Thickness:Continental crust is much thicker (averaging 35-40 km) than oceanic crust (6-7 km). Density:It is less dense (about 2.7 g/cm³) compared to oceanic crust (2.9-3.0 g/cm³). Composition:Continental crust is made of felsic rocks (granite), while oceanic crust is primarily ba...
Continental lithosphere stands higher than oceanic lithosphere because continental crust is both of greater thickness and lower density than oceanic crust. The extent of subduction of continental crust below the Himalayas is also in dispute. The continental crust was formed through the continental nucleus...
The presence of continental crust is a signature of plate tectonics that distinguishes Earth from other planets. Because continental crust is made of lighter (granitoid) material than (basaltic) oceanic crust and its overall density is therefore less, the lithospheric segments that contain continental ...
The continental crust is made of low-density material (granitoid d ≈ 2.7) while the oceanic crust (basaltic d ≈ 3.0) is denser. Consequently, the presence of continental crust in lithospheric segments confers to them more buoyancy, such that, due to... Author information Authors and Affiliat...

16. h=H(1-a/b)Continental crust sits much higher than oceanic crust because of differences in density. In fact, for many objects with a similar shape and of known height, H, and density, a, floating in a fluid of density, b, the distance, h, that it protrudes above the liquid's...
Much of early Earth was fluid, and the varying elements and materials that composed Earth were differentiated into layers because of their differences in density. Heavier and denser elements like iron and nickel sank deeper into Earth's interior in larger quantities. Whereas lighter elements like ...
Density The difference in density has an impact on isostacy of crust floating on the semi-fluid upper mantle (asthenosphere), withcontinental crust(about 2.7g/cm3) rising or floating aboveoceanic crust(about 3.5 g/cm3). Age Thecontinental crustis older than the oceanic crust. This fact can ...
Continental crust is made up of felsic material (SiO4)-- mainly granite. The density of continental crust is 2.9 g/cm^3. Oceanic crust, while thinner, is made of mafic materials (Fe, Mg)-- mainly basalt. The density of oceanic crust is 3.0g/cm^3. The amount of material has ...
