Explanation:

- Statement 1 says: The predominant wind direction in Rajasthan is from North-East to South-West, so the desert expands in that direction.

- This is incorrect. The prevailing wind direction is actually from South-West to North-East, not North-East to South-West. Thus, desertification tends to move eastward, not southwest.

- Statement 2 says: Thar is a monsoon-driven sand desert with wind erosion mainly in summer, and Aravalli range acts as a barrier, but mining cuts increase desert spread.

- This is correct. The Aravalli range does act as a barrier. Human activities like mining create gaps, allowing sand movement and leading to desert expansion.

- Option 1: Only statement 1 is correct.

- Option 2: Only statement 2 is correct. (Correct answer!)

- Option 3: Both 1 and 2 are correct.

- Option 4: Neither 1 nor 2 is correct.
