The continental crust covers nearly a third of the Earth’s surface. It is buoyant—being less dense than the crust under the surrounding oceans—and is compositionally evolved, dominating the Earth’s budget for those elements that preferentially partit

The type of crust found under the continents is continental crust, also known as sial (rich in silicates (SiO₂ ) and aluminum (Al)) due to its composition of silicates and aluminum. This type of crust differs significantly from the oceanic crust that lies beneath the oceans. Continental ...
Earth is composed of four layers: the crust, mantle, outer core, and inner core, with the crust being where we reside and the inner core being made of solid iron. The movement of tectonic plates on the crust leads to the constant change in the layout of Earth's continents and oceans....
