NCERT Notes: Structure Of The Earth [Geography Notes For UPSC]
The crust is the outermost solid part of the earth. It is fragile. The thickness of the crust varies under the oceanic and continental areas. Oceanic crust is thinner as compared to the continental crust. The continental crust is thicker in the areas of major mountain systems. The crust is made up of heavier rocks having a density of 3 g/cm3.
