- The Cryosphere refers to places on Earth that have water year round as snow and ice.
- A glacier can contain ice, water, rocks, snow, and other materials.
- A huge mass of ice covering millions of acres of land is called an ice sheet.
- Antarctica's ice sheet is three miles thick.
- Ice shelves are thick sheets of ice.
- Icebergs are giant, floating pieces of ice that have broken away from an ice shelf.
- When an iceberg is blue, that means it is older and denser.
- Icebergs can change in size.
- Hail forms when snow rises and falls in a cloud, water sticks to it, and then freezes.
- During the ice age, nearly 1/3 of the Earth was covered in ice.
- 9/10 of an iceberg is underwater.
