Which statement is correct in comparing the age of the Himalayas and Aravalli?
Answer and explanation
Correct answer: Himalayas are young and Aravalli is ancient
The governing concept is the geological age and origin of Indian mountain systems. The Himalayas are young fold mountains formed by the continuing convergence of the Indian and Eurasian tectonic plates, so they are geologically young and still tectonically active. The Aravalli Range is one of the oldest fold mountain systems of the Indian subcontinent and has been greatly worn down by erosion. Therefore option C is correct. Option A reverses the comparison, while B incorrectly assigns a coral origin to both ranges. Option D confuses these mountain systems with the basaltic lava formations of the Deccan Trap.
