Density stratification is the primary physical process responsible for the formation of Earth's layers. As the planet was forming, denser materials (such as iron and nickel) sank to the center to form the inner and outer core, while less dense materials rose to the surface to form the crust. This process is driven by the force of gravity, as more dense materials are pulled towards the center of the planet.
