GEOLOGY

Detailed explanation-1: -The Antarctic ice sheet is the largest single mass of ice on Earth. It covers an area of almost 14 million km2 (5.4 million mi2) and contains 30 million km3 of ice. Around 90% of the Earth’s ice mass is in Antarctica, which, if melted, would cause sea levels to rise by 58 meters (190 feet).

Detailed explanation-2: -The two ice sheets on Earth today cover most of Greenland and Antarctica. During the last ice age, ice sheets also covered much of North America and Scandinavia. Together, the Antarctic and Greenland Ice Sheets contain more than 99 percent of the freshwater ice on Earth.

Detailed explanation-3: -The Greenland and Antarctic ice sheets are the largest bodies of ice in the world and play an important role in the global climate system. Both ice sheets have been losing mass at an increasing rate since the 1990s, which has contributed one third of the global sea level rise over this period.

Detailed explanation-4: -The Antarctic Ice Sheet covers 8.3% of the Earth’s land surface. The Greenland Ice Sheet has a sea level equivalent ice volume of 7.42 m, and covers 1.2% of the global land surface (BedMachine).

Detailed explanation-5: -Greenland Ice Sheet, also called Inland Ice, the single ice sheet or glacier covering about 80 percent of the island of Greenland and the largest ice mass in the Northern Hemisphere, globally second in size to only the ice mass that covers Antarctica.
