The crust has two and sometimes three sublayers: the maria where applicable (up to 5 km deep) 5 layer of rock fragmented by repeated impacts (up to 25 km deep and layer of unfractured rock (below 25 km) .Below the crust lies the mantle. The upper mantle solid, while the lower mantle partially molten. Moonquakes occur near the base of the upper mantle. The mantle S composed of minerals such as pyroxene and olivine as well as iron and magnesium. It is possible that the molten lower mantle extends a ...
