How does a river start?
How are rivers formed? Rivers usually begin in upland areas, when rain falls on high ground and begins to flow downhill. As rivers flow, they erode – or wear away – the land. Over a long period of time rivers create valleys, or gorges and canyons if the river is strong enough to erode rock.
How do rivers originate from mountains?
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. As more little streams run in, the main stream gets bigger, until it forms a river. Some rivers only flow after there has been rain near the head water.
Where do rivers start and finish?
A river begins at a source (or more often several sources) which is usually a watershed, drains all the streams in its drainage basin, follows a path called a rivercourse (or just course) and ends at either at a mouth or mouths which could be a confluence, river delta, etc.
What are the 3 stages of a river?
3 Stages of a River
- YOUTHFUL STAGE (UPPER COURSE) – V- Shaped Valley > Erosion.
- MATURE STAGE (MIDDLE COURSE) – Meanders > Erosion and Deposition.
- OLD AGE STAGE (LOWER COURSE) – Floodplains > Deposition.

How are rivers formed answer?
river forms from water moving from a higher elevation to a lower elevation, all due to gravity. When rain falls on the land, it either seeps into the ground or becomes runoff, which flows downhill into rivers and lakes, on its journey towards the seas.
How are rivers born?
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. Small streams meet and join together, growing larger and larger until the flow can be called a river.

How do you make a river?
Design your river system: add twists and turns, wide sections and narrow stretches. Deeper stretches will slow the water down, shallow spots will speed it up. Add a few rocks (“boulders”) in the narrow sections to create “rapids.” Make side pools and tributaries. Make forks in the river to split it in two.
