Can you tell me about the different types of clouds?

The different types of clouds include cirrus, cumulus, stratus, and nimbostratus. Cirrus clouds are thin, wispy clouds that look like feathers or spider webs. Cumulus clouds are puffy, white, fluffy clouds that often form in groups. Stratus clouds are gray or even black clouds that usually cover a large area. Nimbostratus clouds are dark, low-lying clouds that can block out the sun.
