In which region of the sun does energy move through circulating currents of gases?

the convective zone of the sun

Explanation:

In the the convective zone of the sun the energy is carried upwards by the rising hot gas and subsequently it cools and descends, that is to say that the energy is transported mainly by means of convection.

In this area, circular current patterns are formed where the hot plasma rises and the cold plasma descends.
