Here's why:
* Radiation Zone: This is the inner layer where energy is transported outward through the absorption and re-emission of photons.
* Convection Zone: This is the layer above the radiation zone. Here, the energy is transported by the movement of hot gas (plasma). This hot plasma rises, cools, and sinks in a continuous cycle, much like boiling water.
So, the convection zone acts as a "blanket" surrounding the radiation zone, carrying the energy generated in the core further out towards the Sun's surface.
