Antarctica is bigger than Europe and almost double the size of Australia.
Most of Antarctica is covered in ice over 1.6 kilometers thick (1 mile).
Because it experiences such little rain, Antarctica is considered a desert.
The name ‘Antarctica’ comes from a Greek word meaning ‘opposite to the north’.
Around 90% of the ice on Earth is found in Antarctica.
Antarctic hair grass and the Antarctic Pearl wort grows on Antarctica peninsula. They are the only two flowering plants, which grow south of 60° latitude.
Around 90% of the ice on Earth is found in Antarctica.
Ecosystem
All the life in Antarctica has
to learn to live on the ice. All of the life in Antarctica revolve and have to adapt to the icy environment.

Flappy Bird!
The Temperature in Antarctica during the winter months it is -70˚C and during the warmer months it is -30˚C.
There is almost no rainfall, but almost always windy. In the warmer months there is always sunlight so it's always bright. But in the winter months there is almost no sunlight. There is no good soil, but sometimes plants can grow in some places/areas.
Because Antarctica is on the bottom of the earth, there are only two seasons- summer and winter. In the winter it is dark and very cold all day but in the summer season it is always bright but little bit cold.
In summer when its slightly hotter, the plankton and other microscopic organisms will float in great groups near the surface of the water and they are the base of the ocean food chain. It can grow quickly and produce food for the entire ecosystem.
The whole food system depends on plankton.
