Answer
The most powerful lifting mechanism is initiated by the heat of the Sun. When the Sun heats the Earth's surface, successive warming of shallow layers in contact with the ground takes place. The buoyancy of this heated air generates thermal up - currents. Down - currents follow as a necessary consequence, to fill the voids left by the up-currents. This process is called convection
The volume of rising warm air increases as the surrounding atmospheric pressure falls, cooling as heat is consumed during expansion. If the rising air is dry or unsaturated it will cool at the dry adiabatic lapse rate, 9.8ºC for every 1 kilometre increase in altitude. Sooner or later, depending on its vapour content, the dew point will be reached and condensation will occur forming convection clouds or cumulus clouds
