Antarctica

Antarctica is the southernmost continent on Earth, located almost entirely within the Antarctic Circle. It is the fifth-largest continent in terms of area, and it is the coldest, driest, and windiest continent. The majority of Antarctica is covered by ice, some of which is more than 4 kilometers thick. The continent is also home to a diverse range of wildlife, including penguins, seals, and various species of birds.
