Detailed explanation-1: -The Antarctic ice sheet is the largest block of ice on Earth. It covers more than 14 million square kilometers (5.4 million square miles) and contains about 30 million cubic kilometers (7.2 million cubic miles) of water. The Antarctic ice sheet is about two kilometers (1.2 miles) thick.
Detailed explanation-2: -It averages 2, 160 meters thick, making Antarctica the highest continent. This ice is 90 percent of all the world’s ice and 70 percent of all the world’s fresh water.
Detailed explanation-3: -The Antarctic Ice Sheet covers an area of almost 14 million km² and contains 30 million km³ of ice. Around 60% of the world’s total fresh water (90% of the world’s surface fresh water) is held in the ice sheet, equivalent to a 70m rise in global sea level.
Detailed explanation-4: -Ice caps around the world The vast majority, almost 90 percent, of Earth’s ice mass is in Antarctica, while the Greenland ice cap contains 10 percent of the total global ice mass.
Detailed explanation-5: -Elevation. Antarctica is the highest continent on Earth: average elevation is 8, 200ft (2500m). The elevation at the South Pole is 9, 300ft (2835m). The highest point on the icecap is in Australian Antarctic Territory at 13, 451ft (4100m), at 82° 20’S, 56° 30’E.
