Population

About 4,000 on scientific bases in the short
summer 1,000 total in winter, around 30,000 summer
tourists – and this place is 1.4 x bigger than the USA! There are
NO permanent residents and NEVER has been a native population.

Discovery and Exploration

Antarctica was imagined by the ancient Greeks, but
not even seen until 1820.
The first
time anyone set foot on Antarctica was in 1821.
The first year-round occupation – overwintering
– was in 1898.
The South Pole was first reached in 1911.

Climate

3 factors rule in Antarctica – cold, wind and
altitude.
Antarctica holds the world record for each of these
three things.
The temperature falls as you
leave the coast as the continent slopes upwards and temperature
falls as you go higher.
Temperature:Lowest recoded on earth – Vostok station -89.2°C / -128.6°F

Average summer temperature at South Pole -27.5°C / -17.5°F

Average winter temperature at South Pole -60°C / -76°F

Wind:

Mawson station in Antarctica is the windiest place on earth.

Average wind speed:

37 kmh / 23 mph

Maximum recorded gust:

248.4 kmh / 154 mph

Landforms Antarctica has many
landforms – it’s a continent! But for the benefit of your
geography teacher, here’s a few main ones:
