Question

Given below are two statements: Assertion (A): The amount of soil erosion depends upon a combination of the power of rain or wind to cause erosion and the ability of the soil to withstand the impact. Reason (R): The soil and water conservation falls into two categories, viz. agronomic measures and mechanical protection measures.

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is not the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Soil erosion depends on erosivity of the agent and erodibility of the soil.

Answer 1

The Correct Option is B

Concept:
Soil erosion depends on erosivity and erodibility.

Step 1: Check Assertion.
Rain or wind provides erosive force. Soil resistance decides how easily soil particles are detached. \[ A \text{ is correct} \]

Step 2: Check Reason.
Soil and water conservation measures are broadly grouped into agronomic and mechanical measures. \[ R \text{ is correct} \]

Step 3: Check explanation.
Reason classifies conservation measures, but it does not explain the amount of soil erosion. \[ R \text{ is not the correct explanation of } A \] \[ \therefore \text{Correct Answer is (B)} \]
