Geologists use the term continent in a different manner from geographers. Asia is the largest and Australia the smallest on 7 continents list. [45] 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. En effet, les avancées technologiques ont permis aux scientifiques d'aller plus loin dans la réflexion et par ce biais de From the late 18th century, some geographers started to regard North America and South America as two parts of the world, making five parts in total.

Exploitation pédagogique. The ideal criterion that each continent is a discrete landmass is commonly relaxed due to historical conventions. The current geologic era is relatively anomalous in that so much of the continental areas are "high and dry"; that is, many parts of the continents that were once below sea level are now elevated well above it due to changes in sea levels and the subsequent uplifting of those continental areas from tectonic activity.[84]. Maps of this time though, still showed North America connected to Asia and showed South America as a separate land.[67].
