Which is the world’s smallest continent?
A.Africa
B.South America
C.Europe
D.Australia

Hint:Large land masses are known as continents. There are seven continents which are defined by convention rather than any specific criterion. These seven continents, ordered from largest in area to smallest, are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia.

Complete answer:
The continent is a country by itself. “Down Under” is another name of this island. The continent comprises the island of Tasmania and numerous smaller islands like Kangaroo Island.

In the world, there are seven continents and Asia is the biggest, and Australia is the smallest by land mass at almost a fifth of the size of Asia, but Europe is not far behind, as Australia is just over a million square miles larger than Australia. Australia's measurement is just short of three million square miles, but this encompasses both Australia's main island continent and the neighbouring islands, which are collectively referred to as Oceania.

The continent of Australia is the world's smallest continent in terms of land area. In total, it occupies 7,692,024 square kilometres (2,967,909 square miles), which is somewhat less than both Brazil and the contiguous United States. However, this number includes the tiny island nations that surround it in the area of the world's Pacific Island.

Australia is known for its varied wildlife and biodiversity. The continent has innumerable flora and fauna species which cannot be found anywhere else. A short distance off the north-east coast of Australia lies the Great Barrier Reef, the world's largest coral reef.

Hence, the correct answer is option (A).

Note:As it is surrounded by water, Australia is an island, but it is still large enough to be called a continent, making Australia the world's largest island, but practically, as the island nation is essentially a continent, many consider Greenland the world's largest.
