How does river originate from mountain? Describe briefly.

The source of a river may be a lake where lots of water from small streams gathers when it rains or snows. A river may begin in mountains where there is snow. The melting snow runs together to form a small stream that runs down the mountain.

Explanation:

Most rivers begin life as a tiny stream running down a mountain slope. They are fed by melting snow and ice, or by rainwater running off the land. The water follows cracks and folds in the land as it flows downhill. Small streams meet and join together, growing larger and larger until the flow can be called a river.Explanation:
