runoff can pollute a river or stream because when the water flows over the ground, it could pick up some trash or garbage on the ground, and the garbage could flow with the runoff. Then when the runoff enters a stream, lake, or ocean, the garbage will flow into the water, causing pollution.
Usually, the river ends up being polluted with whatever that runoff was carrying.
The water level in the river will rise depending on the ammount of runnoff.
A water cycle :]
brook, stream, runoff The delta
First the water will rain down, causing runoff, and the runoff water will carry dirt and sediment with it, causing a stream to form overtime as the runoff trail keeps on indenting into the ground.
A channel through which water is continually flowing downhill is a stream. A large channel in soil that carries runoff after a rainstorm is a gully.
....runoff is when water overflows from a river so if theres too much rain it could overflow the river and create a runoff
It could cause fatal disease if not handled carefully!
It could be called runoff, feeder stream or source.
That's easy. It gets into the water table and pollutes it, or it can get there by runoff.
It will just accumulate more water in the river but, if the runoff water becomes toxic due to nearby factories or power plants then it can damage that ecosystem.
throwing garbage in the river.....
Runoff is extra water that came from anoter body of water, usually after a big rainstorm. If there is enough water going down hill, it can form a river.
