A convective flow is the motion of a fluid due to differences in density.
These differences in density commonly occur due to temperature gradients. For example the circulating air flow in a room with a hot radiatior.
convection is produced by the transferring of heat by the the flow of material.
Lack of a flow medium will inhibit conduction and convection.

A convection current, however, this can also occur with gases.
Heat flow is made by conduction, convection or radiation.
