What is soil erosion? Mention two steps that could be taken to prevent soil erosion.
उत्तर
The removal of the topsoil by water, wind and human activities is called soil erosion.
Two ways to prevent soil erosion are
- Shelterbelts: Trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind.
- Constructing dams: Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.
