Smaller streams and rivers feed into the bigger rivers. Their water usually comes from rain and lakes and water running off mountains. Large quantities of rain create floods and some of this water makes its way into the rivers.
A stream will form where there is sufficient water to flow freely, and where the slope of the land is sufficient. On a sloping plane surface, even a minor defect in the surface will allow a stream bed to form. (given a water supply).
This defect from the planar could be caused by a minor landscape fold. It could also be caused by a rockfall which left a scar on the surface. In any event, a stream when formed will stick to that first channel form until erosion; or some other major force; causes it to alter.
In my region, (central Otago) land-building processes are active, and several streams now flow in a direction opposite to their original form. This has been caused by the current phase of mountain building. These processes have isolated some fish species - notably a small fish known as Galaxid gollumoides (after Gollum of Lord of the Rings). Some snail variants have also been isolated on opposite sides of mountain streams by these local forces.
When a stream flows, it may interact with another stream causing the streams to combine and become a large river.
A large stream of surface water is usually called a river. A river is freshwater and runs from high to low ground.
Most sediment washes or falls into a river as a result of mass movement and runoff. Other sediment erodes from the bottom or sides of the river. Wind can also drop sediment into the water. Hope I helped! -DorkyGeek77
a river is colder then a stream b/c one of them is hit with sunlite
A distributary is a stream that branches off and flows away from a main stream channel while a tributary is a stream or river which flows into a mainstem river.
The small streams are tributaries to the river.
A stream or brook can get bigger and become a river.
A tributary.
A large natural stream, which may be a waterway.
River, stream, waterway, brook, canal, or watercourse
A river??
A large stream of water that flows across the land is known as a river. There are more than 250,000 rivers located in the United States alone.
A tributary
Small river.
the large body of water that flows across the land is a river.
A Tributary
River, stream, waterway, brook, canal, or watercourse
That would be a river.
