Earth convection definition
WebConvective heat transfer is the transfer of heat between two bodies by currents of moving gas or fluid. In free convection, air or water moves away from the heated body as the warm air or water rises and is replaced by a cooler parcel of air or water. In forced convection, air or water is forcibly moved across the body surface (such as in wind ... WebMar 29, 2024 · The Definition of Convection Convection is a method of thermal energy transfer where the transfer of heat occurs via fluid motion. This fluid motion is caused by the difference in density between hotter regions of the fluid and cooler regions.
