The interior of the moon is layered into a hard, outer crust, a rigid outer mantle, a semi-rigid inner mantle, and a core. The interior of the moon is cooler than the interior of the Earth. Since the moon is so small (and its surface area to volume ratio is also small compared to the Earth), it loses its heat quickly into space. Since the Earth and the moon formed, the moon has cooled down much more than the Earth. Crust: The moon's surface is dry, dusty and rocky. The rocky crust is about 37 miles (60 km) thick on the side of the moon that faces Earth and about 62 miles (100 km) thick on the opposite side of the Moon. Radioactive dating of moon rocks from NASA's Apollo mission dates the formation of the moon from about 4.3 billion years ago (about 60 million years after the formation of the Earth). Moon rocks that have been analyzed by NASA are similar to Earth rocks, but are richer in the elements aluminum and titanium. When the minerals Armalcolite (named for the three astronauts on NASA's Apollo 11: Neil A. ARMstrong, Buzz ALdrin, and Michael COLlins), Tranquillityite, and Pyroxferroite were found on the moon, they were not known on the Earth. At least some of these minerals have since been found on the Earth. Rigid lithospheric mantle: This rocky layer is not hot enough to flow. This hard shell is about 620 miles (1,000 km) thick. Non-rigid mantle: Only the deepest parts of this asthenospheric layer (rock which is less rigid than in a lithosphere but rigid enough to transmit seismic waves) are hot enough to flow. Core: The non-fluid core may be composed of iron-rich rock. The core contains only about 2-4 percent of the Moon's total mass; this core is probably about 225 miles (360 km) in diameter). This small, non-fluid core does not create much of a magnetic field; the moon's magnetic field is about one ten-millionth of the Earth's magnetic field. A compass wouldn't work on the moon, but since the sky is always dark (because there is no atmosphere), you could navigate by looking at the stars.

How are the structure of the Moon and the structure of Earth similar?

The internal structures of the Moon and Earth are similar because of their layers. The Moon has layers that include the crust, mantle, partially melted layer of the core, the liquid outer core, and the solid inner core. The internal structure of the Earth is also divided into layers, there is the Lithosphere (which contains the atmosphere, of which there is none on the Moon), the crust, the upper mantle, the lower mantle, the Asthenosphere, the liquid outer core and the solid inner core.

Are there moon quakes on the moon?

The moon does not have moon quakes; it appears to be 'geologically' dead. The moon's core is smaller in proportion than is earth's core. At one time the moon was volcanically active, but it is no longer. It has cooled sufficiently so that internal energy is no longer sufficient to produce such activity.
