Answers
Answer:
Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans
Following steps are taken to control the soil erosion in hilly areas:
(i) Contour ploughing: this refers to ploughing along contour lines.
(ii) Terrace farming: construction of steps along the hilly areas by cutting the rock layers to reduce the flow of rivers.
(iii) Plugging of gullies to prevent gully erosion.
Answer:
Soil erosion is the natural process in which the topsoil of a field is carried away by physical sources such as wind and water.
The following are the important steps taken to control soil erosion in hilly areas:
1. Afforestation: The best way to conserve soil is to increase the area under forest. Indiscriminate felling of the trees should be stopped and efforts should be made to plant trees in new areas.
2. Checking shifting cultivation: Checking and reducing shifting cultivation will reduce soil erosion.
3. Contour Ploughing: If ploughing done at right angles to the hill slope, following the natural contours of the hill, the ridges and furrows break the flow of water down the hill. This will prevents soil erosion.
