Among them, the Antarctic glacier is the largest glacier on the earth, accounting for 98% of the entire Antarctic continent. Antarctic ice sheet?

Other brief introduction of the three major glaciers in the world

The average thickness of Antarctic glaciers is 2000? 2500 meters, the maximum thickness is over 4000 meters. The total volume of the ice sheet is about 24.5 million cubic kilometers, accounting for 90% of the world's land ice and 70% of the total fresh water.

Greenland glacier is the second largest glacier in the world. Greenland is covered with 6.5438+0.7 million square kilometers of ice sheet, almost equivalent to the territory of Mexico, and the ice shell is 3 kilometers thick. Once it melts, the global sea level will rise by 7 meters.

Vatna Glacier is near the town of Hofen in the southeast of Iceland, covering an area of 8,300 square kilometers. It is the largest glacier not only in Iceland, but also in Europe, ranking third in the world.
