1. Weathering
2. Afforestation
3. Soil Erosion
4. Soil Reclamation

Q. Which of the following statements is/are true with reference to soil erosion?

1. Deforestation exposes land to the forces of wind and water leading to loss of topsoil and nutrients.
2. Logging of forests protects the ground from soil erosion.
3. Overgrazing reduces the ability for plants to grow and water to penetrate leading to loss of soil microbes.
4. The overuse of pesticides changes the soil composition and disrupts the balence of micro-organisms in the soil.

Q.

Explain the role of plants in checking soil erosion.

Q. Which of the following statements is/are true?

1. Sheet erosion involves removal of thin layers of soil one after another, caused by running water, over a period of time.
2. When the running water cuts through the clayey soils and makes deep channels known as Gullies, it is gully erosion.
