Antarctica wasn't declared a continent until 1840.

The average temperature in Antarctica in summer is 20°F (-6.66°C), while the average temperature in winter is -30°F (-34.44°C). Note: Antarctic winter months are the reverse of those in the Northern Hemisphere.
The coldest temperature ever officially recorded on Earth was -129°F (- 89.2ºC), at Vostok, Antarctica, on July 21, 1983.
The average precipitation in Antarctica is less than two inches (5 centimeters) per year.
The highest wind speeds in Antarctica were clocked at over 200 miles (322 kilometers) per hour.
The highest mountain in Antarctica is the Vinson Massif, which is 16,062 feet (4,897 meters) high.
Ninety-eight percent of Antarctica is ice-covered.
There are no countries in Antarctica. The land is managed under an international treaty signed in 1959.
Antarctica is the world's coldest, windiest, highest, and driest continent. Beneath the ice, some parts of Antarctic are 2,555 meters (8,380 feet) below sea level.
Midnight sun occurs throughout the Antarctic and Arctic at any latitude higher than 67.5° (three-quarters of the way from the Equator to the Poles). It is so intense that in the summer, Antarctica receives more solar energy per day than do lands near the Equator. Sunburn and snow-blindness (from intense glare) are serious risks.
The population of Antarctica varies from 4,000 people in the summer to 1,000 in the winter.
Antarctica is losing ice cover due to global warming, but it is cold enough there that, unlike the Arctic, most of it likely won't melt. Winter ice on the seas may diminish however—a bad thing for penguins.

Polar bears eat seals, but they don't eat penguins. That's because penguins are only found in the Southern Hemisphere, and polar bears live in the Arctic.

if you are in antartica and you are in a plain surrounded by nothing and your collegue is talking to you,then you cannot hear it and even if you reply other personn cannot hear it.

The lowest temprature once recorded in the world was in Vostok Antartica which was -89.2 °C approx!

Vostok, Antarctica is the home of the coldest temperature on Earth at a cool -89 °C (183 K). At the Russian research station the temperature is regularly in the -30 to the -60 °C mark. This chilly weather is due to the exceptionally high speed of the arctic winds. The katabatic or downward type winds that bring the brisk temperature, travel with speeds up to 200 mph (about 90 m/s) from inland toward the coast of the continent. As one moves toward the higher region inland -- that is, toward the true pole -- the temperature drops from its normal -40 °C to -80 °C. The coldest temperatures usually occur during the winter months of around March 22. That is when Antarctica has completed days of darkness. Warmer temperatures, usually still well below freezing, occur during the all day summer months around September 22.

Antarctica also holds the previous record of the lowest temperature on Earth at -88 C. Although still unofficial, Vostok Station may have broken its own record for the coldest temperature on Earth. It has been reported that Vostok reached the temperature of -91 °C during the winter of 1997.

Global warming and Antarctica
Since 1945, the Antarctic Peninsula has experienced a warming of about 4.5?F (2.5?C). The annual melt season has increased by 2 to 3 weeks in just the past 20 years.

The 770 square mile (1,994 km2) Larsen A ice shelf disintegrated suddenly in January 1995.

After 400 years of relative stability, nearly 1,150 square miles (2,978 km2) of the Larson B and Wilkins ice shelves collapsed between March 1998 and March 1999.

Measurements from data recorders in the Southern Ocean waters around Antarctica show a 0.3?F (0.17?C) rise in ocean temperatures between the 1950s and the 1980s.

The permanent ice cover of nine lakes on Signey Island has decreased by about 45% since the 1950s. Average summer air temperature has warmed by 1.8?F (1?C).

The northern section of the Larsen B ice shelf, an area of 1,250 square miles (3,250 km2), disintegrated in a period of 35 days. This was the largest collapse event of the last 30 years, bringing the total loss of ice extent from seven ice shelves to 6,760 square miles (17,500 km2) since 1974. The ice retreat is attributed to the region?s strong warming trend - 4.5?F (2.5?C) in the last 50 years.
