Final answer:
The Moon's density is 3.3 g/cm³, which is considered low, especially when compared to Earth's average density of about 5.5 g/cm³.
Step-by-step explanation:
The Moon's overall density is 3.3 g/cm3. This is considered a low density when compared to Earth's average density. The lower density suggests that the Moon is composed largely of silicate rock and is depleted in iron and other metals compared to Earth. In terms of density, Earth is far denser, with an average density of about 5.5 g/cm3, indicating a composition that includes a significant amount of metals, which contribute to a higher overall density. The comparison of densities between celestial bodies like Earth and the Moon offers insight into their compositions and formations.
