The Bay of Bengal is surmounted by the Ganges Cone, an enormous deposit of sediment forming an extensive continental rise that extends hundreds of miles into the Bay. This sediment was deposited by the Ganges-Brahmaputra river system, one of the world’s great rivers. This system, carrying a greater quantity of sediment than any of the other great rivers, has formed an immense delta as well as the cone.

The Indus River, on the eastern side of the Indian subcontinent, also carries a tremendous amount of sediment. Does it form a similar cone? Why?
