Answer 1

Answer:

Which could cause topsoil to be lost?

a) wind and water erosion

Explanation:

A natural and common cause of soil erosion is Water. Water can carry away tiny soil particles.

Raindrops can impact the soil surface and can break down the aggregates in soil and scatter them.

Water runoff is another cause of soil erosion and this occurs when water on a slope isn’t absorbed into the soil or becomes trapped on the surface.

Loose particles can be picked up and carried away by the wind.

Soil surfaces can be worn down when struck by airborne particles carried by the wind.

B. Lack of use of the top soil rather helps the top soil to regain its nutrients.

c. Compaction can the topsoil from losing particles, since there are no loose particles to be picked up.

D. Desertification mostly causes the soil to lose its nutrients, not go away completely.

Hope this helps!
