Final answer:
Differentiation is the process of separating materials based on density, creating Earth's core, mantle, and crust.
Explanation:
Differentiation is the process of separating materials within a planet based on density, where denser materials sink to the core while lighter materials float upward. In Earth's case, this led to the formation of layers - the core, mantle, and crust - with iron and nickel in the core and silicate minerals in the mantle and crust.
