how are Delta's formed?
answer in 2 lines.​

Answer 1

Explanation:

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.

Answer 2

A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water.
