How do clouds...work

When you're flying in a plane or looking up at the sky, of course you see clouds. But if you think or focus on the clouds, you will probably ask yourself the question above. I'm confused about clouds and I don't see why they... exsit.
1.) why do we have clouds?
2.) how do clouds float?
3.) how do clouds feel?
4.) how do clouds work?

1. clouds are "pockets" of evaporated water that pool up in the sky, and when enough water clumps together it gets too heavy to stay afloat and falls back down as rain

2. its water vapor that is lighter than air until whats mentioned above happens

3. wet

4. see 1

Clouds occur when air rises and cools enough that the water vapor in the air begins to condense out. They float because clouds are composed of very tiny water droplets or very small ice crystals, which are easily held up there by even slight amounts of rising air. Fog is a cloud that is in contact with the surface, so if you have ever been outside on a foggy day, you know how they feel. Clouds don't really "work", but processes within them allow rain and snow to fall from them, as well as hail sometimes.
