Question

How is the Sundarban delta formed?

Answer 1

Hint:
I) The Sundarban forest lies in the vast delta on the Bay of Bengal.
II) Deltas are wetlands that form into another body of water, such as an ocean, lake, or another river, as rivers empty their water and sediment.
III) While very rare, deltas may often empty into land. As it reaches its mouth, or end, a river flows more slowly.

Complete answer:
In the vast delta on the Bay of Bengal created by the super confluence of the rivers Ganges, Padma, Brahmaputra and Meghna throughout southern Bangladesh, the Sundarban forest lies. From the mangrove forests on the coastal edge, the seasonally flooded Sundarbans freshwater swamp forests lie inland.
The Bhagirathi-Hooghly (a distributary) flows southward through the deltaic plains to the Bay of Bengal as the Ganga flows to West Bengal, split into two. The main stream flows into Bangladesh southwards and is joined by the Brahmaputra, resulting in the delta formation.
The name Sundarbans is thought to be derived from the name of the large mangrove trees that are most abundant in the region, sundri or sundari (Heritiera fomes).
The Sundarbans, known for its rare mangrove forests, is a cluster of low-lying islands in the Bay of Bengal, spread throughout India and Bangladesh. This active delta area, measuring approximately 40,000 sq km, is among the world's largest.

Note: The Sunderban delta is formed by the convergence of the Ganga, Padma, Brahmaputra and Meghna rivers. It gets its name from the mangrove trees, which are found there more than anywhere else in the world. This active delta region is among the world's highest, measuring approximately 40,000 sq km.
