How are clouds formed?
When damp air rises towards colder layers of air, it cools.
The water in the air condenses.
This means that the water transforms from a gas to a solid state.
Tiny, tiny water droplets and ice crystals form
and we see a cloud.
When the air sinks again, it is warmed by the sun’s rays
or it mixes with drier air, and the cloud dissipates.
The water returns to an invisible gas.
