Rivers usually begin as a trickle of water high in hills or mountains. Some come from rainwater or melting snow. Most emerge from underground streams, formed after rain or snow seeps into the ground then bubbles back to the surface. As the water flows downhill, the trickle swells into a stream and then, as side streams called tributaries join it, into a wider river.
