    By convention, "continents are understood to be large, continuous, discrete masses of land, ideally separated by expanses of water." In modern schemes with five or more recognised continents, at least one pair of continents is joined by land in some way. The criterion "large" leads to arbitrary classification: Greenland, with a surface area of 2,166,086 square kilometres (836,330 sq mi) is ...
