Answer Details
The best technique to prevent soil erosion in a humid, gently sloping area is contour ridging. Contour ridging involves creating ridges that run along the contour lines of the slope, which helps to slow down the flow of water across the surface of the soil. This technique helps to trap water, reduce its speed, and allow it to penetrate into the soil. By reducing the speed of water, contour ridging also helps to reduce the amount of soil that is carried away by the water, which reduces erosion. Terrace cultivation and intercropping can also be effective techniques for reducing erosion, but they are generally better suited to steeper slopes. Wind breakers can help to reduce erosion caused by wind, but they are not as effective for preventing erosion caused by water. In summary, contour ridging is the best technique for preventing soil erosion in a humid, gently sloping area because it helps to slow down the flow of water and reduce erosion, and it is well-suited to this type of terrain.
Question 5 Report
If M is due west of station N, the bearing of M from N is
Answer Details
If M is due west of station N, it means that M is directly to the left of N when you are facing North. In terms of bearings, due west corresponds to a bearing of 270°. To understand why, imagine standing at station N and facing North. You can think of bearings as angles measured in a clockwise direction from North. A bearing of 0° would correspond to due North, a bearing of 90° would correspond to due East, and so on. Since M is due west, it is directly to your left when you are facing North, which means it is 90 degrees to your left. If you add 90° to the 180° bearing of due South, you get 270°, which is the bearing of M from N. So, the correct answer is 270°.

Question 19 Report
Which of the following is most influential in the location of textile and footwear industries?
Answer Details
Among the options given, the most influential factor in the location of textile and footwear industries is abundant cheap labor. Textile and footwear industries require a large labor force to produce goods at a low cost. If a country has a large supply of labor willing to work for low wages, it can attract textile and footwear industries to set up factories in its territory. This is because labor is usually the largest cost for these industries, and a country with cheap labor can offer cost advantages to manufacturers. Raw materials are also important for these industries, but they can be imported from other countries if they are not available locally. Energy supply and low interest rates may also affect the cost of production, but they are less critical factors than the availability of cheap labor. In summary, countries with a large supply of cheap labor have an advantage in attracting textile and footwear industries because they can offer low production costs to manufacturers, making their products more competitive in the global market.

Answer Details
A river that enters the sea at a gently inclined costal plain where tidal waves are weak will most likely develop into a delta. A delta is a landform that is formed when a river deposits sediment at its mouth where it meets the sea. The sediment builds up over time, creating a triangular-shaped area that extends into the sea. The gently inclined costal plain and weak tidal waves allow the sediment to accumulate and build up the delta over time. This process can lead to the creation of new land, making the delta a valuable area for agriculture and human settlement.

Answer Details
The Stevenson's screen is a box used to house weather instruments that measure temperature, humidity, and other meteorological variables. It is raised about one meter above the ground to avoid the heat from the ground. When the screen is placed on the ground, it can absorb and radiate heat from the ground, which can affect the accuracy of temperature measurements. By raising it one meter above the ground, the screen is more exposed to the free atmosphere and less affected by the heat from the ground. Additionally, raising the screen helps to reduce the impact of raindrops entering the instruments during heavy rainfall. The height also helps to avoid the effects of nearby trees and other obstacles that could affect wind flow around the instruments and affect the measurements. Therefore, the main reason for raising the Stevenson's screen one meter above the ground is to ensure that the weather instruments inside are measuring the temperature and other meteorological variables accurately and without interference from external factors.
Question 29 Report
In river transport, the problem of irregular levels of water can be overcome by
Answer Details
One way to overcome the problem of irregular levels of water in river transport is by building locks and canals. Locks are structures that allow boats and ships to pass from one water level to another. They work by closing and filling with water, which raises or lowers the water level inside the lock to match the water level on the other side. This allows boats and ships to safely navigate through areas where the water level is different. Canals, on the other hand, are man-made waterways that are built to connect two waterways or to bypass a stretch of river with difficult navigational conditions. By providing a controlled and stable water environment, locks and canals can greatly improve the reliability and efficiency of river transport.

A weather element controlled mainly by latitude is
Answer Details
Temperature is the weather element that is controlled mainly by latitude. Latitude is a measurement of how far a place is from the equator, with the equator being at 0° latitude and the poles at 90° latitude. The closer a place is to the equator, the more direct sunlight it receives, and the warmer it tends to be. The further away from the equator a place is, the less direct sunlight it receives and the cooler it tends to be. This is why the tropics are warm and the poles are cold. So, in simple terms, latitude mainly affects temperature because it determines the amount of direct sunlight a place receives, which in turn affects its overall temperature.
