# Subcontinents
From Wikipedia 
Further information: Indian subcontinent and Arabian Peninsula
Certain parts of continents are recognized as subcontinents, especially the large peninsulas separated from the main continental landmass by geographical features. The most widely recognized example is the Indian subcontinent.[51] The Arabian Peninsula, the Southern Cone of South America, and Alaska in North America might be considered further examples.[51]
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.[52] Greenland, generally reckoned as the world's largest island on the northeastern periphery of the North American Plate, is sometimes referred to as a subcontinent.[53][54] This is a significant departure from the more conventional view of a subcontinent as comprising a very large peninsula on the fringe of a continent.[51]
Where the Americas are viewed as a single continent (America), it is divided into two subcontinents (North America and South America)[55][56][57] or three (with Central America being the third).[58][59] When Eurasia is regarded as a single continent, Europe is treated as a subcontinent.[51]
