Weather

Why do clouds float?

A cloud is made up of liquid water droplets that come together when the air is heated up by the sun.

When these droplets are heated, they start to rise.

As the droplets rise higher they then start to slowly cool until they reach the saturation point and condense into a cloud.

As long as the cloud and the air it's made of is warmer than the outside air around it, it floats!
