Assertion (A) : Some of the factors that are involved in soil formation are also responsible for soil erosion.
Reason (R) : Strong winds and flowing water help in soil formation through withering of rocks. The uncovered loose soil gets eroded and carried away by the winds to other places. When rain falls on the unprotected top soil, water washes it down into the streams and rivers.
In the light of the above statements, choose the most appropriate answer from the options given below :
Assertion (A) states that factors involved in soil formation are also responsible for soil erosion.
Reason (R) explains how winds and water contribute to both soil formation (through weathering) and soil erosion.
Reason (R) directly explains Assertion (A). It details how the agents that break down rocks (weathering, aiding soil formation) also carry away the resulting soil (erosion). This confirms that the factors involved in soil formation are indeed responsible for soil erosion.
Thus, both statements are correct, and Reason (R) provides the correct explanation for Assertion (A).
The most appropriate answer is that both (A) and (R) are correct, and (R) is the correct explanation of (A).
