Here's why the Moon's density is lower:
* Composition: The Moon is primarily composed of rock, with a smaller amount of iron. Earth, on the other hand, has a larger iron core, which contributes to its higher density.
* Internal Structure: The Moon's internal structure is less dense than Earth's. While both have a core, the Moon's core is much smaller and less dense.
The Moon's density provides valuable information about its composition and internal structure, helping us understand its formation and evolution.
