Question 1 Report
Temperature decreases with height in the
Answer Details
The temperature decreases with height in the troposphere. The troposphere is the lowest layer of the Earth's atmosphere, which extends from the surface up to about 7-20 kilometers depending on the location. The reason for the decrease in temperature with height in the troposphere is because the air is heated by the Earth's surface, and as you go higher, the air becomes thinner and less able to retain heat. In other layers of the atmosphere, such as the stratosphere, temperature can actually increase with height due to the presence of certain gases that absorb radiation from the sun. In the ionosphere and exosphere, the temperature can vary widely depending on the level of solar activity and other factors.

The hinterland of a port is
Answer Details
The hinterland of a port refers to the area that is served by the port. This area includes the surrounding land and communities that rely on the port for their trade and transportation needs. It can extend quite far beyond the immediate vicinity of the port itself, as goods may be transported to and from the port via various modes of transportation such as trucks, trains, and barges. Essentially, the hinterland is the region that depends on the port for access to global markets and the movement of goods.

Question 10 Report
One characteristic feature of intensive farming is that, it is practised in urban centres where
Answer Details
Intensive farming is characterized by the practice of maximizing agricultural yield by using a small amount of land and a high input of labor, capital, and technology. One common location for intensive farming is in urban centers where the human population is high. This is because there is a greater demand for food, and urban areas often have limited space for traditional farming practices. In addition, transportation costs are reduced, and fresh produce can be delivered quickly to nearby markets. Therefore, intensive farming can be an effective way to meet the food needs of urban populations.
Question 11 Report

Question 12 Report
Which of the following problems hinder international trade? I. Political instability II. Low tariffs III. Inadequate foreign exchange IV. Strained relations
Answer Details
International trade can be hindered by various factors. Out of the given options, the problems that hinder international trade are political instability, inadequate foreign exchange, and strained relations. Political instability refers to a situation where a country experiences frequent changes in government, civil unrest, or violent conflicts. This can negatively impact international trade as it creates uncertainty and risks for businesses, leading to a decrease in investment and economic growth. Inadequate foreign exchange occurs when a country doesn't have enough foreign currency to pay for imports or service its foreign debt. This can result in a shortage of essential goods and services, a decrease in investment, and a decrease in economic growth. Strained relations between countries can also hinder international trade. This can occur due to various reasons such as political conflicts, trade disputes, or diplomatic tensions. When countries have strained relations, it can lead to trade barriers, reduced investments, and a decrease in economic growth. Low tariffs, on the other hand, do not necessarily hinder international trade. In fact, they can encourage international trade as they make imported goods cheaper, leading to an increase in demand for foreign goods. Therefore, the correct answer is option D - I, III and IV only.

Question 16 Report
The mode of transportation which is best used to convey perishable good is
Answer Details
The best mode of transportation to convey perishable goods is air transportation. Perishable goods, such as fresh produce or flowers, have a short shelf life and need to be transported quickly to their destination to maintain their quality and freshness. Air transportation is the fastest mode of transportation, allowing perishable goods to reach their destination quickly and efficiently. Air transportation also has the advantage of being able to maintain a consistent temperature throughout the journey, ensuring that the perishable goods are kept at their optimal temperature and reducing the risk of spoilage. While other modes of transportation, such as road and rail, may also be able to transport perishable goods, they are generally slower and may not have the same temperature control capabilities as air transportation. Pipeline transportation, on the other hand, is not suitable for transporting perishable goods as it is typically used for transporting liquids or gases. In summary, air transportation is the best mode of transportation for conveying perishable goods due to its speed and temperature control capabilities, allowing the goods to arrive at their destination quickly and in optimal condition.
Question 17 Report
A rock in which water cannot easily pass through is termed
Answer Details
A rock in which water cannot easily pass through is called impermeable. Impermeable means that the rock does not allow liquids or gases to pass through it easily. In other words, it is a solid barrier that prevents water from flowing through it. This is different from porous, which means that the rock allows water or other liquids to pass through it easily. An aquifer is a type of rock or soil that holds water and allows it to move through it.
Question 18 Report
A great circle route is used to
Answer Details
A great circle route is used to save time and fuel by flying the shortest distance between two points on the surface of the Earth. This route follows the curve of the Earth's surface, which is a sphere, and is the shortest distance between any two points on it. Using a great circle route, airplanes can avoid flying over long distances, such as deserts or oceans, and also avoid flying near the north pole. By taking the shortest distance possible, airlines can save both time and fuel, making their flights more efficient and cost-effective.
Question 22 Report
The day in which the length of day and night are equal everywhere on Earth is
Answer Details
The day in which the length of day and night are equal everywhere on Earth is called the equinox. There are two equinoxes in a year: the March or Vernal Equinox and the September or Autumnal Equinox. During the equinox, the tilt of the Earth's axis is not pointed towards or away from the sun, resulting in equal amounts of daylight and darkness at all latitudes across the Earth. This happens because the Earth's axis is tilted by 23.5 degrees and as it orbits around the sun, different parts of the Earth receive varying amounts of sunlight. Therefore, the correct option is 21st March (March Equinox) and 22nd September (September Equinox) when the day and night are approximately equal in duration all over the world.
Question 23 Report
Which of the following features promote the development of nucleated settlement?
Question 24 Report
Which of the following is a process of river transportation?
Answer Details
Suspension is a process of river transportation. Suspension occurs when small particles such as silt and clay are carried along with the river flow. These particles are suspended in the water and move along with the current. The water can carry these particles for long distances, even across entire continents. This process is facilitated by the speed and force of the river flow. When the water moves fast enough, it can lift and carry the small particles along with it. As the river slows down, the particles start to settle and may eventually be deposited on the riverbed or along the riverbanks. Other processes of river transportation include attrition, which is the gradual wearing down of rocks and boulders as they collide with each other and the riverbed, and abrasion, which is the erosion of the riverbed by the particles being carried in the water. Deflation, on the other hand, is a process that occurs when the wind blows away loose sediment, such as sand or silt, from the riverbanks or riverbed.
