The layer defined by its chemical composition is the mantle. While the inner core and outer core are defined more by their physical state (solid and liquid, respectively), the mantle is distinguished by its mineral composition. The lithosphere is a rigid layer formed from the crust and the uppermost part of the mantle, but it involves mechanical properties rather than purely chemical composition.
