SG3A- A case study of one landscape associated with the action of valley glacier: Lake District Flashcards
(38 cards)
Where is the lake district located?
North west england of the county of Cumbria, a little below the scottish border.
What is the key noticeable glacial period that impacted the shape of the Lake District?
The Divension Glacial peaked around 18,000 years ago,
An example of a corrie?
Red Tarn
What is the size of Red Tarn?
Height of tarn above sea level is 720m and the vertical height of the back wall is 216m.
An example of an arete?
Striding Edge
What is the length of the arete?
2km
An example of an Hanging Valley?
Glenridding Beck
What is length of the Glenridding Beck?
5km
An example of a glacial trough?

13km
An example of a ribbon lake?
Ullswater
What is the length of the ribbon lake ullswater?
11km long
An example of a roche moutonee
Norfolk Island
What is the area of the roche moutonee?
1000m squared
An example of the hummocky moraine?
Glenridding Beck
An example of end moraine?
Red Tarn
An example of a drumlin?
Eden Vale
An example of an erratic?
Allonby, North west coast of Lake District.
Why is the hummocky moraine present?
mounds of glacial till left by the retreating corrie glacier. Such tills are often left by the ice as it melts.
Why is end moraine present?
Where glacial ice of the corrie was thin, deposited occurred building up a moraine
Why is drumlins present?
Where glacier was thinning in zone of ablation, the energy levels were low and competence of the ice was low. Deposition of sub glacial till occur creating swarms of drumlins.
Why is erratics present?
Large boulder transported by glacier from Criffel and then deposited in Alloby. The boulder grande which is different to the bedrock it sits on.
What are the physical factors that influence the formation of landforms in the Lake District?
- Latitude
- Altitude
- Geology
How does latitude impact the area of Lake District?
The lake district is at a latitude of 54 degrees N. The lake district is a doomed upland area which has been pushed up by a great earth movements many millions of years ago. The location of the lake district results in colder climate due to dispersed sun’s rays.
