Why do we have rain?

Rain plays a major role in the hydrologic cycle in which moisture from the oceans evaporates, condenses into clouds, precipitates back to earth, and eventually returns to the ocean via streams and rivers to repeat the cycle again. There is also a small amount of water vapor that respires from plants and evaporates to join other water molecules in condensing into clouds. http://en.wikipedia.org/wiki/Rain Aug 02 06, 7:41 AM

Water from lakes, rivers, ponds, and streams evaporates and forms clouds. In a cloud, the water droplets (cloud droplets, 1/100 the size of a raindrop) condense and stick to each other, eventually becoming too heavy to stay in the cloud and fall down as rain. If the air is moist and warm in a car or building, and cooler outside of it, water droplets from the air inside may form on the windows, the result, condensation. sorry about my sounding like a refrence book, I read them when I'm bored, wierd, I know.
