Daily Science Fact
 With the exception of the possibility that there may be water ice at the poles of the Moon in craters that are permanently shadowed from the Sun's rays, there is virtually no water on the Moon -not running across the surface, not in the rocks. This eliminates a whole class of rocks found on Earth, the sedimentary rocks, that are formed by deposition or precipitation in water. There are no sandstones or limestones on the Moon!
