1. Core: This is the innermost layer where nuclear fusion takes place. It makes up about 2% of the Sun's volume, but contains 50% of its mass.
2. Radiative Zone: This layer surrounds the core and energy is transported outward by radiation. This zone is about 70% of the Sun's volume.
3. Convective Zone: This is the outermost layer where energy is transported outward by convection, similar to how water boils. This zone makes up the remaining 30% of the Sun's volume.
It's important to note that these are just the three major layers. There are other layers, such as the photosphere, chromosphere, and corona, which are located above the convective zone and form the outer atmosphere of the Sun.
