as air cools, the space it occupies becomes less. this result in an increas density
It decreases. As air cools, mist, then clouds, then rain / snow forms... as the moisture is displaced.
It gets colder. And the energy increases so the particles move further apart.
When moist air rises this process is called evaporation.after this most air have rised it condense then rain falls.
Wind is blowing air up over the mountain. Going from about 1,000 feet at the base to 7,000 feet at the top, the temperature changes as the air goes over the mountain.
When water vapor condenses around dust particles a cloud is formed
As air cools, the space it occupies becomes less. This results in an increase in density.
It expands and cools
it cools down
it goes down
Tornados
pressure decreses
It cools, and when it is compressed, it warms
it grows testicles
It condenses and becomes liquid water.
It cools and condenses
it condenses on the ground to make dew
It condenses and it becomes liquid
