Also it rings like a bell.

While the average density (g/mL is a calculation of
density, not specific gravity. Mass is a property that exists independent of gravity, and mass per volume is a derived unit) of Earth is 5.5 g/mL, and the average density of the moon is 3.3 g/mL, these numbers include the molten cores and mantles of both bodies, which is relatively much larger for Earth and skews its overall average density higher. The average density of Earth's continental crusts, which are slightly less dense than oceanic crust, is 2.67 g/mL, while the average density of the Moon's crust is 2.55 g/mL.
