Question

how does a river form delta?

Answer 1

Answer:

Formation of Delta

Formation of DeltaA river moves more slowly as it nears its mouth, or end. This causes sediment, solid material carried downstream by currents, to fall to the river bottom. The slowing velocity of the river and the build-up of sediment allows the river to break from its single channel as it nears its mouth.

Answer 2

Deltas are wetlands that form as rivers empty their water and sediment into another body of water, such as an ocean, lake, or another river. Although very uncommon, deltas can also empty into land. A river moves more slowly as it nears its mouth, or end.
