Choose all the answers that apply.

Erosion can be reduced by:

1. contour plowing
2. putting up fences
3. planting trees
4. removing topsoil

Answer 1

The answer will be #3 and #4

Step-by-step explanation:

Because the more the organisms live in the topsoil the weaker the soil would get and most likely that would happen and planting trees stop soil erosion because when the trees absorb water underground it makes the soil firm and tight just like the (abnormal) soil you would see near few feet near most trees.
