Question

Why Ninety East ridge name has been given to this north-south extending range in the eastern Indian Ocean (Bay of Bengal)?

Answer 1

• This landform is named the Ninety East ridge because it is located near the spot where the parallel of latitude strikes along the 90th Meridian at the center of the eastern hemisphere. 
• It is one of the important relief features of the Indian Ocean because it divides the Indian Ocean into the west and the east Indian Ocean.
