Detailed explanation-1: -Glacier ice Worldwide, glaciers cover about 10% of the Earth’s land area, and Antarctica accounts for about 85% of this total cover. By volume, Antarctica contains 90% of the world’s glacier ice – enough ice to raise world sea level by almost 60 metres if it were all to melt.
Detailed explanation-2: -About three-quarters of Earth’s freshwater is stored in glaciers. Therefore, glacier ice is the second largest reservoir of water on Earth and the largest reservoir of freshwater on Earth!
Detailed explanation-3: -The amount of world’s freshwater in polar ice caps and glaciers is 70%.
Detailed explanation-4: -Ice caps and global water distribution As these charts and the data table show, the amount of water locked up in ice and snow is only about 1.7 percent of all water on Earth, but the majority of total freshwater on Earth, about 68.7 percent, is held in ice caps and glaciers.
