By chemically ,
The Earth is composed of the crust, the mantle and the core whereas ,
By mechanically or ( by the state of liquids) ,
The Earth is divided into different spheres , i.e. , the lithosphere, asthenosphere, mesospheric mantle, outer core, and the inner core.( which is based on physical properties )
