A delta is a landform created at the mouth of a river where it flows into a larger body of water, such as an ocean or a sea. Deltas are important for flood control, sediment trapping, and as centers of agricultural activity.
Deltas form when sediment carried by the river is deposited at its mouth, creating a triangular or fan-shaped area of land. These fertile areas are characterized by a network of distributaries, marshes, and wetlands, providing habitats for diverse flora and fauna.
