True.

To determine if a statement is true or false, we can use our knowledge or refer to reliable sources. In this case, the statement is true. A river delta is a landform that forms at the mouth of a river, where it slows down and deposits sediment as it flows into a body of water, such as a lake, sea, or ocean. This sediment accumulation creates a triangular or fan-shaped area of land, often characterized by smaller channels or distributaries that form as the river splits and spreads out.
