Continent – Wikipedia

Under this scheme, … In geology, a continent is defined by continental crust, which is a platform of metamorphic and igneous rock, largely of granitic composition. Continental crust is less dense and much thicker than oceanic crust, which causes it to “float” higher than oceanic crust on the dense underlying mantle. This explains why the continents form high platforms surrounded by deep …
