What effect does the very old age of the Aravalli show on its physical form?
Answer and explanation
Correct answer: It is highly eroded and relatively lower
Option C is correct because the Aravalli Range is one of the oldest fold mountain systems of the Indian subcontinent. Over a very long period, weathering, erosion, and denudation wore down its rocks and reduced the height and sharpness of its relief. Consequently, many parts appear as rounded, discontinuous, and comparatively low hills rather than young, jagged mountains. It is not permanently snow-covered, it is not submerged beneath the sea, and it is not a newly formed lava range of the Deccan. The physical appearance of an old range is therefore explained by prolonged erosion.
