Answer:
1. The three layers of soil are topsoil, subsoil and the parent rock
2. The four types of soil are Sand, Silt, Clay and Loam.
3. Soil erosion is the natural process in which the topsoil of a field is carried away by physical sources such as wind and water.”
In this process, the soil particles are loosened or washed away in the valleys, oceans, rivers, streams or far away lands. This has been worsening due to human activities such as agriculture and deforestation.
Soil erosion is a continuous process that occurs either slowly or at an alarming rate. It results in a continuous loss of topsoil, ecological degradation, soil collapse, etc.
