At the world's southernmost reaches the land is buried under a layer of ice that can reach thousands of meters thick.

 

Though Antarctica is really really chilly it is considered a desert because it receives very little rain or snowfall. The small amount of snow that does fall does not melt but builds up over hundreds and thousands of years to form large thick ice sheets.

 

NASA uses satellites to study the ice on Antarctica and how the continent is changing. Scientists want to know how changes in Earth?s climate are affecting Antarctica?s ice sheets.

 

Antarctica is the only continent with no permanent human habitation. There are however permanent human settlements where scientists and support staff live for part of the year on a rotating basis.

Because Antarctica surrounds the South Pole it is theoretically located in all time zones. For practical purposes time zones are usually based on territorial claims or the time zone of a station's owner country or supply base.

 

Antarctica the world?s southernmost continent is almost wholly covered by an ice sheet and is about 5.5 million square miles (14.2 million square km) in size.

 

Most of Antarctica is covered by the Antarctic ice sheet with an average thickness of 1.9 km (1.2 mi). Antarctica is on average the coldest driest and windiest of the continents and has the highest average elevation. It is mainly a polar desert with annual precipitation of over 200 mm (8 in) along the coast and far less inland.
