Detailed Solution

Concept- The phenomenon known as soil erosion occurs when the top layer of soil is removed, which causes the soil to deteriorate. The most rich soil is found at the top, and if it is moved, the land may become less productive.
This is a normal process that has a variety of potential causes. Both the wind and the water erode the soil. When the wind blows, the top layer of soil is gently disturbed, which leads to soil erosion.
When water permeates the soil, it erodes the top layer more quickly than the wind and is the main factor in soil erosion. Sand and rocks both do not contribute to soil erosion.
Hence, the correct answer is option 1.
