A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake, or another river. Rivers play a crucial role in the ecosystem and are sources of water for drinking, irrigation, and other human needs. They also provide habitats for various species of plants and animals and are important for transportation and commerce.

Rivers can be found on every continent and come in a variety of sizes, from small streams to large, powerful rivers like the Amazon and the Nile. The formation of a river begins with precipitation falling on high ground, which collects into streams and tributaries that eventually converge to form the main river channel. The flow of a river is determined by factors such as precipitation, topography, and geology.
