A river is a stream of water that flows through a channel on the surface of the ground. The passage where the river flows is called the riverbed and the earth on each side is called a riverbank. A river begins on high ground or in hills or mountains and flows down from the high ground to the lower ground, because of gravity. A river begins as a small stream and gets bigger the farther it flows.
