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