Antarctic
hideThe Antarctic (pronounced /ænˈtɑrktɪk/) is the region around the Earth's South Pole, opposite the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica and the ice shelves, waters and island territories in the Southern Ocean situated south of the Antarctic Convergence. The region covers some 20% of the Southern Hemisphere, of which 5.5% (14 million km2) is the surface area of the continent itself.
