Convective Zone

The Sun is made up of different layers. From its center outward, the Sun’s lay­ers include the core, the convective zone, the radiative zone, the photosphere, the chromosphere, and the corona. The convective zone extends from just below the photosphere to the radiative zone. In this region convection currents transport the Sun’s energy to the surface.

In the convective zone, rising and falling currents carry heat from the radiative zone to the surface. This nonstop churning is similar to what happens when you boil water on a stove.
