The Story Of Rivers

           


Rivers are vital carriers of water and nutrients to areas all around the earth.The world is blessed with hundreds of thousands of rivers which apart from their beauty play a vital role in nature.They are of great importance geographically,biologically,historically and culturally.

There are rivers in every continent except Antarctica.Rivers are an important part of the earth's topography as they carry huge quantities of water to the sea from the land."

In simple words a river is fresh water flowing across the surface of the land usually to the sea.It flows in a channel of which the bottom is called the bed and the sides of the channel are called the banks.

The rivers flow downstream starting from the highest point of an area and gain more water from other streams, rivers, Springs, added rainfall and other water sources.


Rivers bogin in mountains or hills where rain water or snow collects and from tiny streams called gullies.These gullies either grow larger when they collect more water and become streams themselves or meet stream and to the water already in the stream.
 


Most of the rivers end when they flow into a large body of water and the end of the water is called the mouth.                                                


There is usually a river delta at the mouth.It is a large,silty area where the river splits into many different slow-flowing channels with muddy banks.At the source of a river the water is usually pure.


As the water blows downstream it picks up silts and mineral salts from the soil and rock.Many other chemicals enter the river water as it flows downstream.
