These plates are made of rock, but the rock is, in general, lightweight compared with the denser, fluid layer underneath. This allows the plates to "float" on top of the denser material.

Compositional Stratification in the Deep Mantle

Because of numerical diffusion, our convection model overestimates the rate at which material in the undepleted layer is entrained by plumes; thus, the rate of entrainment and mixing between layers that we calculate is an upper bound. Even with this small artificial diffusivity, the layers in our ca ...

History of geology
The history of geology is concerned with the development of the natural science of geology. Geology is the scientific study of the origin, history, and structure of the Earth. Throughout the ages geology provides essential theories and data that shape how society conceptualizes the Earth.
