Question

Explain the role played by the peninsular India and the Himalayas in the formation of the Indo-Gangetic Plain.

Answer 1

• The Himalayas provided sediments through erosion of mountains. Rivers like the Ganga, Yamuna, and Brahmaputra carried these sediments into the depression.
• The Peninsular India acted as a rigid and stable block. When the Himalayas rose, the area between the Himalayas and Peninsular India sank to form a trough or depression.
• This depression was filled with alluvial deposits from rivers originating in the Himalayas, creating the Indo-Gangetic Plain.

So, the Himalayas provided material, and the Peninsular India supported the formation of the plain.
