What is the composition of the Moon, and how does it compare to the composition of Earth? Of Mercury?
The composition of the Moon and to compare it with the composition of Earth and Mercury.
Explanation of Solution
Introduction:
Moon is the only natural satellite revolving around Earth and is considered to be geologically dead. Mercury is similar to the Moon in several ways as both lack atmospheres and lacks geological activity.
The average density of the Moon is about
Mercury’s density is higher than that of the Moon as Mercury is largely composed of metals. Mercury consists of a metallic iron-nickel core which amounts to
Conclusion:
Therefore, the comparison between the composition of the Moon with Earth and Mercury is as mentioned above.
