==== Water ====
Water provides the oceans, lakes, rain and all other forms of moisture. Water doesn't fluctuate very rapidly, but its changes are sometimes pronounced, bringing dry days and rain, or drought and floods. Areas with too little water are simply dry. Areas with too much water tend to have a lot of lakes and heavy rains. Even areas underwater can lack water, even if that's hard to put into words. Such areas would be similar to areas that lack air aboveground, but are overall pretty rare. Water vortices tend to form in the deep ocean rifts.
