Which method best helps to prevent wind erosion? rotating crops
decreasing riverbank slopes
growing more vegetation
avoiding soil compaction

Growing more vegetation

Explanation:

Soil erosion by wind occurs anywhere when vegetation and climatic conditions are conducive. These conditions include presence of very strong winds and when the soil is loose, dry, and is composed of fine granulated particles.

It also occurs when the soil surface is relatively smooth and there is sparse or no vegetative. It can also occur where there are large fields with no windbreak mechanisms in place.

The best way to reduce wind erosion is to keep the wind off the soil surface by covering the soil surface. This involves growing of more vegetation, either cash crops or cover crops which serves to protect the soil and keep the winds higher off the surface.

Also trees can be planted around the farms to serve as wind breaks which breaks or reduces the force of the winds.

Also, soil compaction which is the process of increasing the density of soil by packing the soil particles closer together causing a reduction in the volume of air can help to prevent wind erosion.

From the given options above, the best option would be growing more vegetation.

Practicing crop rotation serves to preserve soil nutrients and prevent diseases.

Decreasing riverbank slopes prevents erosion by water.

Avoiding soil compaction would lead to more erosion by wind.
