Cumulus clouds look like fluffy tufts of cotton floating in the sky. Sometimes they might take the shape of a dragon, a turtle or some other creature. Cumulonimbus clouds are large, flat clouds that spread across the sky. One end of the cloud might be shaped like an anvil.
Clouds found in the low altitude range are indicated by the prefix âstratoâ or by the suffix âstratus.â Their bases are below 2,000 meters (6500 feet) in altitude, and except in cold weather when they can contain ice and snow, they are composed of water droplets. Three types of low altitude clouds are stratus, stratocumulus and nimbostratus. Stratus clouds are gray clouds that often cover the entire sky.
