Clouds

weather · water cycle · sky

Made of tiny droplets. Clouds aren't solid, they're actually billions of microscopic water droplets or ice crystals floating together in the air, kind of like an invisible mist that became visible.

Water vapor rising up. Clouds form when warm air rises high into the sky, cools down, and the water vapor in it condenses into liquid droplets. This happens because cold air can't hold as much moisture as warm air.

Ice or water. Depending on how cold it is way up in the clouds, they can be made of water droplets, ice crystals, or sometimes both mixed together.

Temperature matters most. A cloud forms when the air cools to a special temperature called the dew point, that's when water vapor decides to turn into visible droplets instead of staying invisible.

Found everywhere on Earth. Clouds aren't just over oceans, they float above mountains, deserts, forests, and cities wherever the conditions are right for water to condense in the atmosphere.
