It amounts to less than half of 1 percent of the planet's total mass but plays a vital role in most of Earth's natural cycles.
1 The crust is about 0.5 % of the earthâs total mass. 2  The crust is made up of silicate rocks such as granite and basalt. 3  The continental crust is much thicker than the oceanic crust as shown here in the diagram of the earth's crust. Continental crust (continental cratons) - Where there are continents the crust is about 30 to 50 km thick. 2  It is made up of igneous, metamorphic, and sedimentary rocks. 3  The continental crust is less dense than the oceanic crust.
