Question

The vulnerability of the soil to erosion is called:

• A. Erosivity
• B. Erodibility
• C. Vulnerability
• D. Erosion

Hint:

Erosivity is the power of rainfall or wind, while erodibility is the susceptibility of soil to erosion.

Answer 1

The Correct Option is B

Concept:
Soil erosion depends on both the power of the erosive agent and the susceptibility of soil to be detached and transported.

Step 1: Understand erosivity.
Erosivity refers to the ability of rainfall or wind to cause erosion. \[ \text{Erosivity}=\text{erosive power of rainfall or wind} \]

Step 2: Understand erodibility.
Erodibility refers to the vulnerability or susceptibility of soil to erosion. \[ \text{Erodibility}=\text{soil's susceptibility to erosion} \]

Step 3: Apply the definition.
The question asks about the vulnerability of soil to erosion. Therefore, it is called: \[ \text{Erodibility} \] \[ \therefore \text{Correct Answer is (B)} \]
