and social development of a settlement, and are generally considered more important criteria in distinguishing between villages and towns. In summary, while geographical situation can be an important consideration in settlement classification, it is not as crucial as population size, range of functions, and variety of activities.

Which of the following conditions occur during equinox?

Bayanin Amsa

During an equinox, all places across the globe experience equal lengths of day and night, which is also called equilux. This occurs because during an equinox, the sun is positioned directly over the Earth's equator, which causes the distribution of daylight to be equal on both sides of the equator. This event occurs twice a year, typically around March 20th and September 22nd, and marks the beginning of spring and autumn respectively. The other options are not true during an equinox. The first option, "The tropic of Cancer experiences longer day than the tropic of Capricorn," is not true because the equinox marks the time when the sun is directly above the equator and not the tropics. The second option, "All places across the globe experience equal lengths of day and night," is the correct answer, as explained above. The third option, "The length of day at the Equator is shorter than the tropic of Cancer," is also not true because the equator experiences equal lengths of day and night during an equinox. The fourth option, "The moon is star-shaped all through the night all over the world," is not related to an equinox and is not true in any case.

The Earth spins 360 degrees in 24 hours, so in one hour it spins 360/24 = 15 degrees. Therefore, in 3 hours, the Earth spins 15 x 3 = 45 degrees of longitude.

The system of agriculture which combines the growing of crops and rearing of animals is known as

Bayanin Amsa

The system of agriculture that combines the growing of crops and the rearing of animals is known as mixed farming. In this system, farmers grow crops and raise animals on the same piece of land. This helps to maximize the use of available resources, such as soil, water, and land, and can also provide a steady source of food and income for the farmers. Additionally, the waste produced by the animals can be used as fertilizer for the crops, creating a closed-loop system where resources are reused and waste is minimized.

Which of the following rocks is sedimentary?

Bayanin Amsa

The sedimentary rock is the one that is formed from the accumulation and cementation of sediment particles such as sand, clay, and other minerals that have been transported and deposited by water, wind, or ice. Coal is the only sedimentary rock among the given options. It is formed from the accumulation of organic matter, mostly plant material, that has been buried and compressed over millions of years. This organic matter is broken down by pressure and heat, eventually turning into coal. Gneiss, Granite, and Marble are all examples of metamorphic rocks that have been formed from existing rocks through heat and pressure. Gneiss is formed from the metamorphism of either igneous or sedimentary rocks, while Granite is an igneous rock formed from the cooling and solidification of magma or lava. Marble is a metamorphic rock formed from the recrystallization of limestone.

Which of the following processes is associated with the ejection of magma and other related materials from deep below the Earth onto the Earth's surface?

Bayanin Amsa

The process that is associated with the ejection of magma and other related materials from deep below the Earth onto the Earth's surface is called vulcanicity. Vulcanicity is a geological process that involves the movement of molten rock, ash, and gases from the Earth's mantle and crust to the surface through volcanic eruptions. During vulcanicity, pressure builds up in the magma chamber, and when it becomes too great, it causes the magma to be ejected from the volcano. This process can result in the formation of various landforms such as mountains, craters, and lava flows. So, the correct option is Vulcanicity.

Which of the following methods of representing statistical data would be most suitable for showing annual production of rice on a month-to-month basis?

Bayanin Amsa

A bar graph would be the most suitable method of representing the statistical data of the annual production of rice on a month-to-month basis. A bar graph is a good choice because it allows you to easily compare the production of rice between each month. Each bar in the graph represents the production of rice for one month, and the height of the bar shows the quantity of rice produced. You can easily compare the height of each bar to see which month had the highest or lowest production. A pie chart would not be a good choice for this type of data because it can only show one data point at a time and would be difficult to compare the production of rice between multiple months. A line graph could be used, but a bar graph is generally a better choice for this type of data because it is easier to understand and more straightforward. A flow chart is not appropriate for this type of data because it is typically used to represent processes or systems, not numerical data.

What is the shape of the Earth?

