Pack Ice, Glaciers & Global Warming

Question 1

What is pack ice?

Answer 1

Pack ice, is the ice floating on the oceans near the North and South Poles

Question 2

What are glaciers ?

Answer 2

Glaciers are attached to land and formed by compressed snow. (Freshwater)

Question 3

What are icebergs?

Answer 3

Icebergs are the pieces of glaciers that fell into the ocean. (Freshwater)

Question 4

How does global warming affect pack ice/ glaciers?

Answer 4

• Pack ice to melts. Causing albedo to decrease, therefore light is kept in the atmosphere, increasing temperatures and causing climate change.
• With more melting ice, it affects the salinity and temperatures between ice and water, which leads to changes in thermohaline circulation.

Question 5

What is albedo?

Answer 5

It’s the amount of light bouncing off of ice
