Why does continental crust stand higher than oceanic crust? What will be an ideal response?
Continental crust is granitic with an overall density of 2.7 g/cm3, and oceanic crust is made of basalt
and gabbro with a density for 3.0 g/cm3. Continental crust is around 35 km thick, and in mountain
ranges, it's much thicker. Oceanic crust is only 5 to 10 km thick.
