Ice
It is difficult to grasp such a scale through numbers alone, so visualizations like this help us appreciate the true dimensions of this massive ice sheet. The Antarctic ice sheet is the largest reservoir of fresh water on Earth. It covers almost the entire continent, and the ice within it has accumulated over millions of years: snow gradually compacted under its own weight and turned into dense ice.
This ice lies on land, on the Antarctic continent itself, although under enormous pressure it slowly flows from the center of the continent toward the coast, where it forms ice shelves and icebergs.
The average thickness of Antarctic ice is about 2,160 meters (7,087ft), though in some areas it is significantly deeper. For example, in the Terra Adeli region, the ice sheet reaches a thickness of approximately 4,776 meters (15,670ft) - nearly five kilometers of solid ice accumulated over millions of years.
Surprisingly, the North Pole is warmer than the South Pole. It is at sea level, while the South Pole is 2.8 km (9,186ft) above sea level; moreover, the North Pole receives sunlight for a week longer than the South Pole.
