9. Page 9 Antarctica is bordered by the waters often known as the Antarctic Ocean(or Southern Ocean). Here the southern parts of the Atlantic, Pacific, and the Indian oceans meet. Antarctica means “opposite to the Arctic,” Earth’s northernmost region.

Antarctic Iceberg Icebergs are free-floating chunks of glaciers, particularly common in the polar regions. Although they are often spectacular, these ice formations pose a twofold problem for navigators: Icebergs may be 90 percent bigger than they appear from the surface, and it is impossible to map their presence because they are constantly moving.

12. Page 12 Red Snow Algae on Snowfields on the Antarctic Peninsula Algae, the most primitive plants, are adapted for a wide range of environmental conditions. The red cast of the snow in certain parts of the Antarctic Peninsula is due to the presence of a species of red algae that lives out its entire life on snowfields and glaciers.

14. Page 14 Antarctica is the icy continent at the South Pole. It is covered by permafrost (permanently frozen ground), is surrounded by water, and is about 1 1/2 times larger than the United States. The world's largest desert is on Antarctica. 98 percent of the land is covered with a continental ice sheet; the remaining 2 percent of land is barren rock. Antarctica has about 87% of the world's ice. Geography

15. Page 15 Climate The South Pole is the coldest, windiest, and driest place on Earth. The coldest temperature ever recorded on Earth was at the South Pole; it reached -128.6°F (-88.0°C)!

16. Page 16 People There are 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.

17. Page 17 Location Antarctica hasn't always been located at the South Pole. It has drifted, like the other continents, and has ranged from the equator (during the Cambrian period, about 500 million years ago) to the South Pole. During the time of the dinosaurs (the Mesozoic Era, about 65 million to 248 million years ago), Antarctica was more temperate and housed dinosaurs and many other life forms. Now, there is very little indigenous life

23. Page 23 The sea around Antarctica, is full of living creatures. Krill, a microscopic shrimp-like creature Earless seals do not have flaps over their ears. Their heads look smooth. The hind, or back, flippers of earless seals face behind them so that they have an awkward movement on land.

24. Page 24 Eared seals and sea lions have external (outside) ear flaps, which is how they get their name. Eared seals and sea lions can rotate their hind feet forward and can therefore propel themselves forward with considerable speed. Unlike the earless seals, they are quite agile on land. The front flippers are used on land to prop themselves up, and in the water to swim with

26. Page 26 Elephant seals breed in groups called harems. The strongest males each control a harem of up to 50 females. Once a harem grows to more than this, the dominant male will allow some less strong males to live with the harem.

It blocks a lot of ultraviolet light that is harmful to the skin and could cause skin cancer. However the ozone layer over Antarctica is being destroyed. Scientists blame this destruction on Chlorofluorocarbons, or CFC's.
