Assuming I have the mass, radius and moment of inertia of the earth, is it possible to determine the unique density distribution of the earth? The assumtion is the earth is composed of N shells with constant density and thickness.(adsbygoogle = window.adsbygoogle || []).push({});

I think so, because thats how geophysists do itbut im not sure why

edit: all i do know is I=(2/5)*M*r^2 and I= (integral) r^2 dm

but i dont know how to equate that to prove that the earth is denser in the middle.

thanks
