The geography of Antarctica is dominated by its south polar location and, thus, by ice. The Antarctic continent, located in the Earth's southern hemisphere, is centered asymmetrically around the South Pole and largely south of the Antarctic Circle. It is surrounded by the southern waters of the World Ocean – alternatively (depending on source), it is washed by the Southern (or Antarctic) Ocean or the southern Pacific, Atlantic, and Indian Oceans. It has an area of more than 14 million km².
Some 98% of Antarctica is covered by the Antarctic ice sheet, the world's largest ice sheet and also its largest reservoir of fresh water. Averaging at least 1.6 km thick, the ice is so massive that it has depressed the continental bedrock in some areas more than 2.5 km below sea level; subglacial lakes of liquid water also occur (e.g., Lake Vostok). Ice shelves and rises populate the ice sheet on the periphery. Only about 2% of the continent is not covered by ice.

Famous quotes containing the words geography of and/or geography:
“The California fever is not likely to take us off.... There is neither romance nor glory in digging for gold after the manner of the pictures in the geography of diamond washing in Brazil.”
—Rutherford Birchard Hayes (1822–1893)
“Where the heart is, there the muses, there the gods sojourn, and not in any geography of fame. Massachusetts, Connecticut River, and Boston Bay, you think paltry places, and the ear loves names of foreign and classic topography. But here we are; and, if we tarry a little, we may come to learn that here is best. See to it, only, that thyself is here;—and art and nature, hope and fate, friends, angels, and the Supreme Being, shall not absent from the chamber where thou sittest.”
—Ralph Waldo Emerson (1803–1882)
