Transcript

  • 1. Antarctica – Coldest and Least Friendly Place on Earth<br />
  • 2. Geography - Antarctica<br />Icy continent at the South Pole. <br />Covered by permafrost (permanently frozen ground)<br />Surrounded by water<br />About 1 1/2 times larger than the United States<br />Has the world&apos;s largest desert is on Antarctica<br />98% of the land is covered with ice<br />Has about 87% of the world&apos;s ice. <br />
  • 3. Climate – Antarctica<br />Coldest, windiest, and driest place on Earth. <br />The coldest temperature ever recorded on Earth was at the South Pole; it reached -128.6°F ! <br />On average, most of Antarctica gets less than 2 inches of snow fall each year.<br />
  • 4. Why do you think that Antarctica is so much colder than the Arctic?<br />
  • 5. Antarctica is a continent surrounded by an ocean which means that interior areas do not benefit from the moderating influence of water.<br />With 98% of its area covered with snow and ice, the Antarctic continent reflects most of the sun&apos;s light rather than absorbing it. <br />During the winter, the size of Antarctica doubles as the surrounding sea water freezes, effectively blocking heat transfer from the warmer surrounding ocean. <br />Antarctica has a higher average elevation than any other continent on Earth which results in even colder temperatures.<br />
  • 6. ICE<br />Thickest ice is 15,000 feet thick. That’s <br />About 5,000 feet in a mile<br />Estimate how many miles thick the ice can be in Antarctica.<br />How thick was the ice at your house a few weeks ago?<br />
  • 7. People - Antarctica<br />No permanent human residents (because of the extreme weather, which includes freezing temperatures, strong winds, and blizzards).<br />There are about 4,000 seasonal visitors to Antarctica (mainly scientific expeditions).<br />
  • 8. How about some Antarctica jokes ?<br />HA HAHAHAHAHA<br />
  • 9. Q: What&apos;s a penguin&apos;s favorite salad? <br />
