Convection is a process of heat transfer by the movement of fluids (gas or liquid) between regions of various temperatures. If convection occurs naturally it is called natural convection or free convection. If convection is forced to occur, say, if fluid is circulated using a pump or a fan, it is called forced convection. See more Convection currents are generated by the differences in densities of the fluid that occur due to temperature gradients.
