Heat transfer is accomplished often on earth and other planets and the stars by convection, but there are other ways of heat transfer. Heat is transferred by radiation as the sun to earth, and sensible heat is transferred by conduction, simply being in contact.
Convection heat transfer is the transfer of heat by the movement of a fluid.
Convection is "the transfer of heat through the motion of molecules in a fluid."
The transfer of heat by fluid is convection.
