Why is it so foggy around the rainforest? It looks like a cloud got stuck in all the leaves. The moisture that the rainforest plants spew out makes a fog. It can 'rain' in the middle of the rainforest even if the skies above are sunny.
Where does all the water come from? Won't it ever run out? The same water has been cycling around the world for millions of years. In every glass of water, some water particles will once have been drunk by a dinosaur--and some water particles will have been urinated into the Nile by an ancient Egyptian.
Yechh! That's gross. Ah, but only the pure water in the urine evaporates from the rivers and oceans, leaving the nasty stuff behind. When you drink, sweat and pee, you join in the great global water cycle.
