Glacier and corrie formation ap

1. How do Glaciers Form and how do they shape the land?

2. Read through the cards and try to work out what happened to Stardust – you could even try to organise the cards into chronological order. WHY did the aircraft disappear and then re-appear over 50 years later? The Stardust Mystery

3. How do Glaciers Form? Discuss this with the person next to you Watch this video to find out more

4. What is a Glacier? Put the boxes in the correct order! R. All the weight of the ice pushes the glacier down the mountain C.The new layers of snow compact last years layer A. It snows again next winter L. The spring and summer are cold so the snow doesn’t melt G. Snow collects throughout the winter I. Air is therefore squeezed out if the snow – turning it to ice. E. With no air the glacier turns a strange blue colour

6. RECAP: What processes shape the land in mountain areas?

7. Freeze Thaw Weathering On your worksheet – complete the following notes…. Freeze thaw weathering

8. Debris from freeze thaw weathering People – for scale!

9. Erosion is the break down and wearing away of rocks involving movement. Ice erodes by 2 main processes – plucking and abrasion . Glacial Erosion

10. 1) Plucking Plucking is when rocks and stones become frozen to the base of the glacier and are plucked from the ground as the glacier moves down the valley.

11. 2) Abrasion Abrasion occurs when rocks and stones, picked up by the glacier, through plucking at the bottom of the glacier, are rubbed along the bottom of the valley, digging it out.

12. Abrasion that has been carried out over rocks in Iceland – smoothing the rocks

13. Glacial Landforms / Features – What landforms do you see?

15. Corrie – contour pattern tarn contours close together

16. Annotate your outlines to explain how a corrie is formed. Make sure you have used specific terminology: Freeze-thaw weathering Plucking Abrasion Steep back wall Corrie lip Tarn Corrie lake called a tarn Debris ridge called a corrie lip Freeze-thaw weathering Freeze-thaw weathering The Formation of a Corrie

17. Cartoon time Create a cartoon from the point of view of a snow flake which joins other snow flakes to form a glacier. Describe your adventures and how strong you have become…so much so that you have managed to carve different landforms out of solid rock- such as corries! It could be a cartoon strip if you like!

18. Hey, you lot up in those clouds! Fall down with me. Ouch! You’re squashing me! This is cool – we are turning into blue ice

19. Homework Complete your cartoons
