    2. Crust, mantle, and core is structure of earth. lithosphere means the uppermost part of mantle + crust. Asthenosphere means the upper mantle + lower mantle. (rmb that mantle is divided into 3 parts i.e. uppermost, upper and lower :D) Asthenosphere is A LOT THICKER than lithosphere. It is in plastic state while lithosphere is in solid state. D convection current 就係在 asthenosphere ga la~
