Based on the large number of craters, we know that the Moon is not geologically active. The Earth and Moon both get hit by space rocks of various sizes. When a meteorite actually impacts the surface of either body, it may leave a crater. The Earth has had many craters on its surface. However, the Earth's mantle is a vast sea of molten rock. The continental plates move over the mantle, and volcanism brings magma from the mantle out to the surface where it becomes lava. These processes gradually erase craters from the surface. If a body has many craters on its surface, we know that it does not have geological process acting on the surface.

Based on the craters on the moon, it appears it is a main target in an intergalactic shooting gallery. There are thousands and thousands of wandering asteroids in the solar system and because of the moon's location, it takes a good blunt of hits from them. See, asteroids that are small enough to break up in the Earth's thick atmosphere never come into contact with the surface of the Earth. But the moon does not have a thick atmosphere, if any at all. So the asteroids have nothing to break them down, so they collide with the moon, thus creating a crater. This has happened many many times over the moon's long life and is likely to continue happening until one big enough to completely destroy it gives it a whack. And we shall be moon-less!!!

The mountains and rift valleys show that most of its changes were caused by meteorite impacts. Also, the surface has not changed very much at all, indicating there is very little geologic activity. There are no tectonic plates on the moon, so there are no earthquakes to change the landscape. Furthermore, the lack of an atmosphere means that there is no barrier to meteorites, and no wind to blow around the dust that makes up the moon's surface--so the craters that we see now are thousands or millions of years old and have barely changed since the beginning, if at all. Overall, with the exception of meteorite craters, the moon is very similar today to what it was when it first formed.

well i see alot of my answer already posted. it has a solid core so no volcanic activity since there is no weather on the moon all changes are made from outside forces IE meteorites, solar winds. and preserved in that state until another outside force comes along. the makeup of the moon is very comparable to earths composition leading to theories of a significant impact on the earth that created the moon. which also leads to the theory of why earth rotates instead of being in a synchronized orbit around the sun.

to answer a post above there is less impacts then before because slowly all the space debris is gathers up by planets so there is less out there which all started with the big bang.

one last thing the moon moves further from the earth by appox 1/4 of an inch a year i think that measurement is correct either way the moon is moving father from earth as we speak.

If you look at the surface of the moon you'll see a lot of craters. You can even see some of them from Earth without any devices (the ones that form a sort of face) this tells us that
1) the moon has been around for quaite a while
2) a lot o fmeteorites have crashed into it
3) meteorite activity was a lot higher before (we do not observe activity that high now)

It tells us that the first man to the moon was actually shot in Hollywood, not on it's surface...!!!

The moon never had an atmosphere, otherwise the asteroids would have burned up before hitting it.

That it has a history of being hit by asteroids.
