convection
The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat
the transfer of heat through a fluid (liquid or gas) caused by molecular motion
(meteorology) the vertical movement of heat or other properties by massive motion within the atmosphere
Convection is the movement of molecules within fluids (i.e. liquids, gases) and rheids. It cannot take place in solids, since neither bulk current flows nor significant diffusion can take place in solids.
