Ice sheets are made of snow that builds up and gets compressed into ice, which then flows downhill toward the coast. What controls the mass of the Greenland and Antarctica ice sheets?

What is the coldest part of an ice sheet?
Sea ice is frozen sea water.
"Albedo" is a measure of an object's "brightness" — i.e., how much of the sunlight that hits the surface is reflected away. Which has a higher albedo?
What is the main difference between the Arctic (North Pole) and the Antarctic (South Pole)?
Since 1958, Arctic ice cover has lost how much of its thickness at the end of summer?
Ice cap melting from which land mass(es) can affect Earth's spin?
What proportion of the world's freshwater is stored in glaciers and ice caps?
Melting sea ice could raise sea level by several meters.
When sea ice in the polar regions shrinks or grows, it affects:
