Where was Antarctica 250 million years ago?
Approximately 250 million years ago during the Triassic period, Antarctica was part of the supercontinent of Pangea. During this time, all of the continents were assembled into a large and continuous land mass that was free of polar ice and all of the oceans were combined into one large oceanic mass (Panthalassa).
What was the climate like in Antarctica?

How warm has Antarctica ever been?
The hottest-ever temperature recorded in Antarctica has been confirmed by leading climate scientists with the United Nations. The temperature of 18.3C in the southern polar region, one of the fastest-warming places on the planet, was announced by the World Meteorological Organisation (WMO).
How Antarctica got its ice?
Ice enters the sheet through precipitation as snow. This snow is then compacted to form glacier ice which moves under gravity towards the coast. Most of it is carried to the coast by fast moving ice streams. The ice then passes into the ocean, often forming vast floating ice shelves.

Antarctica doesn’t belong to anyone. There is no single country that owns Antarctica. Instead, Antarctica is governed by a group of nations in a unique international partnership. The Antarctic Treaty, first signed on December 1, 1959, designates Antarctica as a continent devoted to peace and science.
What is the climate of Antarctica before?

When did it rain in Antarctica?
Antarctica is a desert. It does not rain or snow a lot there. When it snows, the snow does not melt and builds up over many years to make large, thick sheets of ice, called ice sheets. Antarctica is made up of lots of ice in the form of glaciers, ice shelves and icebergs.
