Question

Largest delta in India is ___________
A. Godavari delta
B. Indus delta
C. Sunderban delta
D. Kaveri delta

Answer 1

Hint: A river delta is a type of landform. It is created by deposition of sediments. These sediments are carried along by river/rivers as the flow leaves its mouth and enters stagnant water.

Complete Answer: The Sundarban Delta is the largest delta in India. ‘Sunderban’ is the name given to the most forested region, which is fully controlled by the vast Ganga-Brahmaputra-Meghna River region which is shared by India as well as Bangladesh. Initially, it was built by the deposits of river Ganga, Brahmaputra and Meghna. However, the sediments of the present-day Sundarbans Delta are being recycled from overseas. This has been made possible by semi-diurnal waves. They are occasionally enhanced by sea levels set from coastal winds, and tropical storms that occur almost always on the Bay of Bengal. Soil deposited annually in the oceans continues to be dominated by river-borne soils. This is when they are not even directly connected to the main river system for at least hundreds of years. In the present times, much of the Sundarbans Delta is covered by a large mangrove ecosystem, which remains the largest in the world despite a significant historical decline in forest cover. This is because deforestation is on the rise.

Therefore the correct answer is “C”

Note: The Sundarban Delta acts as a natural habitat for the Royal Bengal Tiger. Apart from that it also acts as storm surge protection for many people who live outside its borders.
