The farming practice of contour plowing prevents major erosion effects known as?

Question

a. gullying

b. sheet erosion

c. mass movement

Answer 1

gullying letter a.

Answer 2

A. Gullying

Gullying occurs when large amounts of soil are washed down a hill or slope. Contour plowing helps to prevent this by plowing across or around the hill, stopping water from rushing straight down.

Answer 3

Clearly, contour plowing if it is successful will prevent gullying and reduce sheet erosion.

If it fails, as in it holds a lot of water in a monsoon soaked grade, the whole field can start moving downhill, so it is not c.

If the contour is off, just a bit, so that water starts to move sideways across the hill, it can cause major gully erosion when the water bursts out and runs down the grade. The precision of contour layout may need to be perfect.
