Q. Consider the following statements regarding the Aravalli ranges in India:

1. They are classified as Block Mountains
2. They are considered Fold Mountains
3. They represent Residual Mountains

Which of the above statements are correct?
Answer: Only 2 and 3
Notes: The Aravalli ranges are among the oldest fold mountains in India and have been subjected to weathering and erosion, making them residual mountains as well. They are not block mountains. Therefore, only statements 2 and 3 are correct; statement 1 is incorrect. The Aravallis thus exemplify both old fold and residual mountain categories.
