CONVECTION = Convection is the transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperature. Warm air is less dense than cold air, and so convection currents can form in the presence of a temperature gradient.

$\huge\underline\mathcal\red{♡Answer♡}$

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.
