is australia the biggest continent in the world
Continent By convention, "continents are understood to be large, continuous, discrete masses of land, ideally separated by expanses of water."[2] 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.
