The highly eroded and lower form of the Aravalli Mountains indicates what?

Answer and explanation

Correct answer: Their very old age

Mountain relief provides evidence about geological history. A mountain system that has existed for a very long time is exposed repeatedly to weathering, running water, wind, and other erosional agents. These processes gradually lower peaks, widen valleys, and make slopes more rounded and irregular. The Aravalli Mountains show this worn-down and relatively low relief, so option A, their very old age, is correct. A newly formed glacial range would not normally display such prolonged erosion. The Aravallis are not identified as marine coral mountains, and a low eroded profile certainly does not prove complete snow cover. The conclusion comes from linking present landform appearance with the duration of erosion.
