The land formed by deposited soil at the mouth of a river is called a delta (named for the Greek letter, which is similarly triangular in shape).
A fan-shaped deposit at the mouth of a river is known as a delta. Deltas form when a river flows into a larger body of water, like a sea or ocean, and deposits sediment and other material it has carried downstream. Deltas are typically characterized by their flat, triangular shape.
That is called a delta. Deltas are formed when sediment carried by a river is deposited as the river slows down and enters a larger body of water, such as an ocean or lake. Deltas often have a triangular shape due to the distribution of sediment as the river enters the water body.
