In India, the problem of soil erosion is associated with which of the following? 1. Terrace cultivation 2. Deforestation 3. Tropical climate Select the correct answer using the code given below.
Explanation
1. Terrace cultivation: This is a soil conservation technique used on sloping land. It involves creating leveled steps or terraces to reduce water runoff and soil erosion.
2. Deforestation: When trees are cut down, the soil loses the protection provided by their roots. This exposes the soil to wind and rain, making it more susceptible to erosion. Deforestation is a major driver of soil erosion in India.
3. Tropical climate: While heavy rainfall in tropical regions can contribute to soil erosion, it's not the sole factor. Deforestation and poor land management practices exacerbate the issue.
Thus, the correct answer is '2 only'.
