Question

Describe the location, extent and formation of the Ganga-Brahmaputra delta in India and Bangladesh.

Answer 1

Hint: 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 into it. Deltas may also empty into the land, but are very rare. As it reaches its mouth or end, a river flows more slowly. This allows sediment, dense material carried by currents downstream, to sink to the bottom of the river.

Complete solution:
Location: The Ganga-Brahmaputra Delta is located in Asia where the Ganges and Brahmaputra rivers discharge into the Bay of Bengal. The delta is also called the Ganges Delta, Sundarban Delta, or Bengal Delta.

Extent: With a surface area of some 100,000 km, it is the largest Delta in the world. About two-thirds of the delta is situated in Bangladesh, while the remainder is in West Bengal, India. The floodplain of three great rivers is the Ganges Delta: the Ganges, the Brahmaputra, and the Meghna. These three rivers together drain a catchment of around 1,72 million square kilometres on the southern side of the Himalayas.

Formation: Through the three major river systems: the Ganges, Brahmaputra, and Meghna, it drains almost all of the Himalayas, the most sediment-producing mountains in the world. These systems bear the largest sediment load in the world, with more than 1 billion tonnes of sediment per year, almost 80% of which is delivered during the four monsoon months. The delta is formed by the deposition of sediments by Ganga and Brahmaputra. A tide-dominated delta in the Bengal Delta, where tides play a key role in the process of sediment dispersal and delta shaping. The river is called the Padma, downstream from the confluence. The Meghna enters the Padma about halfway.

Note:
Deltas are extremely important to a region's economy. For example, they are significant places for trade and commerce. The Ganges-Brahmaputra delta is almost entirely occupied by Bangladesh. The delta's leading agricultural products are tuna, other seafood, and crops like rice and tea.
