Question 5

During glaciation 7th mark

Question 6

During glaciation 5th & 6th mark
(Abrasion occurs…)

Answer 6

Abrasion occurs, deepening the valley. (5th) Abrasion is when moraine from plucking and FTW is embedded in the ice and grinds the base of the valley floor.

Question 7

During glaciation 3 & 4th mark

Answer 7

Plucking occurs on the sides of the valley making it steeper (3rd) Plucking is when ice freezes onto bedrock, pulling loose rocks away as it moves (4th)

Question 8

During glaciation 1st & 2nd mark
(Corrie glacier…)

Answer 8

Corrie glacier flows downhill due to gravity(1st), into a U shaped valley(2nd)

Question 9

After glaciation 1st mark
(A waterfall…)

Answer 9

A waterfall may flow down hanging valley to reach the main valley floor.
