Galciation

Question 1

How can people Leaving gates open be solved

Answer 1

Installing self closing gates to avoid risk of animals escaping

Install styles that tourists can climb over to avoid walls being damaged

Question 2

Pets of lead / sheep scaring

Answer 2

Putting signs to remind tourists to keep dogs on a lead and putting fines in place if they dont

Question 3

Littering

Answer 3

The Lake District had no bins to encourage tourists to take their litter home

Question 4

Foot path erosion

Answer 4

The national park educates tourists by providing information and guided walks

Using hard wearing gravel to repair damaged paths or creating new routes can make them more durable

Question 5

What is plucking ?

Answer 5

Plucking is when I’ve sticks on to rocks and as the glacier moves down hill the rock is ripped out

Question 6

What is abrasion?

Answer 6

Abrasion happens when rocks frozen into the sides or base of the glacier grind at the valley floor as the glacier moves

Question 7

What is frost shattering

Answer 7

Water collects in cracks in rocks at cold temperatures the water expands and freezes and puts pressure on the rock . This happens lots until the rock shatters

Question 8

Formation of corries

Before glaciation

Answer 8

Draw diagram*

Snow collects in hollow, air is squeezed out , turns to ice

Snow collects in north facing hollows , overtime the snow is compressed and turns to ice . I’ve moved down hill by the weight of the snow and gravity

Question 9

Formation of a Corrie

During glaciation

Answer 9

Draw diagram*

Plucking steepens Blackwall
Abrasion deepens hollow

Plucking occurs when ice sticks on to rocks and as the glacier moves the rock is ripped out.

Abrasion occurs when rocks freeze into the glacier and grinds at the hollow floor as it moves.

Frost shattering may inccorporate material into the glacier

Question 10

Formation of a Corrie
After glaciation

Answer 10

Draw diagram*
Steep back wall due to frost shattering * Corrie lip* scree* tarn*

The glacier has melted leaving an arm chair shaped hollow , with steep back walls . Water sometimes collects in a hollow and forms a tarn

Question 11

How are corries shown on an os map

Answer 11

Contour lines in a horseshoe shape
Often has a circular lake in middle may be labelled as “Corrie or “cwm”

Question 12

How are ushaped valleys shown on an os map

Answer 12

Very steep sides
often a misfit steam at bottom flat valley floor

Question 13

How are arêtes shown on an is map

Answer 13

2 corries back to back
Close contour lines
Top often has dotted lines along top(footpath)

Question 14

How is a truncated spur shown on an os map

Answer 14

Always on the sides of a u shaped valley
Can have exposed rock/scree

Question 15

Pyrimadal peaks formation

Before glaciation

Answer 15

Drawing*
Snow collects in 3 or more hollows and turns to ice
I’ve behind to move downhill, pushed by weight of snow and pulled by gravity

Question 16

Pyramidal peak formation
During glaciation

Answer 16

Drawing *

The back walls of all the corries are eroded backwards toward each other by plucking and abrasion

Plucking occurs ….
Abrasion occurs ….

Question 17

Pyramidal peak formation
After glaciation

Answer 17

The erosional processes make corries on all sides of the mountain and as glaciers erode towards each other, the corries get bigger dormoing arêtes and meat at a peak
Frost shattering erodes the top of the mountain and creates a jagged peak

Question 18

What is the case study for coasts

Answer 18

Dorset
