Question

mention two methods to prevent soil erosion.​

Answer 1

(1) Afforestation (Planting trees)

(2) Don't graze cows or any other animal on the land

Answer 2

Here's ur answer....

Plant grass and shrubs. Bare soil is easily swept away by wind and water, the two main causes of erosion. Plant roots hold the soil together, while their leaves block rain and stop it breaking the soil apart.[1] Turf, ornamental grass, and low, spreading shrubs work best since they cover the soil completely.

If you have any bare ground, try to establish plant cover as soon as possible to limit erosion.

If the ground is mostly flat (slope of 3:1 or less), this might be enough to solve the problem.[2] Steep slopes erode faster, so they need more protection.
