It's the change (decrease) in density with heating that produces the currents that we refer to as convection currents.
Conduction, convection, and radiation describe methods of heat transfer. Conduction is heat transfer through direct contact, convection is heat transfer through the movement of fluids or gases, and radiation is heat transfer through electromagnetic waves.
In a natural convection process, hot air rises at a speed of about 1-3 feet per second.
Convection is the process whereby heat is transferred by the mass movement of molecules from one place to another.
Convection is the transfer of heat through the movement of fluids (liquids or gases). This occurs as hot fluids rise and cold fluids sink, creating a continuous flow of heat transfer. Convection is an important process in the Earth's atmosphere, oceans, and interior.
The convection process itself is not a problem; rather, it is a natural mechanism of heat transfer in fluids (liquids and gases). Convection is driven by the transfer of heat through the movement of the fluid.

You don't transfer convection. Rather, convection is a process whereby heat energy is transferred.
In convection less molecules occupy large volume as in air to reduce the density.

convection
The process is called convection. Convection is the transfer of heat through the movement of fluids, such as wind or water, from one place to another.
In this process, heat is transferred by the bodily movement of particles of the medium due to difference in densities of different parts of the medium. convection process is also slow.
