- Materials differentiation inside earth's layers:
Earth layers are differentiated in the different layers of earth layers, on the basis of different properties they have, as the earth is made up of a very fine layers of different elements.

- The outer core,
- The inner core.
- As due to earth's properties it cools down all the materials in such a manner that the denser material sinks to the center, while the less dense floats near to the mantle layer of the earth.
