Asia constitutes one-third of Earth’s total land area, making it the larg est of the seven
continents. With about 3.7 billion inhabitants, the continent contains about three -fifths of
the world's population. Asia contains some of the world’s most spectacular natural
features, including high mountain ranges, vast plateaus, majestic river basins, and lakes
and inland seas.

Antarctica is the Earth’s southernmost, coldest, windiest, highest, most remote, and most
recently discovered continent which surrounds the South Pole. The last continent to be
discovered, Antarctica remained hidden behind barriers of fog, storm, and sea ice until it
was first sighted in the early 19th century. Because of the e xtreme cold and the lack of
native peoples, forests, land animals, and obvious natural resources, the continent
remained largely neglected for decades after discovery.

Australia remained relatively unknown to most of the outside world until it was
developed as a group of British colonies during the 19th century. In 1901, the colonies
federated to form a unified independent nation, the Commonwealth of Australia.
Australia lacks mountains of great height; it is one of the world’s flattest landmasses. The average
elevation is about 300 m. The interior is mostly a series of great plains or low plateaus, which are
generally higher in the northeast. Low-lying coastal plains, averaging about 65 km in width,
border the continent. In the east, southeast, and southwest, these plains are the most densely
populated areas of Australia.
D
North America, third largest of the seven continents, includes Canada, the 2nd largest country in
area in the world, the United States (3rd largest), and Mexico (14th largest). With more than 405
million inhabitants estimate, North America is the 4th most populous continent. Together with
Central America, the West Indies, and South America, North America makes up the Western
Hemisphere of Earth. The lowest point in the western hemisphere, 86 m below sea level, is
located in Death Valley, California.

The second smallest continent (Australia is the smallest), Europe has an area of 10,355,000 sq km,
but it has the third largest population of all the continents. Europe is a highly fragmented landmass
consisting of a number of large peninsulas, such as the Scandinavian, Iberian, and Italian, as well
