Blake's Powerpoint

  1. 1. Antarctica By Blake
  2. 2. <ul><li>Antarctica is an amazing place. It is the 5 th largest continent on earth. It is massive it holds about ¾ of the worlds fresh water. It is the coldest, windiest and driest place on earth. </li></ul>Introduction
  3. 3. <ul><li>There have been a lot of people who have explored Antarctica, but the top three famous explorers are Roald Amundsen, Earnest .H .Shackleton and Robert Falcon Scott. </li></ul>Famous Explorers
  4. 4. <ul><li>Roald Amundsen was born in Norway. His first experience of Antarctica was in 1899 on Belgica Expedition. He was the first man to reach the South Pole with his crew. He set of for the South Pole from Norway in 1910 and had supplies for 2 years with nearly 100 Greenland sled dogs to get to the South Pole quicker. He died at the age of 55 years old but no one knows where. </li></ul>Roald Amundsen
  5. 5. Roald Amundsen
  6. 6. <ul><li>Sir Ernest Shackleton was born in Kilkea, Ireland. His first time in Antarctica was when he was the third officer on Captain Scott’s discovery expedition which was from 1901 to 1904. He went back to Antarctica as leader of the Nimrod expedition. In 1909 he and three of his crew made a Southern March which made a record of Farthest South latitude 88 23’s. He died at the age of 47 in Georgia Island. </li></ul>Ernest.H. Shackleton
  7. 7. Ernest Shackleton
  8. 8. <ul><li>Robert Falcon Scott was born in the year 1868, Plymouth in England. He was an explorer who led two expeditions to Antarctica. He led the Discovery expedition which was from 1901 to 1904 and the Terra Nova expedition from 1910 to 1912. He had a crew of 5 which made it to the South pole in 1912, after Roald Amundsen. On the way back to the ship Robert and his crew died at the Ross Ice Shelf in 1912. </li></ul>Robert Falcon Scott
  9. 9. Robert Falcon Scott
  10. 10. <ul><li>Antarctica is massive and amazingly thick. It is about 1 and a 1/2 times bigger than the USA. The of it is about 14 million km2 or 280,000 mi2. </li></ul>Size
  11. 14. <ul><li>There is not a lot of animals in Antarctica so the food chain is not that big. The food chain is:1.Killer whales, 2.Other Whales, Seals, Fishes and Penguins, 3.Krill, Shrimp, Small Fishes and Squid 4.Plankton. Those are mostly all the animals in Antarctica. </li></ul>Antarctica's Food Chain
  12. 16. <ul><li>The South Pole is at the bottom of the Earth. It is opposite of the North Pole. There is a station in the South Pole. It is nearly right in the middle of Antarctica it owned by the USA. South Pole is probably is the coldest place in Antarctica. </li></ul>South Pole
  13. 17. <ul><li>The coldest ever recorded in Antarctica was at -89.2 degrees C in 1983 at a Russian research station. The coldest it gets is between -80 and -90 degrees C. The hottest temp is about 5 degrees C in the coastal parts in Summer. </li></ul>Climate
  14. 18. <ul><li>There is not a lot of plants in Antarctica because of the weather and the soil. So the only ones are mosses ,algae and Fungi. There is about 700 types of algae in Antarctica. </li></ul>Plants
  15. 22. <ul><li># A lot of countries have made research stations in Antarctica but none of them on Antarctica. </li></ul><ul><li># If Antarctica's ice sheets melted the worlds ocean would rise by 60 to 65m higher. </li></ul><ul><li># Antarctica is the best place in the world to find meteorites. </li></ul><ul><li># It has been guessed that during the feeding season of Antarctica a full grown blue whale eats about 4 million krill per day that would be about 4 tons, this daily feeding for whales is food for a human for about 4 years. </li></ul><ul><li># A group of krill has been recorded up to 10 million. </li></ul><ul><li># Antarctica was never seen until 1820 . </li></ul><ul><li># Maximum wind Recorded was 248.4 kmph. </li></ul><ul><li># Antarctica holds 90% of the worlds ice. </li></ul>Interesting Facts
  16. 23. <ul><li>There are not a lot of animals in Antarctica but my top three favourites are: Killer Whale, Weddell Seal and Emperor Penguins. I like them because they look nice and they’re interesting. </li></ul>Animals
  17. 24. <ul><li>Killer Whales are on the top of the food chain, they eat nearly all the animals in Antarctica. Killer Whales have teeth unlike other whales. They eat fishes, squids, penguins, seals and other whales including the biggest whale of them all, the Blue Whale. When Killer whales are born they are born in a group and they stay with that group for the rest of their lives. A fully grown male Killer Whale is about 9.75m and a female is about 8.5m. They are black and white. </li></ul>Killer Whale
  18. 26. <ul><li>Weddell Seals are big animals, the male and the female is about 3m long and weigh about 400 to 500kg. They are grey, black and white. They are carnivores, they mainly eat fish, squid, octopus and prawns. They can hold there breath under water for 45min and can go as deep as 720m in search for food. Babies are born in September and October. </li></ul>Weddell Seal
  19. 28. <ul><li>Emperor Penguins are the biggest of all the different types of penguins. They are about 115cm tall and can live up to about 40 years. They weigh from 23 to 40 kg. Their colonies range from a couple of hundreds to about 20,000 pairs. They are the only animals that breed during the winter seasons of Antarctica. When the weather is to cold for them they all huddle up to keep each other warm. The egg of an Emperor Penguin weighs about 450g. The average depth they can get under water is about 150 to about 250m but deepest ever recorded was 565m. They usually can stay under water for about 3 to 6 minutes but longest ever recorded was 22 minutes. </li></ul>Emperor Penguin
  20. 30. <ul><li>There are a lot of reasons why Antarctica is getting destroyed. It is happening because of holes in ozone layer, Green House Gases, Global Warming and Marine Pollution. It is happening because when carbon dioxide is released from cars and planes it goes all the way up to the ozone layer and the carbon dioxide weakens the ozone layer. The ozone layer makes the suns ray less powerful on our skin and when the ozone layer is weakened the suns ray is more powerful which makes places like the Antarctic and the Arctic melt. </li></ul>What is destroying Antarctica
  21. 31. Ice breaking off Antarctica
  22. 32. <ul><li>To help we can use cars and planes less. If we dropped using carbon dioxide by 50% all around the world the ozone layer will be able to heal itself and return to normal with no holes in it. To help choose cars that reduce carbon dioxide, solar panels are also a good choice because they don’t use any electricity at all. </li></ul>How can we prevent Antarctica Melting and Breaking
  23. 33. <ul><li>We need to save Antarctica because if it melts a lot of people will die because of rising waters. Also if only the western part of Antarctica melt the water will rise all around the world by 20 feet. If it melts, there will be Tsunamis, Earthquakes and Cyclones. Another reason is that Antarctica is a wonderful place. So we should try an help save Antarctica. </li></ul>Why Should We Help Save Antarctica
