What is the strongest geological basis for considering the Himalayas young fold mountains?
Answer and explanation
Correct answer: Their formation by compression of the Indian and Eurasian plates
Option A is correct. The Himalayas formed when the northward-moving Indian Plate collided with the Eurasian Plate. Compression at this convergent boundary folded and uplifted layers of marine and continental sediments, producing a high mountain system that is still tectonically active. Ongoing uplift, earthquakes, steep slopes, and frequent landslides are consistent with the idea of a young fold mountain range. Deccan lava is related to ancient volcanism, not Himalayan folding; the Aravalli is an old eroded range, not coral; and Ganga alluvium is loose river sediment deposited in the plains. Therefore plate compression provides the strongest geological basis.
