Corries

Question 1

First stage in the formation of corries

Answer 1

Snow builds up in a hollow high
up on the north face of
mountain sides. A year later a
small glacier forms.

Question 2

Second stage in the formation of corries

Answer 2

The ice moves under its own
weight in a circular way called
rotational movemen

Question 3

Third stage in the formation of corries

Answer 3

A small corrie full with ice,
flows out onto the main valley
glacier

Question 4

Fourth stage in the formation of corries

Answer 4

The mountain top is weathered
by freeze-thaw. Persistent
freezing and melting breaks
sediment off which falls into
the ice

Question 5

Fith stage in formation of corries

Answer 5

Erosion on the back wall is
caused by plucking. Water
freezes and pulls off rock. It
develops a vertical shaped,
jagged appearance

Question 6

Sixth stage of the formations of corries

Answer 6

Rocks that have fallen into the
glacier ice scrape away the
floor by abrasion. A deep bowl
shape is formed

Question 7

Seventh stage in a formation of a corrie

Answer 7

There is less erosion at the
front of the corrie as the ice is
thinner so a lip or rock bar
forms. Also moraines are
deposited here

Question 8

Last stage in the formation of corries

Answer 8

When the ice melts a small, but
very deep lake often forms in
the hollow called a tarn
