A geographical feature typically found at the end of a river is a delta. Deltas are landforms created by sediment deposition as the river slows and meets a larger body of water, such as an ocean or lake. The accumulation of sediments over time leads to the formation of rich and fertile land, often home to diverse ecosystems and a variety of plant and animal species. Deltas are vital for agriculture and serve as important habitats for wildlife, supporting both commercial fishing industries and local communities dependent on natural resources.
