How did the himalayas affect ancient india.

The Himalayas have a profound effect on the climate of the Indian subcontinent and the Tibetan Plateau. They prevent frigid, dry winds from blowing sound into the subcontinent, which keeps South Asia much warmer than corresponding temperature regions in other countries.
