Antarctica

Earth’s southernmost continent, it contains the geographic South Pole and is situated in the Antarctic Region of the Southern Hemisphere. Almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean.
The name “Antarctica” comes from a Greek compound word meaning “opposite to the Artic” or “opposite to the north”.

Antarctica not only includes the emerged pieces of land but also the marine regions limited by the Antarctic Polar Front or Antarctic Convergence (an irregular line that joins the points where the cold waters of the Antarctica circumpolar current meet the warmer waters of the North). It is not a “fixed” limit, it changes with the seasons and forms a significant biological boundary.
