how is a delta formed?

• rivers carry sediment, that sediment is deposited at the mouth of the river into a larger body of water forming a delta

• rivers carry water and dump it into the ocean creating other pathways for the ocean water to get into

• lakes carry sediment which breaks down the rock. Then ice comes in and breaks apart the rock.

• lakes carry water that dump into rivers and then creates sediment. The sediment beaks down rocks and then they return back to the lake.
