Differentiation

Explanation:

Planet differentiation can be defined as the process of chemically separating the various constituents of a planetary body by outgassing of volatilities and partial melting into different distinct or distinguished compositional layers.

Differentiation explains the arrangement of the inner planets' composition into different chemical layers. During the differentiation of the inner planets composition, less-dense liquids erupts from the melt in the direction of the planets' surface and then crystallizes to form a crust, which typically result in the depletion of elements such as Aluminum and Silicon from the mantle.

The various chemical layers of the planet Earth are the mantle, crust, and core (inner and outer).
