Why are there clouds?
Fascinating! Is there anything else interesting about clouds that you can tell me?
Well, one interesting fact about clouds is that they can come in many different shapes and sizes, from wispy cirrus clouds to towering cumulonimbus clouds. Some clouds even have unique features like rolls or waves. Another interesting fact is that clouds can also produce light phenomena like rainbows and halos under certain conditions.
