Question

How are deltas formed.​

Answer 1

Answer:

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

When a river reaches a lake or the sea the water slows down and loses the power to carry sediment. . The sediment is dropped at the mouth of the river. Some rivers drop so much sediment that waves and tides can't carry it all away. It builds up in layers forming a delta.
