Question

What is a delta? Name the biggest delta in the world.

Answer 1

Delta is a triangular landform that a river forms near its mouth (where it meets the ocean or sea). Since the river deposits most of its sediments near the mouth, these deposited sediments force the river to split into several distributaries and this region is collectively known as Delta.

The Ganga-Brahmaputra Delta is the biggest delta in the world.
