Antarctica is one of six continents on our planet, located in the Southern hemisphere, encapsulating the South Pole. About 98% of Antarctica is covered by ice that averages at least 1 mile in thickness and on average it is the coldest and windiest continent, and has the highest average elevation of all the continents. Although the existence of Terra Australis, the mysterious Southern Land, was theorized since the 1st century AD, it was first spotted only in 1820, however it remained unexplored for the rest of the century, due to its hostile environment, lack of valuable resources and complete isolation. Learn more about Antarctica, its geology, climate, territorial claims of various countries on the continent, as well as their research stations in this book.
