The Earth is centrally concentrated. The material that is in the center is much denser than what we find at the surface. This means that the density of our Earth's moon is about 3.3 times that of water which is just slightly greater than that of Earth rocks. What does this imply for the central concentration and composition of the Moon? What does this tell you about the possibility of joint origin of the Moon and Earth?

Hi. The density of surface rocks does not give you too much information. If we assume that the collision theory is true then the lighter material near the surface of Earth should have preferentially been concentrated in the Moon's structure. The Moon would be less dense overall. If we assume joint origin then the materials should be more evenly distributed and the Moon would have a larger iron core. I don't know if either is correct.
