WHERE DOES A RIVER BEGIN???
Every river has a 'source', a place
where the river begins its journey.
Where is the source of a
river?
The source of a river is usually found in high
places such as hills or mountains. A river can have more than one source.
Different types of
sources
Springs
Some rivers begin where a natural spring
releases water from underground.

Rainfall and melting snow
Some rivers begin in mountains or hills, where
rain water or snowmelt collects and forms small channels, . At first, the
channels are small and are called rills. As more water enters the
channels they grow forming gullies (larger channels). The
streams in the gullies eventually become big enough to form a river.
Lakes
The source of some rivers is a lake. The
source of the River Nile is Lake Victoria, in Burundi.
Bogs
In some places, rain water can't sink into the
ground as the ground is too wet already. The water forms a bog. The water flows
out of the bog to form lakes and streams.
