Question

Which of the following is/are the main agents of soil erosion?
A) Wind and Water B) Rocks C) Sand
A.A
B.A & B
C.B & C
D.A & C

Answer 1

Hint:Soil erosion is the phenomenon in which the upper layer of soil is being removed which leads to the degradation of the soil. The upper layer of soil is the most fertile one and if it is displaced the land may lose its productivity.

Complete step by step answer:

Let’s start with discussing the soil erosion for better understanding of the question. Soil erosion is the phenomenon in which the upper layer of soil is being removed which leads to the degradation of the soil. The upper layer of soil is the most fertile one and if it is displaced the land may lose its productivity. This is a natural process and can be caused by many reasons.
The reasons given to us in this question are Wind and water, Rocks and Sand.
Let’s talk about the first reason.
The first reason that is, Wind and water both cause soil erosion. When wind blows the upper layer of soil is being displaced slowly and hence causes soil erosion. As for water when water is being passed through the soil it takes away the upper layer more furiously than wind and hence causes the soil erosion.
Coming to the second and third option which are Rocks and Sand respectively they both don’t cause any soil erosion.
Hence,
$\therefore $ The answer to this question is option A.

Note:
We have to remember that soil erosion is a relatively slow process if human intervention is zero. If there is human intervention then there might be two cases one is there is even slower soil erosion and the other one is the phenomenon of soil erosion increases. The major impact is the reduced agriculture productivity.
