The continental crust is made of granitic rocks, which have even more silicon and aluminum than the basaltic oceanic crust; they also have more oxygen thanks to the atmosphere. Granitic rocks are even less dense than basalt. In terms of minerals, granite has even more feldspar, less amphibole than basalt and almost no pyroxene or olivine, plus it has abundant quartz. In geologist's shorthand, continental crust is felsic.

According to Science Daily, the types of rock that make up the continental crust include metamorphic, sedimentary and granitic. These rocks form continents and shallow sea beds, which are called continental shelves. The continental crust floats above the Earthâs mantle, as it is made up of a less dense material. The continental crust is also less dense than the oceanic crust, which is primarily made of basalt. However, the continental crust is up to 40 kilometers thicker than the oceanic crust, which is 7 to 10 kilometers thick. Around 40 percent of Earthâs surface is underlain by the continental crust.
