Antarctica is covered by an ice sheet about four kilometers thick. Under the ice it is mostly land, although the ice shelves are glossing over the ocean. The Trans antarctic Mountains divide the land between East Antarctica in the Eastern Hemisphere and West Antarctica in the Western Hemisphere. Antarctica has some important features hidden by the ...
Antarctica was formed by the breaking of the Gondwana supercontinent. Scientists say Antarctica used to be much farther from north and much warmer, moving to where it is now through continental drift. From 2010 to 2015, scientists collected fossils of frogs, water lilies, and shark and ray teeth, showing that these life forms used to live on Antarc...
Plants
Few land plants grow in Antarctica. This is because Antarctica does not have much moisture (water), sunlight, good soil, or a warm temperature. Plants usually only grow for a few weeks in the summer when penguins produce the most feces. However, moss, lichen and algae do grow. The most important organisms in Antarctica are the planktonwhich grow in the ocean.
Animals
One important source of food in the Antarctic is the krill, which is a general term for the small shrimp-like marine crustaceans. Krill are near the bottom of the food chain: they feed on phytoplankton and to a lesser extent zooplankton. Krill are a food form suitable for the larger animals for whom krill makes up the largest part of their diet. Whales, penguins, seals, and even some of the birdsthat live in Antarctica, all depend on krill. Whales are the largest animals in the ocean, and in...
For a long time, people had believed that there was a great continent in the far south of Earth. They thought this Terra Astral-is would "balance" the lands in the north like Europe, Asia and North Africa. People have believed this from the times of Ptolemy (1st century AD). He suggested this idea to keep the balance of all known lands in the world...

The Antarctic Convergence is an uneven line of latitude where cold, northward-flowing Antarctic waters meet the warmer waters of the world’s oceans. The Antarctic covers approximately 20 percent of the Southern Hemisphere. Antarctica is the fifth-largest continent in terms of total area. (It is larger than both Oceania and Europe.)
From Simple English Wikipedia, the free encyclopedia. The Antarctic Region. The Antarctic is the area around the Earth 's South Pole. Its opposite is the Arctic region which is around the North Pole. The Antarctic includes the continent of Antarctica and the ices, waters and islands in the Southern Ocean. [1]
Antarctica is the Earth's southernmost and least populous continent. It is on the South Pole. It is almost entirely south of the Antarctic Circle. Around Antarctica is the Southern Ocean. It is the fifth-largest continent in area after Asia, Africa, North America, and South America. About 99% of Antarctica is covered by ice. This ice averages at least 1.6 kilometers (1.0 miles) thick.
