Read and find out about the ups and downpours of the water cycle! With colorful illustrations and engaging text, Down Comes the Rain is a fascinating look into the stages of the water cycle. After rain comes down, the sun comes out and dries the puddles. But the water isn't gone. The heat from the sun has turned it into water vapor--it has evaporated. Eventually, this moisture in the air condenses to form new clouds. Soon the rain will fall again.
