You know the water cycle from grade school: water evaporates from the oceans and rivers, condenses into clouds, falls to the ground as precipitation, and runs off into the oceans and rivers to start the process again. Except—it's a bit more complicated than that. Not all of the water makes it all the way around the cycle.
