UNIT  7   RIVERS

A river is a body of moving water. It has three stages in its life:

• a river starts high in the mountains
• then, the river flows over the surface
• and finally the river ends into a sea, lake or another river

We can also distinguish three parts:

• source: the beginning
• course: the route
• flow: amount of water
• mouth: the end

A river basin is an área of low land drained by a river and its tributaries.

Tributary = affluent: river or stream that flows into a main river o a lake (not sea or ocean).

Watershed: area where all the rivers flow into the same sea.

Here you have a diagram showing these concepts:
