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
Region of a star's interior, lying just below the surface, where the material of the star is in constant convective motion. This region extends into the solar interior to a depth of about 20,000km.
A layer in a star in which convection currents are the main mechanism by which energy is transported outward. In the Sun, a convection zone extends from just below the photosphere to about seventy percent of the solar radius. more
That region below a star's surface where matter physically upwells, thus transporting energy mechanically.
The convection zone is the outermost layer of the Sun's interior. Energy is transferred there in convection currents, rather than energetic photons. Once hot gas convects up to the photosphere, it emits photons into space, cools, and settles back into the Sun.
