In many of these cases, the "subcontinents" concerned are on different tectonic plates from the rest of the continent, providing a geological justification for the terminology. [64] Greenland , generally considered the world's largest island on the northeastern periphery of the North American Plate , is sometimes referred to as a subcontinent.

At their nearest points, Alaska and Russia are separated by only 4 kilometres (2.5 miles).

[1] [2] [3] However, some geologists use a different definition, "a grouping of formerly dispersed continents", which leaves room for interpretation and is easier to apply to Precambrian times. [4] To separate supercontinents from other groupings, a limit has been proposed in which a continent must include at least about 75% of the continental ...
