The Quiz: About 80% of Greenland is covered in ice. How thick is the ice sheet?
A About 500 feet
B About 1,000 feet
C About 5,000 feet
Nearly 1,800 miles long from north to south with a maximum width of 680 miles, the Greenland ice sheet is almost a mile deep on average. And we regret to say that, unfortunately, it’s getting shallower.
The correct answer to this quiz is About 5,000 feet.
