How do Clouds form? Type of clouds | Science for Kids?

Clouds are like big groups of tiny water droplets floating high up in the sky.

When warm air rises from Earth, it carries water vapor, which is like invisible steam you see when you boil a pot of water. As this warm air goes higher, it meets cooler air, and the water vapor turns into tiny drops of water or ice crystals, just like how steam becomes fog in your bathroom on a cold day.

How Clouds Look Different

There are many types of clouds, and they look different because of where they form and how big those tiny water droplets get:

  • Cotton candy clouds, called cumulus, puff up like soft pillows, you can see them floating high.
  • Layered clouds, called stratus, cover the sky like a gray blanket, it's like when your room gets foggy from a hot shower.
  • Tall, wispy clouds, called cirrus, look like feathers and are found high in the sky, they’re made of ice crystals!

Each type of cloud is just a group of tiny drops or crystals, but together they make beautiful shapes that change all day long.
