1.Describe the maximum extent of ice in the UK during the last ice age.
Ice covered most of Scotland, Ireland and Wales and came as far south as the Bristol channel in England
1 of 33
2.Describe two ways that ice erodes the landscape.
Plucking-where meltwater freezes onto the rock and as the glacier moves forward it pulls pieces of rock out. Abrasion-where bits of rock stuck in the ice grind against the rock below the glacier wearing it away.
2 of 33
3.What is rotational slip?
Where the ice at the top of the glacier moves in a circular motion
3 of 33
4.Explain what freeze-thaw weathering is.
Where water gets into cracks in rocks. The water freezes and expands putting pressure on the rock. The ice then thaws, releasing the pressure on the rock. If this process is repeated it can make bits of rock fall off.

5.What is a corrie?
Corries begin as hollows containing a small glacier. As the ice moves by rotational slip, it erodes the hollow into a steep-sided armchair shape with a lip at the bottom end, this is known a corrie.

6.How does a pyramidal peak form?
It's formed when three or more back-to-back glaciers erode a mountain
6 of 33
7.Give an example of a pyramidal peak.
Snowdon, Wales
7 of 33
8.Explain how a hanging valley forms.
Formed by smaller glaciers that flow into the main glacier
8 of 33
9.What is a glacial trough?
Steep-sided valleys with flat bottoms
9 of 33
10.What is bulldozing?
Where ice pushes lose material in front of it
10 of 33
11.Describe the formation of outwash.
The streams sort the material by side and deposit it in layers in front of the glacier
11 of 33
12.Give one difference between lateral and ground moraine.
Lateral moraine is a long mound of material deposited where the side of the glacier was. Medial moraine is a long ridge of material deposited along the centre of the valley floor.
12 of 33
13.Where is medial moraine deposited?
Along the centre of the valley floor
13 of 33
14.Describe the formation of terminal moraine.
Terminal moraine builds up at the snout of the glacier and material is deposited as semicircular mounds as the ice retreats
14 of 33
15.Describe what a drumlin looks like.
Elongated hills of glacial deposits. They're round, blunt and steep at the upstream end, and tapered, pointed and gently sloping at the downstream end.
15 of 33
16.What is an erratic?
A rock that has been picked up by a glacier, carried along and dropped in an area that has a completely different rock type.
16 of 33
17.How would you identify a pyramidal peak on a map?
Tightly packed contour lines that curve away from a central high point
17 of 33
18.How would you identify an arete on a map?
Really thin hill with tightly packed, parallel contours on either side
18 of 33
19.Describe what a glacial trough looks like on a map.
No contour lines on the bottom of the valley but they're tightly packed on the sides
19 of 33
20.Give an example of a glacial trough.
Nant Ffrancon

21.What does a ribbon lake look like on a map?
Flat valley with steep sides surrounding a long straight lake
21 of 33
22a.Give an example of a glaciated upland area in the UK.
Snowdonia, Glyders
22 of 33
22b.Name some of its major features of erosion.
Corries, ribbon lake, u-shaped valley
23 of 33
23.Describe what an arete looks like on a map.
Often have carries or tarns on either side and footpaths on them
24 of 33
24.Decribe the types of farming that commonly take place in glacial landscapes.
Sheep-common in upland glaciated areas because the steep slopes and poor soils make it unsuitable for most other types of farming. Cattle-kept on flatter valley floors. Crops-grass is grown to make hay and feed the animals.
25 of 33
25.Name three economic activities, other than farming, that take place in glacial landscapes.
Quarrying, forestry, tourism
26 of 33
26.Give two examples of conflicts that might be caused by quarrying in glacial landscapes.
Conservationists object to the destruction of habitats and the damage of local wildlife. Makes the environment less attractive to tourists, so they may be discouraged from visiting.
27 of 33
27.Describe the conflicts caused by a type of land use other than quarrying in glacial landscapes.
Farming-removes vegetation from landscape,tourists may block footpaths. Tourism-can damage stone walls, scare sheep, leave gates open, trample on crops. Forestry-scare off wildlife, damage habitats, makes area look less attractive.
28 of 33
28.Describe the economic impacts of tourism on glaciated upland areas.
Tourism offers employment to local people, extremely high house prices, price of goods and services are often higher.
29 of 33
29.Give two strategies that might be used to manage the social impacts of tourism.
Improve the road network to prevent traffic congestion in tourist season, resurface footpaths with hard-wearing materials.
30 of 33
30.Explain why tourists are attracted to one glacial area you have studied.
Beautiful scenery, cultural attractions and activities e.g. rock climbing
31 of 33
31.Using a named example, describe the social impacts of tourism on a glaciated area.
Traffic is heavy-89%of visitors arrive by car, prices of everyday goods are high
32 of 33
32.For a named upland area, describe one way that environmental impacts of tourism have been managed.
Coping with the noise, erosion and pollution from water sports-zoning schemes means water sports are only allowed in certain areas and there are speed limits to reduce pollution and noise.
