The Earth’s density increases with depth. If the Earth had the same mass and radius, and  rotated with same angular velocity, but it had a density that decreased with depth instead -- how would its rotational kinetic energy compare to the actual value? To be clear: The actual Earth is densest at the core; the one you are being asked about would be densest at the crust. a.) It would be the same as the actual value. b.) It would be less than the actual value. c.) It would be greater than the actual value. d.) More information is needed to find the answer. Please choose the correct answer.
