Transcript of Antarctica

*Antarctica* The Emperor Penguin The emperor penguin is the tallest and heaviest of all living penguin species. These flightless animals live in the Antarctic ice and in the surrounding waters. They have colourful feathers around their necks.
Habitat:the Emperor penguin lives in colonies on ice in Antarctica.
Feathers: Emperor Penguins have shiny, waterproof feathers that help keep their skin dry. they havemore feathers than most other birds
Diet: Emperor Penguins are meat eaters who hunt in the sea. They eat fish and squid *Oceans surrounding Antarctica: southern ocean, Indian ocean

*countries close to Antarctica: Australia, New Zealand and Brazil

Average thickness of ice: 1.6 meters
Highest temperature: 15°C
Lowest temperature: -89.2°C Antarctica Information James Cook captain James Cook was a navigator born on 27th October 1728in Marton, Cleveland, Yorksville,England. James Cook was a british explorer and navigator famous for his 3 great voyages of exploration in the south pacific ocean and the north American coastal waters.
Death: 14 February 1779
spouse: Elizabeth Batts *Occupation: Explorer and navigator
*Born: October 27, 1728 in Marton, England.
*Died: February 14, 1779
*Best known for: Exploring the South Pacific. James Cook visits to Antarctica captain James cook went to Antarctica to search for the southern continent and to test a version of the John Harrison chronometer, commanding the ship resolution he crossed the waters of Antarctica and crossed the antarctic circle on the 17th January 1773. The ice and the freezing cold prevented him from crossing the region any further. James cook crossed the Arctic circle on 30th January 1774 once again he got stopped by a thick pack of ice that prevented him from further exploration and progression. James cook achievements were
*sailed further than any other explorer
*discovered south Georgia island.
*crossed the Arctic circle twice
*James Cook commanded the Envadour on an expedition Achievements in Antarctica James cook Information * research shows that tourism in Antarctica is steadily increasing and if an influx of tourists were to occur fragile vegetation would be destroyed. Nesting and breeding grounds would also be disturbed Tourism in Antarctica Impacts on our Environment *contaminating the soils and discharging sewage out to the sea and leaving rubbish in even the most remote parts Impacting animal species *harvesting some Antarctic species to the verge of extinction for economic benefit
*killing and disturbing other species Antarctica is often thought of as a pristine land untouched by human disturbance. Unfortunately this is no longer the case. For a little more than 100 years people have been traveling to Antarctica and in that short time most parts have been visited and we have left more than just footprints. Tourism Antarctica has six months of daylight and six months of darkness. The earth revolves around the sun and tilts on it's axis. During the winter, Antarctica is tilted away from the sun, causing it to be dark. For the half of the year that is summer, Antarctica is facing the sun and getting more of its direct rays. Antarctica climate temperature The lowest temperature ever recorded in Antarctica was -129ºF. The warmest temperature ever recorded in Antarctica was 59ºF. The average summer temperature is 20ºF. The average winter temperature is -30ºF. oil spills Oil spills are an increasing form of pollution in Antarctica as a result of increasing shipping activity in the region. Antarctica map * animal extinction is another severe problem. Penguins have suffered greatly in the hands of humans. many penguins have been slaughtered for their skin and now also for their blubber. Fur seals have almost been wiped out by sealing animal extinction *Climate change is the greatest long-term threat to the region. With some parts of Antarctica experiencing significant ice retreat and collapse of ice shelves along the Antarctic Peninsula, there can no longer be any doubt that the Antarctic is getting warmer.
*If the climate continues to warm, scientists predict that krill populations could be devastated, undermining the entire southern polar food chain. Climate Change * Global warming is threat to the entire Earth. Whether global warming is the result of man's activities or part of the natural cycle of the Earth, it is still a threat to the Antarctic ice shelves.

*The ice shelves in the southern part of the Antarctic Peninsula appear to be disappearing because of global warming and if we don’t do something now global warming can have major effects on Antarctica. Global warming The earth's protective atmospheric layer, called the Ozone, is gradually being depleted, resulting in a gradual melting of Antarctica's ice sheets. If ice sheets were to melt, the world's ocean would rise as much as 200 to 210 feet and that will greatly endanger the safety of human beings and animals. The ozone layer My opinion I think that all these severe problems in Antarctica were caused from tourism.
If we did not let tourists visit and explore Antarctica all these problems would have never happened
I think that tourism should either be canceled or it should only be a 1 day visit Antarctica information report *By: Zainab Bonab* http://www.discoveringantarctica.org.uk/ Bibliography Size: 13,209,000 sq km, 5,100,021 sq miles http://www.worldatlas.com/webimage/countrys/an.htm http://www.coolantarctica.com/Antarctica%20fact%20file/science/global_warming2.htm http://www.livescience.com/21677-antarctica-facts.html http://www.mentalfloss.com/blogs/archives/113128 *In Antarctica the sun sets in March and rises in October.
*The first person who set foot on Antarctica was Henry Bull in 1895.
*plants grow in Antarctica in the ie free areas.(only about 2 percent of Antarctica is ice free. Antarctica facts Antarctica is the highest, driest, windiest, emptiest, coldest place on earth. *Antarctica is the driest place on earth in some places it has not rained for thousands of years. *scientists work on all different experiments in Antarctica. interesting facts The coldest recorded temperature was -89.2°C at the Russian base station Vostok in 1983.
Scientists have discovered fossils of dinosaurs and trees in Antarctica, which shows it was once warm and covered in forests and wildlife.
In the middle of summer it is light all day, while in winter there is total darkness.
Antarctica receives so little moisture that is classified as a cold desert. There are active volcanoes on Antarctica. Mount Erebus constantly spurts hot lava onto the ice. An ice sheet covers around 98% of Antarctica’s surface. It contains 90% of the world’s ice and 70% of the world’s fresh water. At its thickest point, the ice sheet is 4.7km deep. Antarctica is nearly twice as big as Australia, and in the winter its frozen ocean doubles in size.
