Transcript of Untitled Prezi

By Charlotte Freeborn Antarctica Antarctica is in the south pole. It is surrounded by the southern ocean, Antarctica is 14,000,000 square metres. In 1773 Captain James Cook sailed around Antarctica with his crew, they sailed around on the ' Resolotion' and the 'Adventure' between 1773 and 1775. Three people were the first to sight Antarctica in 1820 they were : Fabian Von Bellinghausen, Edward Bransfield and Natheniel Brown Palmer. The first landing on Antarctica was more than a year later by Captain John Davis on the 7th of February 1821. After this many other people have explored the Antarctic these include : James Clark Ross, Robert Falcon Scott, Ernest Shakleton and Roald Amundsen. Roald Amundsen was the first to reach the South Pole. In Antarctica there are barely any plants that can survive these harsh conditions, Some of the plants are quite an everyday kind of plant, so it is normal to see some them in your garden and the plants are: algae, mosses, liverworts, lichens and a bit of fungi. The single land mass of Antarctica is about the size of Australia, Greater Antarctica is made of older rocks whereas Lesser Antarctica is made of younger and more volcanic rocks. In Lesser Antarctica there is a mountain called : Mount Erabus and its the southernmost active volcano on Earth. Flora Exploration Location General Land forms and Geography Bases and Location of Bases Antarctica is not owned by any countries, but some major countries have bases there for scientific studies. These countries are: The United Kingdom, Australia, New Zealand, France, Norway, Argentina, Chile, Japan, Russia and the USA. There are four Australian bases in Antarctica and they are : Mawson, Davis, Casey and Maquarie Island. I have shown the location of the bases on my map. Territories Seasons There are 2 seasons in Antarctica, a short, cold Summer and a long colder Winter. Surprisingly Antarctica is the coldest, driest desert in the world. Part of the reason why it is so cold in Antarctica is because it is so far away from the equator so therefore the Sun. Climate The coldest temperature it has reached in Antarctica (ever recorded) is about -88.2 degrees celsius, sometimes the winds can reach over 300 km per hour. In Antarctica the average temperatures are about -12 degrees celsius around where ground is and up high for example on mountains the average temperature is about -20 degrees celsius. Population The population in Antarctica is mainly of researchers and scientists. Antarctica has no people who permanently live there. Fauna Antarctica has many, many animals, therefore there so many different types of animals and here they are : The seals are : the leopard, the Weddall, the Ross, the Southern Elephant, the Crabeater and the Antarctic fur seal. The underwater animals are : The Orcas (killer whale) and the Blue whale. The birds are : the Antarctic Shag, wandering Albatross and the black-Browed Albatross and the penguins are: The Adel'ie, the Rock hopper, the Emperor and the Chinstrap. There are also many smaller invertibrates and some of them are : midges, mites and tardigrades. Current Concerns The main concerns in Antarctica are : Global Warming, Pollution and the Ozone. The ozone is a huge hole in the Ozone layer of Antarctica, the layer screens out UV radiation from the Sun. The Ozone hole is expected to disappear in 2050. An area of ice 720 feet thick and 1255 square miles in size broke off, The ice which had been there for 12,000 years, took just 35 days to disappear. The chemicals that we pour into the sea can be swept around the world by ocean currents, eventually washing up in the North and South poles, Either that or they can be blown away with air pollution and fall onto the Antarctic's snow. Bibliography Antarctica is divided in to 2 parts they' re called : Lesser Antarctica and Greater Antarctica. Both lesser and greater Antarctica are divided into smaller area, in both parts there are many islands. There are seven nations that have claimed a territory in Antarctica, these nations are : Australia, Argentina, Chile, France, New Zealand, Norway and the UK. Thanks for watching everyone !!!!!!!
