Assertion: Soil erosion is a major problem in hilly areas.
Reasoning: The steep slopes and heavy rainfall in hilly areas make them vulnerable to soil erosion, which can lead to loss of topsoil, reduced soil fertility, and landslides.
(A) Both A and R are true and R is the correct explanation of A.
(B) Both A and R are true, but R is NOT the correct explanation of A.
(C) A is true, but R is false.
(D) A is false and R is true.
Answer:
The correct answer is (A) - Both A and R are true and R is the correct explanation of A.

Soil erosion is the removal of soil by water, wind, ice, or gravity. It is a natural process that can be accelerated by human activities such as deforestation, overgrazing, and poor land management. Hilly areas are regions with high elevation and relief , where the slope of the land is steep and the rainfall is high.
Therefore,
- Assertion (A): Soil erosion is a major problem in hilly areas - This is true, as soil erosion can cause serious damage to the environment and livelihoods of people living in hilly areas. Soil erosion can reduce the quality and quantity of soil, which affects the productivity and diversity of crops and vegetation. Soil erosion can also increase the risk of landslides, which can destroy homes, roads, and infrastructure.
- Reasoning (R): The steep slopes and heavy rainfall in hilly areas make them vulnerable to soil erosion, which can lead to loss of topsoil, reduced soil fertility, and landslides - This is also true, as the steep slopes and heavy rainfall are the main factors that influence soil erosion in hilly areas.
- The reasoning is a correct explanation of the assertion , as it shows how the physical characteristics of hilly areas make them prone to soil erosion, and how soil erosion can have negative impacts on hilly areas. The assertion and the reasoning are logically related.
Hence,
- Assertion is true.
- Reasoning is true.
- And reasoning is a correct explanation of Assertion.
So, the correct answer is (A).
