So as I understand, the earth bulged at the equator due to the “centrifugal” forces. I assume that if that is the case, then the average bulk density of “earth” near the equator will be less than that at the poles. Average bulk density as I think would be the say the average bulk density of soil for a 300 ft bore taken at various locations of the equator.
I think if someone modeled earth on these lines, then the age of the earth could be determined from the flattening at the poles and the density of the soil. (Again, I may be wrong)
Will this method also give some indication as to the radial variation of density inside the earth ?
