The last ice age and glacial ice today

Key ideas

1. The last Ice Age (Pleistocene) covered a significant time scale and ended around 10,000 years ago.
2. The  ice cover in the northern hemisphere at that time spread well into continental Europe and where is now the USA.
3. There are two main types of ice coverage

Terms

Pleistocene, valley glacier, ice sheet, snow line, erosion, deposition

Activities

Using p100 in H, investigate the following:

1. How does ice form from snow?
2. What is ice called when it moves on a large scale?
3. When did the Pleistocene Ice Age begin and end?
4. How much of the earth's surface did it cover?
5. What was the extent of it's coverage?
6. What was the coverage in the UK?
7. Describe the scene if you had been around in the Hetton area 18,000 years ago.
8. What is the 'snow line'?
9. What is the landform evidence of glacial erosion and deposition in the UK?
10. What is a valley glacier?
11. Name an example of a valley glacier and the mountain range it is located in.
12. What is an ice sheet?
13. Where do they exist now?
