Main Body
1The gravitational force is exerted by earth's mass on top layers. 2) Buoyant force is exerted by the molten magma and liquid core that is constant in state of convection. 3) It leads to stratification in interior of layers with denser materials setting down and lighter materials coming up.
The theory explains how earth's crust maintains its shape and equilibrium. Role in shaping Earth's major landforms
