WebThe ice sheet has covered large parts of Greenland for the last 2-3 million years, but active glaciers and constant melting have meant that the ice has been recycled many times. … WebThe Greenland Ice Sheet is a frozen reservoir for 8 percent of all freshwater on the planet. Glaciers, such as the Petermann Glacier along the island’s northern margin, drain the interior, returning this water to the sea as icebergs. Melt water can accelerate the flow of a glacier by lubricating the underside as it scrapes over the rocky terrain.
