Continental crust and oceanic crust are both types of tectonic plates that make up the Earth's surface, but they have several key differences:
Thickness: Continental crust is generally thicker than oceanic crust, with an average thickness of around 30-50 km compared to around 5-10 km for oceanic crust.
Composition: The average composition of continental crust is generally composed of less dense, granitic rocks, while oceanic crust is mainly composed of denser, basaltic rocks.
Elevation: Continental crust usually occurs at a higher elevation than oceanic crust, as it is less dense and therefore "floats" higher on the Earth's mantle.
