• A. Both S1 and S2 are true.
• B. Only S1 is true.
• C. Only S2 is true.
• D. Both S1 and S2 are untrue.

Answer 1

The correct option is B Only S1 is true.

Sheet and gully are the most common types of soil erosion. Sheet erosion is the removal of the top-most layer of the soil by running water over a period of time. Sometimes, the running water makes deep channels through running water called gullies. This leads to gully erosion.

Incorrect farming methods by humans lead to soil erosion. Up and down ploughing is an example of an incorrect farming method. In this method, the land along the slopes are ploughed in an up and down manner. This leads to the formation of channels for quick flow of water, which causes soil erosion.
