Session 15 (Cryosphere and Global Sea Level rise)

Question 1

Glacier

Answer 1

Extended mass of ice formed from snowfall. Moves very slowly.

Question 2

Valley Glacier

Answer 2

Descending from high mountains

Question 3

Continental Glaciers

Answer 3

Centers of accumulation

Question 4

How can the ocean be responsible for its own rising?

Answer 4

When water heats up, it expands, taking up more space

Question 5

Accumulation

Answer 5

Growth in ice mass and causes potential for Ablation

Question 6

Ablation

Answer 6

Loss in ice mass and potential for

Question 7

Ice sheet feedback loop

Answer 7

Warming at surface -> higher surface melt -> lowering surface elevation

Question 8

Greenland vs Antarctica Ice sheet

Answer 8

Greenland is melting at lower parts of the surface (Air temp) while Antarctica is melting at the ice shelves (ocean temp)

Question 9

How does ocean temperature increase affect the floating ice shelf in Antarctica?

Answer 9

Warm water melts under the floating ice shelf causing it to break off

Question 10

Does the thinning of the ice shelf cause seal level rise?

Answer 10

No, but it does increase the ice flow speed to the sea, contributing to sea level rise.
