How does rain form?
Warm air causes war on the ground, in lakes and the sea, and from vegetation to evaporate.
Warm air and water vapour is forced to rise.
As it rides, it cools.
Further cooling causes condensation were water vapour is turned back into minute water droplets, which are visible a clouds.
If cooling continues, increasing condensation will form rain (or snow if temperatures are below 0 degrees Celsius.
