GLACIERS BRYTON TOLMAN  10 percent of land area on Earth is covered with glacial ice.  Glaciers store about 75 percent of the worlds freshwater.  The largest glacier is the Lambert-Fisher Glacier in Antarctica. 400 kilometer(250 miles)long and 100 kilometers(60 miles) wide. Drains about 8 percent of the Antarctic Ice Sheet.  Glaciers are made up of snow that, over many years compresses into large thickened ice masses. Glaciers flow like very slow rivers.  Types of glaciers: mountain, valley, tidewater, piedmont, hanging, cirque, ice apron, rock, ice shells, ice fields, ice caps, ice streams, and ice sheets glaciers.  References: nsidc.org/cryrosphere/glaciers/quick facts.html

ANIMALS JOEY MORRISON  Penguins: some types of penguins are Emperor, Gentoo  Seals: some types of seals are leopard, crabeater, weddel  Whales: some types of whales are toothed, baleen, humpback  Krill: swarms have about 2 million  There are wandering albatross  There are also Antarctic Skua

GEOGRAPHY TYLER DAY  It makes up most of Antarctic region.  It is in southern region of the world.  It is surrounded by the Antarctic Convergence  It is the fifth largest continent in the world.  There is no countries in Antarctica.  Seven nations have claimed parts of it.  Without ice Antarctica is an archipelago called Lesser Antarctica.  It includes different islands.

THE WINTER/SUMMER TEMPERATURES IN ANTARCTICA MICAH GOFF AND JASMINE NORMAN  The average winter temperature in Antarctica is around -10 Celsius (14 Fahrenheit) to -30 Celsius (- 22 Fahrenheit)  The coldest Antarctica has been is -89 Celsius (-128 Fahrenheit!)  When you are on a mountain in Antarctica, it gets really cold!  The average temperatures mainly vary from -10 C to -30 C  The average low is close to freezing.  The average is 0 C (32 F)  The average high is 9 C (48 F)  In the mountain area it mainly averages -20 C (-4 F)

ANTARCTIC EXPLORATION HISTORY BY JOSHUA HASKETT 1773: Captain James Cook and his crew cross the Antarctic Circle 1915: Ernest Shackelton and his crew tries to arrive at the south pole, but never arrive as his ship gets stuck in pack ice. The crew are forced to survive, and are part of the world’s most famed survival story. 1935: Lincoln Ellsworth is the first to successfully fly across the continent. Antarctica is a very unexplored continent. It has had only 300 expeditions.

LANDSCAPE HANNAH HUFF Long ago, Antarctica didn’t use to be ice and snow. There even use to be dinosaurs. Antarctica is the 5 th largest continent of seven continents. In the winter, Antarctica doubles in size due to the sea ice that forms around the coasts. More than 98 percent of Antarctica is ice. This contains about 70 percent of the world’s freshest water.

SEASONS BY. AUSTIN JACKSON  The seasons in Antarctica are the opposite of the Northern hemisphere.  September through February is summer and winter is May through August.

ANTARCTICA HISTORY VICTOR MURILLO  The name Antartica comes Terra Australis which is Antartica’s old name in the dinosaur ages when it was part of a supercontinent.  Antartica got it’s name from a guy named Marinus of Tyre.  When Antartica was part of the supercontinent it was named Gondwana.

THE END Antarctica is a great, icy continent and we hope you learned a lot from this presentation. Have a great day!
