Land Ice

Unlike sea ice, ice sheets are formed on top of land in Antarctica and Greenland. The Greenland Ice Sheet holds roughly 7% of the world’s freshwater. Glaciers from this ice sheet move from the interior of the island toward North America and eventually break off into icebergs and melt in the Atlantic Ocean. Recent warming has caused an increase in the ‘flow’ of this glacial movement.
