What is a river?

A river is a large, flowing body of water that typically flows towards an ocean, sea, lake, or another river. Rivers are formed by the accumulation of water from precipitation, melting snow, or underground springs. They play a crucial role in the Earth's water cycle and are important for providing habitats for various plants and animals, as well as serving as a source of water for human activities such as agriculture, industry, and transportation.

A river is a natural watercourse, usually freshwater, flowing towards an ocean, sea, lake, or another river. In some cases, a river flows into the ground and becomes a subterranean river. Rivers are part of the hydrological cycle, the continuous movement of water on, above, and below the surface of the Earth.
