Rivers

how are rivers formed?

A river is a large stream of freshwater. The beginning of a river is called the head.

It takes many tributaries to form a river.

 

Rivers begin at their source in higher ground such as

mountains and hills, where rain water or melting snow collects and forms tiny streams called tributaries.

A river grows larger as it collects water from more

tributaries along it's course.

Most rivers flow into a larger area of water such as a

sea or lake. The end of the river is called it's mouth.
