The correct answer is: d) All of the above.
Soil erosion is the process of soil being removed from the land by the action of wind or water. It is a major problem in Tamil Nadu, especially in areas with sloping terrain, deforestation, and intensive agriculture.
Sloping terrain is more susceptible to soil erosion because the water and wind have a greater force to carry away the soil. Deforestation removes trees, which help to hold the soil in place. Intensive agriculture can also lead to soil erosion, as the soil is disturbed by tillage and the plants are not able to grow deep roots to hold the soil in place.
Soil erosion can have a number of negative consequences, including:
- Loss of topsoil, which is the most fertile layer of soil
- Reduced crop yields
- Increased flooding and sedimentation
- Damage to infrastructure
- Loss of biodiversity
There are a number of things that can be done to prevent soil erosion, including:
- Planting trees and other vegetation
- Using conservation tillage practices
- Reducing the amount of runoff water
- Stabilizing slopes
- Protecting streambanks
Soil erosion is a serious problem, but it is one that can be prevented. By taking steps to protect our soil, we can ensure that it is available for future generations.
