McMurdo Dry Valleys, Landsat 7 imagery acquired on December 18, 1999 The Dry Valleys are so named because of their extremely low humidity and lack of snow or ice cover. They are also dry because, in this location, the mountains are sufficiently high that they block seaward-flowing ice from the East Antarctic Ice Sheet from reaching the Ross

The Antarctic continental shelf is a submerged piece of the Antarctic continent that underlies a portion of the Southern Ocean — the ocean which surrounds Antarctica. The shelf is generally narrow and unusually deep, its edge lying at depths averaging 500 meters (the global mean is around 100 meters), with troughs extending as far as 2000 ...
The dominant grassland is the tussock. These grasses get to be 2 m (6 ft 7 in) high, so they provide habitat for many mammals. [25] Of the 14,000,000 km 2 (5,400,000 sq mi) of land that makes up Antarctic, less than 2% of it does not have snow or ice. [26] One example of a type of vegetation is a crustose lichen. These lichens are found in ...
