Describe antarctica's qualities and explain why this unique continent would attract scientific study.

Antarctica is the continent around the South Pole of the Earth. It is surrounded by the Atlantic Ocean, the Indian Ocean and the Pacific Ocean, although all sea areas around Antarctica, south of the 60th parallel, are now referred to as the Southern Ocean (or Antarctic Ocean).

Antarctica is almost completely covered with an ice sheet and the continent is the coldest area on Earth. The lowest temperature ever measured in a weather station was at the Vostok station at 1000 kilometers from the South Pole: −89.2 ° C.

Every year, scientists from 27 different nations direct non-reproducible experiments elsewhere in the world. During the summer more than 4,000 scientists operate the research bases; This number decreases to almost 1,000 in winter. Researchers include biologists, geologists, oceanographers, physicists, astronomers, glaciologists, and meteorologists. Geologists study the tectonic plates, meteorites of outer space, and resources from the erosion of the supercontinent Gondwana. Glaciologists in Antarctica deal with the study of the history and dynamics of floating ice, seasonal snow, glaciers, and ice sheets. Biologists, in addition to examining wildlife, study how they affect the hard temperatures and the human presence in the adaptation and survival of a wide variety of organisms. Doctors have uncovered the spread of viruses and the body's response to extreme seasonal temperatures.
