Which of the following is the oldest mountain range in India?

Concept

A mountain range is dated from the age and tectonic history of the rocks and structures that formed it. Ancient fold ranges are usually low and rounded because prolonged weathering and erosion have worn them down over geological time.

Application

The Aravali range is a highly eroded ancient fold system extending across Rajasthan toward Haryana and Delhi. Its great age and subdued relief distinguish it from the younger or differently formed ranges listed in the question.

Contrast

• Vindhyachal is chiefly a central Indian system of sedimentary escarpments and highlands.

• The Western Ghats form the prominent western escarpment of the Deccan Plateau.

• Satpura is a central Indian highland system between the Narmada and Tapti valleys.

• Aravali is an ancient, deeply eroded fold-mountain system of north-western India.

Result

Therefore, the oldest mountain range among the offered choices is the Aravali range.
