Why is a rain drop a particularly damaging element to soil

Answers

Answer:

Raindrops are very effective in the removal of the topsoil. During rainfall, the raindrops strike the surface of the soil, as a result of which the soil particle are broken apart and are washed away from that place dislocating its nutrient particles that favors the growth and expansion of the plants. In simple words, it leads to the removal of the top soil, thereby losing the fertility of the soil.

Thus, raindrops are particularly damaging elements to the soil.
A rain drop can be a damaging element to soil because it can cause erosion due to the soil dislodging from the rain drops.
