The process of transferring heat or other properties through the movement of fluids, such as air or water, often involving rising and falling currents.
Convection is responsible for the warm air rising and cool air sinking in the atmosphere.
Convection → It is formed from "con-" (meaning together) and "vehere" (meaning to carry). The word describes the process of carrying heat or matter together, typically in fluids, through movement.
Think of heat being 'carried together' ('con-') in a fluid, which is what convection means.
