NettetThe climate of Antarctica is the coldest on Earth.The continent is also extremely dry (it is a desert), averaging 166 mm (6.5 in) of precipitation per year. Snow rarely melts on most parts of the continent, and, after being compressed, becomes the glacier ice that makes up the ice sheet. Weather fronts rarely penetrate far into the continent, because of the … Nettet27. apr. 2024 · The coldest, the windiest, the driest: the continent of Antarctica is a place of extremes.
