• Can you name the world’s largest island?
  Over 50,000 people live there
• When you get this far north, the night sky sometimes fills with sheets of colored fire.
  Want to see?
• A massive sheet of ice covers over 1,500 miles of this chilly country.
  How thick is it?
• This Inuit island is three times the size of Texas.
  Where is it?

An iceberg is a large piece of ice from freshwater that has broken off from a snow-formed glacier or ice shelf and is floating in open water.  It may subsequently become frozen into pack ice. Alternatively, it may come to rest on the seabed in shallower water, causing ice scour (also known as ice gouging) or becoming an ice island.
