WORLD HISTORY

Detailed explanation-1: -When large amounts of alluvium are deposited at the mouth of a river, a delta is formed. The river slows down at the mouth, so it doesn’t have the energy to carry all the silt, sand, and clay anymore. These sediments form the flat, usually triangle-shaped land of a delta.

Detailed explanation-2: -Deltas are areas near the mouth of a river or estuary, where these moving bodies of water deposit large amounts of sediment.

Detailed explanation-3: -A delta is a landform created by the deposition of sediments that is carried by a river as the flow leaves its mouth and enters slow-moving or stagnant water. This is usually formed when the river meets the ocean.

Detailed explanation-4: -A delta is a fertile landmass formed by accumulation of alluvial deposits at the mouth of a river (the place where a river enters the sea). The rivers Ganga and Brahmaputra form the worlds largest delta, the Sunderbans delta, which is triangular in shape. Suggest Corrections.
