Expanding air cools. Work has to be done on the molecules for them to spread apart. A positive amount of work means the kinetic energy in the system decreases. As the air rises, the pressure decreases, causing the molecules to loose energy, which is what we perceive as the cooling of the air.
The process of warm air rising and cool air sinking is called convection current The process of warm air rising and cool air sinking is called convection current
Condensation
The process of warm rising and cool air sinking is called convection. Convection is the concerted, collective movement of groups or aggregates of molecules within fluids and rheids, either through advection or through diffusion or as a combination of both of them.
Cool air moving to take the place of warm air rising is also known as Wind
A mass of cold air replacing warm air is called a 'cold front', - this usually causes rain.

the rising and warming of cool air
I believe this is what causes wind and air currents.

Yes warm air and low pressure can cause rising air.
