Why is Antarctica called White Continent?
The entire continent of Antarctica is covered with a vast ice sheet. Due to this thick ice cover, there is no vegetation or settlement and hence it looks like a white landscape. Thus, Antarctica is called the White Continent.
Describe the climate conditions of Antarctica.
Climatic conditions of Antarctica:
State the main purpose of the Antarctica Treaty.
The Antarctica Treaty aims:
Why is the climate of Antarctica not suitable for vegetation and cultivation?
The climate of Antarctica is not suitable for vegetation and cultivation because:
Why is continent of Antarctica known as the continent of science?
The continent of Antarctica is known as the continent of science because:
State the future prospects of the continent of Antarctica.
Antarctica is currently safeguarded against mineral exploitation and conflict by the Antarctica Treaty. It will continue to provide ample scope of research in the near future.
However, it is believed to contain valuable mineral resources like coal, oil, gold, and silver. As energy and mineral reserves decline and tourism in Antarctica grows, there will likely be greater pressure to exploit its natural resources on both land and in the ocean in the future.
Describe the location and extent of Antarctica.
Antarctica is world’s southernmost continent, containing the geographic South Pole. It is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle and is surrounded by the Southern Ocean. Its area is approximately 14,200,000 sq. km. It is covered by Permafrost (permanently frozen ground).
Describe the physical features of the continent of Antarctica.

Write a short note on the discovery of Antarctica.
In 1773, James Cook crossed the latitude of 67°15' S along the Antarctica circle for the first time. He only discovered nearby islands. In 1820, the very first to have sighted Antarctica was Russian expedition led by Fabian Gottlieb von Bellingshausen and Mikhail Lazarev. The first Norwegian expedition to Antarctica was led by Captain Carl Anton Larsen in 1892. During the expedition, he was first to discover fossils in Antarctica. Finally, a Norwegian explorer, Roald Amundsen with his team reached the south pole on December 14, 1911.
Why is Antarctica uninhabitable for human beings.
Antarctica's freezing climate and barren glacial coasts with not a drop of fresh water to drink, isolated from the world, makes it impossible for normal life to survive. Therefore, Antarctica is uninhabitable for human beings.
