9.1 - Understand the Moon’s major internal divisions in comparison with those of the Earth

The Moon has similar divisions to Earth. The most striking difference is that the core is much smaller, around 20% of the size of the satellite compared to the much larger planet.
Although the Moon lacks Earth's tectonic plates and volcanism, equipment left by the Apollo missions detected moonquakes from within the mantle of the Moon.
