Cool Glacier Facts

Glaciers cover 15 million square kilometers of the Earth’s land surface.

About three-quarters of Earth’s freshwater is in glaciers.

The world’s largest glacier today is the ice sheet that covers East Antarctica, which in places is over 4200 meters thick.

The world’s longest glacier today, the Bering Glacier in Alaska (US), is 204 kilometers long.
