Answer:

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.

Hello there! A delta is formed through the process of deposition, distribution, deposition again (the heaviest sediment always deposits first, followed by the lightest), and then rock pushing.

What happens can be explained in steps:

1. The river slows

In the first step of delta formation, the river slows and water begins to deposit.

2. Distribution

In the second step, land, in a way, splits into smaller portions that the water travels through.

3. Deposition (again)

In the third step, water meets land and the heavier material begins to deposit under the lightest.

4. Formation

In the fourth step, layers of rock build up and form a delta.

Hope this helps!
