What is meant by soil erosion? What are its various causes and harms? How can it be checked? In which areas is soil erosion more severe?

Answer:

The removal of land surface or the topsoil by water, wind or ice is known as soil erosion.                      Plant roots firmly bind the soil. In the absence of plants, soil becomes loose. So it can be easily moved by wind and flowing water.                                                                                                                            For preventing soil erosion, deforestation and cutting of trees should be prevented and efforts should be made to increase the green area. Erosion of soil is more severe in areas of little or no surface vegetation, such as deserts or barren lands.
