Clouds are high flying fogs. I am not sure how clouds get formed. But the clouds know how to do it, and that is the important thing. Clouds just keep circling the Earth around and around. There is not much else to do.
Rain is saved up in cloud banks.
In some rocks you can find the fossil footprints of fishes. Cyanide is so poisonous that one drop of it on a dog's tongue will kill the strongest man. A blizzard is when it snows sideways. A hurricane is a breeze of a bigly size. A monsoon is a French gentleman.
