Okay, so I have this homework and it is in science. This wouldn't be cheating because it isn't in the book and it doesn't say anything about it anywhere else! Here is the question:
Lunar rocks are very old and do not look as if they were eroded by water. Also, no rocks have been found that contain water combined with minerals, as are found on Earth. What can you infer about how long the moon without water?
UHHHH THAT DOESN'T MAKE ANY DOLLARS AND SENSE!!!
PLZ HELP ME! Just so you know, this is about space and the moon. That was a tip! PLZ help! THANKS!
Lotsa Love,

The moon never had water or the lack of athmosphere on the moon made the water that it had to eveporate really quickly (around the time it was created)
The Moon lacks a significant atmosphere, which eliminates erosion due to weather, it does not possess any form of plate tectonics, it has a lower gravity, and because of its small size, it cooled more rapidly. The complex morphology of the lunar surface has been formed by a combination of processes, chief among which are impact cratering, and volcanism. The Moon is a differentiated body, which possesses a crust, mantle and core.
Primary igneous rocks in the lunar highlands compose three distinct groups: the ferroan anorthosite suite, the magnesian suite, and the alkali suite.

Well, if the lunar rocks haven't been eroded w/water, and there isn't any indication that the rocks contain water combined w/minerals, then we can probably infer that there either never has been water, or it's been a long time since there's been water on the Moon. Does this help?

Just think a moment. I know that might be hard, but you can do it if you just take a deep breath. This isn't brain surgery, you know.
If lunar rocks have not been eroded by water, and have no signs of water in the minerals, doesn't it follow that the moon has been without water its entire existence?
So if the moon is 4.5 billion years old, that's how long its been without water.

If the moon rocks the astronauts brought back showed no water attached to any minerals that made up the rocks, then we can tell that there has been no water on the moon since it formed 4.3 billion years ago. That is the age of the oldest rocks brought back from the moon.

If it isn't in the book, then perhaps you should have paid attention in class. There certainly is information on the internet about this. The problem is that you'd probably learn a lot by having to look for it yourself. Sucks, don't it?
