Learn the basics about rivers

5. Meanders are where the
river bends.
Meanders normally occur
in the middle and lower
courses where the water
is moving more slowly.

6. The mouth of a river is
where the river flows into
the sea , a lake or a
larger flow of water.
This is where the river
ends.

7. Tributaries are streams
or small rivers that flow
into a bigger river.

8. The source of a river is
where the river starts
The source of a river may
be a lake,
a spring,
snow capped mountains,
or a glacier.

9. Deltas are little islands
formed at the mouth of
the river.
Deltas form because when
the river enters the sea
the current weakens and
it drops gravel, mud and
sand.

10. Erosion is where over
time the river removes
rock from the river banks
or bed.
This can happen by the
river breaking down the
rocks,
Or the river removing the
material of the river
banks

11. Flood plains are flat
areas around a river that
occasionally floods.
These are formed
because the river floods,
deposits sand, gravel
or/and clay, that over
time compress together
to make a waterproof
surface.
So when it rains it floods
easily.

12. A canyon is a long deep
narrow valley with steep
cliff walls that normally
has a river at the bottom.
Canyons are formed by
running water cutting
through a dry area.
