Definitions for "Convection Zone"
The solar layer just below the photosphere, in which plasmas circulate between the Sun's radiation zone and the solar atmosphere, carrying energy outward. ( go to first use in the text)
the region of a star's interior where energy is transported outward using bulk motions of rising hot gas and sinking cool gas. For the Sun, it is the region above the radiative zone.
the outer third layer of the sun. The energy created in the core of the sun is transported through the convection zone similar to boiling water. The gases of the convection zone seem to "bubble" to the top and release the energy
