Antarctic Geography Stats

Definitions

  • Area > Comparative: The area of various small countries expressed in comparison to various areas within the United States of America.
  • Area > Comparative to US places: This entry provides an area comparison based on total area equivalents. Most entities are compared with the entire US or one of the 50 states based on area measurements (1990 revised) provided by the US Bureau of the Census. The smaller entities are compared with Washington, DC (178 sq km, 69 sq mi) or The Mall in Washington, DC (0.59 sq km, 0.23 sq mi, 146 acres).
  • Area > Land: Total land area in square kilometres
  • Area > Total: Total area in square kilometers
  • Climate: A brief description of typical weather regimes throughout the year.
  • Coastline: The total length of the boundary between the land area (including islands) and the sea.
  • Elevation extremes > Highest point: Highest point above sea level
  • Elevation extremes > Lowest point: This entry is derived from Geography > Elevation extremes, which includes both the highest point and the lowest point.
  • Geographic coordinates: This entry includes rounded latitude and longitude figures for the purpose of finding the approximate geographic center of an entity and is based on the Gazetteer of Conventional Names, Third Edition, August 1988, US Board on Geographic Names and on other sources.
  • Land use > Arable land: The percentage of used land that is arable. Arable land is land cultivated for crops that are replanted after each harvest like wheat, maize, and rice
  • Land use > Other: The percentage share of used land that is not arable or under permanent crops. This includes permanent meadows and pastures, forests and woodlands, built-on areas, roads, barren land, etc.
  • Location: The country's regional location, neighboring countries, and adjacent bodies of water.
  • Natural hazards: Potential natural disasters.
  • Natural resources: A country's mineral, petroleum, hydropower, and other resources of commercial importance.
  • Terrain: A brief description of the topography
STAT AMOUNT DATE RANK HISTORY
Area > Comparative slightly less than 1.5 times the size of the US 2013
Area > Comparative to US places slightly less than 1.5 times the size of the US 2008
Area > Land 14 million sq km 2008 2nd out of 235
Area > Total 14 million sq km 2013 2nd out of 251
Climate severe low temperatures vary with latitude, elevation, and distance from the ocean; East Antarctica is colder than West Antarctica because of its higher elevation; Antarctic Peninsula has the most moderate climate; higher temperatures occur in January along the coast and average slightly below freezing 2013
Coastline 17,968 km 2014 10th out of 242
Elevation extremes > Highest point Vinson Massif 4,897 m 2013
Elevation extremes > Lowest point Bentley Subglacial Trench -2,540 m 2013
Geographic coordinates 90 00 S, 0 00 E 2013
Land use > Arable land 0.0 2013 215th out of 246
Land use > Other 100% 2011 1st out of 245
Location continent mostly south of the Antarctic Circle 2013
Natural hazards katabatic (gravity-driven) winds blow coastward from the high interior; frequent blizzards form near the foot of the plateau; cyclonic storms form over the ocean and move clockwise along the coast; volcanism on Deception Island and isolated areas of West Antarctica; other seismic activity rare and weak; large icebergs may calve from ice shelf 2008
Natural resources iron ore, chromium, copper, gold, nickel, platinum and other minerals, and coal and hydrocarbons have been found in small noncommercial quantities; none presently exploited; krill, finfish, and crab have been taken by commercial fisheries 2013
Terrain about 98% thick continental ice sheet and 2% barren rock, with average elevations between 2,000 and 4,000 meters; mountain ranges up to nearly 5,000 meters; ice-free coastal areas include parts of southern Victoria Land, Wilkes Land, the Antarctic Peninsula area, and parts of Ross Island on McMurdo Sound; glaciers form ice shelves along about half of the coastline, and floating ice shelves constitute 11% of the area of the continent 2013

Did you know

  • Canada has a longer coastline than the USA, the European Union, Australia and Antarctica combined.

  • If you thought Antarctica was inhospitable, think again - its land area is only ninety-eight percent ice. Reassuringly, the other 2% is categorised as "barren rock".
