KINDS OF CLOUDS
There are 3 main kinds of clouds: Cumulus, Stratus, and Cirrus. Cumulus clouds are the fluffy clouds that look like cotton balls. Stratus clouds are layered and often dark and close to the ground. Fog comes from Stratus clouds being very low to the ground. Cirrus clouds are thin and feathery. When you see Cirrus clouds that means the weather is usually nice. These clouds are opposite of Stratus clouds because they are really high up in the sky.
