2. In glaciers water becomes into ice

3. -Ice moves
downhill under
the force of
gravity.

5. River and Glacial
Erosion

6. -It is when ice freezes
and sticks to rock. When
the ice moves, large
pieces of rock are pulled
away with it.
Corries
-They are also known as
cirques or chums. They are
deep, rounded hollows with a
steep back wall and a rock
basin.

8. -In most cases, glacier is
along an existing river valley,
eroding both the floor and
the sides of the valley to
form a glacial trough.
-The characteristic V-shape
of a river valley is turned
into the typical U-shape of
a glaciated valley.

9. -They result from
differences in the rate of
erosion between glaciers in
the main and in a tributary
valley.

10. Erratics

11. -It marks the furthest or
maximum point that a glacier
reached.
