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.
