There are three basic kinds of clouds. Cirrus clouds are thin, feathery clouds. They are high in the sky. They are so high that they are made up of the ice particles. They are generally white or whitish in color.
Cumulus clouds look like puffs of cotton piled in a heap.
They are commonly known as fair-weathered clouds. They are usually nearer the earth than cirrus clouds. Stratus clouds are low, flat clouds. They are often dark and bring rain. Altostratus clouds are higher than stratus clouds.
