<P> The structure of Earth can be defined in two ways : by mechanical properties such as rheology , or chemically . Mechanically , it can be divided into lithosphere , asthenosphere , mesospheric mantle , outer core , and the inner core . Chemically , Earth can be divided into the crust , upper mantle , lower mantle , outer core , and inner core . The geologic component layers of Earth are at the following depths below the surface : </P>
