Formation of a Pyramidal Peak

Question 1

Introduction 1st mark
(Pyramidal peak is a jagged…)

Answer 1

Pyramidal peak is a jagged, pointed peak formed when 3 or more carries occur on a mountain. i.e Helvellyn

Question 2

Glacier formation 1st mark
(Snow accumulates…)

Answer 2

Snow accumulates on a north/northeast facing hollow on a mountainside.

Question 3

Glacier formation 2nd mark
(Here, more snow…)

Answer 3

Here, more snow accumulates in the winter than melts in the summer, this snow is compressed to form neve ice.

Question 4

During glaciation 1st mark
(In the corries…)

Answer 4

In the corries, the glaciers move downhill due to gravity.

Question 5

During glaciation 2nd mark
(As this happens…)

Answer 5

As this happens, plucking occurs on the back walls making the mountain top between the cores steeper and narrower.

Question 6

During glaciation 3rd mark
(Plucking is when…)

Answer 6

Plucking is when ice freezes onto bedrock pulling loose rocks away as it moves.

Question 7

During glaciation 4th mark
(Moraine from plucking and FTW..)

Answer 7

Moraine from plucking and FTW becomes embedded in the ice and grinds the curries as the glacier moves - this deepens the corries and makes the mountaintop more prominent.

Question 8

During Glaciation 5th mark
(This is…)

Answer 8

This is abrasion.
