Transcript of Antarctica

ANTARTICA Climate Antartica is the coldest continent on earth. In winter, Antarctica doubles in size and temperatures can reach below -40°C!
Antarctica has six months of daylight and six months of darkness, in the winter it is dark because the earth is turned so that no sunlight reaches Antartica.In summer Antartica faces the sun, so the light reaches it. Bibliography

In Antartica, nearly all animals need the ocean to survive. For example the blue whale, sea gulls, penguins and many more, all eat krill.

Krill are tiny animals that live in the sea, and look similar to shrimp. They are basicly at the bottom of the food chain.

Did you know that there is only one animal on antartica that doesn't rely on the ocean to survive? These creatures are called springtails, and are so small, that you need a microscope to see them properly, they are only around 6mm long!

Albatross chicks weigh nearly twice as much as their parents do, so while growing up to be able to fly, they have to lose a lot of weight! When they are fully grown, they have a wing span up to 3 metres. Food Chain The food chain in the picture shows which animals eat what, right at the bottom are Krill. They reproduce very quickly, so currently their only threat to being wiped out is overfishing, which sadly happens a lot.If they do get wiped out, the animal that eat them will starve and the whole food chain will collapse! The same thing would happen if any other animal in the chain was wiped out. www.naturfoto-cz.de/giant-springtail:tetrodon
thespokedb.wordpress.com Treaty The Antarctic Treaty was made in Washington,
1959, by scientists from The United Kingdom,
South Africa, Belgium, Japan, The USA, Norway,
France, New Zealand, Russia, Argentina,
Australia and Chile. The Antarctic treaty
protects the animals and environment of
Antarctica. It forbids many things to be done
in Antarctica, such as: weapon testing,
dumping radioactive waste and nuclear
explosions.


Transport Land Air Water http://www.classroom.antarctica.gov.au/7-international/7-1-antarctic-treaty On land in Antarctica,
people usually travel
by foot, wearing snow
shoes, or by skis. If
they travel longer
distances, the journey
would probably be made
on snowmobile.
Snowmobiles look similar
to jet skis, but with
skis at the front and
a continuous track at
the back.



Aeroplanes and helicopters
are common transportation
vehicles in Antarctica,
which has a total of 20
airports, and 27 helicopter
landing pads.
Antarctica has only 1
harbour, at McMurdo
station. All food and other supplies are brought to Antarctica
by boat. Water transport is very important there also because each year many touring boats, sailing ships, and motor vessels, visit the Antarctic shores. http://dev.coastalvoyage.com/images/10AntarcticaSouthGeorgia digitaljournal.com sheriff.co.warren.ny.us Bases There are 4 Australian bases in Antarctica: Casey, Davis, Mawson and Macquarie island. Scientists travel to these bases for the summer,or the winter, because it is too cold to stay in Antarctica for a longer period of time. In the pictures you can see how colourful
the stations are, they are like this is so that it is easier for boats, planes and other scientists to spot the stations during the night or blizzards.

Global warming is happening everywhere, but what happens in Antarctica will effect the whole planet. If the ice-bergs and ice sheets melt, then the sea levels will rise. For the pat 50 years, Antarctica's temperatures have been rising by 0.05°C each decade.

Global warming will also affect Antarctica's animal population. If ocean temperatures rise, small sea creatures like phytoplankton, krill and small fish will not be able to survive in the warm water, this will cause the whole food chain to collapse.
