is australia the biggest continent in the world
By convention, ``continents are understood to be large, continuous, discrete masses of land, ideally separated by expanses of water.'' Several of the seven conventionally recognized continents are not discrete landmasses separated completely by water. The criterion ``large'' leads to arbitrary classification: Greenland, with a surface area of 2,166,086 square kilometres (836,330 sq mi) is considered the world's largest island, while Australia, at 7,617,930 square kilometres (2,941,300 sq mi) is deemed the smallest continent.
