Question

Quizplus · Accepted Answer

Convection is the transfer of heat energy through the movement of fluids (gases or liquids) caused by temperature differences. In the context of wildfire combustion, convection occurs as the heated gases rise and the cooler, denser air sinks, creating circulation and carrying heat away from the fire.