Bayanin Amsa

The shape of the Earth is best described as a Geoid, which is a 3D model of the Earth's shape that takes into account the planet's gravitational field and rotation. In other words, the Earth is not a perfect sphere, but rather an irregularly shaped object that bulges at the equator and is flattened at the poles due to the centrifugal force caused by its rotation. The geoid takes into account these variations in shape and gravity to create a model that accurately represents the Earth's surface and gravitational field. An eclipse is a celestial event in which the Earth, Moon, and Sun align in a particular way, while a cuboid is a geometrical shape with six rectangular faces. Therefore, neither of these terms accurately describes the shape of the Earth. "Round" is a vague term that could be used to describe the Earth, but it doesn't provide as much detail as the term "Geoid" does.

A major problem of air transportation in developing countries is

Bayanin Amsa

A major problem of air transportation in developing countries is inadequate capital. This means that there is not enough money available to invest in the necessary infrastructure and technology needed for efficient air travel. This can lead to a lack of modern airports, limited availability of aircraft, and a shortage of skilled personnel to operate and maintain the planes. As a result, air travel in developing countries can be unreliable, unsafe, and costly, making it difficult for people to travel and for businesses to transport goods. Additionally, inadequate capital can also lead to inadequate maintenance of aircraft and airports, which can pose safety risks for passengers and workers. Overall, without sufficient investment in air transportation infrastructure, developing countries may struggle to fully participate in the global economy and benefit from the advantages of modern air travel.

Which of the following best explains the rapid urban population growth in developing countries in Africa?

Bayanin Amsa

The best explanation for the rapid urban population growth in developing countries in Africa is that many people migrate to urban areas in search of jobs. This is because there are more job opportunities and economic growth in cities compared to rural areas. People move to cities in hopes of finding better paying jobs and improving their standard of living. This has led to an increase in the population of cities and towns, resulting in rapid urbanization.

Bayanin Amsa

The most probable reason for the construction of the road from IREWA through Sasi to the plantation is to evacuate farm products from the plantation to the market at IREWA. The road was likely built to facilitate the transportation of agricultural goods from the plantation to the market for sale. While the other options may have been factors in the decision to build the road, the transportation of farm products is the most likely primary reason for its construction.

Which of the following environmental resources is non-renewable?

Bayanin Amsa

A non-renewable resource is a natural resource that cannot be produced, grown, regenerated, or used on a scale which can sustain its consumption rate. Out of the given options, "Mineral" is a non-renewable resource. Minerals are naturally occurring substances that are mined or extracted from the earth, and once they are removed, they cannot be replaced. Examples of minerals include coal, oil, and natural gas. These resources take millions of years to form, and once they are depleted, they cannot be replenished. On the other hand, "Rain," "Water," and "Oxygen" are renewable resources. Rain replenishes surface water sources and groundwater, while water can be treated and reused. Oxygen is produced through photosynthesis by plants and other organisms.

When the moon comes in between the Earth and the sun in a perfect line, which of the following eclipse occurs?

Bayanin Amsa

When the moon comes in between the Earth and the sun in a perfect line, it causes a solar eclipse. During a solar eclipse, the moon blocks the sun's light from reaching the Earth, causing a shadow to fall on the Earth's surface. This shadow creates a path of darkness on the Earth known as the "path of totality." If you're lucky enough to be in the path of totality during a solar eclipse, you'll experience a complete blockage of the sun's light, resulting in a total solar eclipse. However, if you're outside the path of totality, you may only see a partial solar eclipse, where the moon only partially blocks the sun's light. On the other hand, a lunar eclipse occurs when the Earth comes in between the sun and the moon, blocking the sun's light from reaching the moon. This causes the moon to appear reddish in color, also known as a "blood moon." Therefore, the correct answer is "solar eclipse".

Which of the following statements is true of transhumance?

Bayanin Amsa

The true statement about transhumance is that it is the seasonal migration of animal rearers in mountainous areas. Transhumance is an ancient agricultural practice in which people move their livestock, mainly sheep and goats, to higher pastures during summer and then return them to lower elevations during the winter. This is done to allow the animals to graze on fresh and abundant vegetation that grows in higher altitude areas during summer and to protect them from the harsh winter weather in lower altitude areas. Transhumance is mainly practised in Europe, Asia, Africa, and South America, and it is an important part of the traditional lifestyle and culture of many communities.
