You are walking on a beautiful forest path in the rain when you think, "I wonder where all this rain goes?"  That is an excellent question.  Some North American rainforests receive up to 2.5 metres of rain in a year!  You would think that, because of all that rain, the forest floor would always be underwater.  Of course, that is not the case!  What actually happens to that water?

Although much rainwater sinks into the ground or is carried away by streams, trees are excellent water "recyclers".  Trees use some of the water to nourish their cells and some to make food; the rest is passed out the leaves into the atmosphere where it can turn into clouds and rain again.  That repeating movement of water is known as the water cycle.
