Liquid water cannot persist at the moon's surface, and water vapor is decomposed by sunlight, with hydrogen quickly lost to outer space. However, scientists have since the 1960s conjectured that water ice could survive in cold, permanently shadowed craters at the Moon's poles.
hope I helped :-)
Overpopulation means more people. The more people there are, the more resources needed to stupport the overpopulation. The more resources that are used the more of a deterioration of our ecosystem therefor causing global warming.
A permeable rock breaks down quicker than a rock that is not so permeable because there is less space for anything (i.e. water) to get in the not so permeable rock in order to widen the holes and ultimately break the rock. On the other hand, a permeable rock is full of holes and will break down because of the many holes available to widen.
