What is the primary composition of the continental crust?

The primary composition of the continental crust is granitic rock, which is characterized by its light color, coarse texture, and relatively low density compared to other types of crust. Granitic rocks primarily consist of quartz and feldspar, with lesser amounts of mica and other minerals. This composition gives the continental crust its elevated position relative to oceanic crust, which is predominantly composed of basalt, a denser, darker volcanic rock.

The thickness of the continental crust can vary significantly, but it generally is thicker than the oceanic crust, contributing to the stability and geological features of continents. Granitic rocks are also commonly associated with the tectonic processes that form mountain ranges and other landforms, further emphasizing their importance in the geological framework of continental areas.
