Cumulonimbus

There's a lot more to know about clouds but these are the basics. Mad Scientist has put together a few sites that will put you on cloud nine. You'll find them at the bottom of this article.

Did You Know...?
Clouds fly higher during the day than during the night.
Pink mother-of-pearl clouds can be found very high (about 80,000 ft or 24 kms.) These clouds are very thin and can usually be seen before sunrise or after sunset. The clouds are lit by the Sun, which is below the horizon.
The winds inside cumulonimbus clouds can reach a speed of 124 miles per hour (201 kms) - about as fast as most express trains.
Sunbeams that shine down through clouds are called crepuscular rays.
