This happens via a course of known as convection. As photo voltaic radiation heats the bottom and the air instantly above it, the nice and cozy air turns into lighter and the move of air carries this heat air upward. Because the air rises, the temperature decreases and so does the quantity of water vapor that the air can maintain. This vapor quickly condenses and shortly clouds — composed of numerous billions of tiny water droplets or ice crystals — consequence. These droplets are exceedingly small, averaging about 10 microns in diameter (a micron is one-millionth of a meter; ice crystals are a lot bigger however much less concentrated). Just about all forms of clouds and precipitation are attributable to rising air.

Alternatively, as air sinks, its temperature rises and its capability for holding vapor will increase. Then any cloud droplets are likely to evaporate and the cloud itself disappears; evaporation modifications moisture again from liquid into fuel.
