Question

what is soil erosion? how do human activities and natural forces cause soil erosion? suggest some measures of soil conservation in hilly areas and desert areas

Answer 1

the process of losing the top layer of soil which is fertile and also use ful for farming is called soil erosion

Human activities such as deforestation leads to cutting of trees which causes soil erosion as roots binding the soil gets removed. And natural forces such as tsunami, tornado, high wind velocity and local water bodies cause gully erosion and sheet erosion which leads to removal of thin sheet of soil (in gully erosion by creating gullies and ravines).

Practices like strip cropping and terrace farming can be taken out to prevent soil erosion in hilly areas.

Hope it will help you!!!!
