Captain
James Cook crossed the Antarctic Circle in 1773 but the Antarctic
continent itself was not discovered until the 1820's. |
 |
It is the coldest,
driest and highest continent on earth. |
 |
It is the most inhospitable place
on earth and is the windiest with Katabatic winds caused by
heavy, cold air flowing downhill from the high interior reaching
speeds of 100mph |
 |
It is the fifth largest continent
in the world extending over nearly 5.4 million square miles
and is larger than either Australia or Europe. |
 |
The Antarctic covers approximately
9% of the earth’s surface. |
 |
Antarctica has the coldest recorded
temperature in the world at below minus 89°C. By comparison
a domestic deep freeze operates at a temperature of no colder
than minus 15°C. |
 |
Ice has covered 99% of the Antarctic
continent for 15 million years and is up to 4 kilometres thick
in places. |
 |
It is a cold desert with an average
snowfall of only 150mm. |
 |
In winter the Southern Ocean
which surrounds Antarctica freezes, effectively doubling the
size of the continent. |
 |
The Antarctic is devoid of wildlife
except around some of its shores. |
