Question

Can you explain what happens when a cloud forms?

Answer 1

Clouds form as air warms up near the Earth's surface and rises. It is heated by sunlight and the ground heats the air just above it. That warmed air starts to rise because when warm it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense.

Answer 2

The Short Answer: Clouds are created when water vapor, an invisible gas, turns into liquid water droplets. These water droplets form on tiny particles, like dust, that are floating in the air. ... These energetic molecules then escape from the liquid water in the form of gas.
