1. Core: The very center of the Sun. This is where nuclear fusion takes place, converting hydrogen into helium and releasing immense energy.
2. Radiative Zone: Surrounding the core, this region is where energy travels outwards through a process called radiative diffusion. It takes millions of years for photons to travel through this zone.
3. Convective Zone: Above the radiative zone, here energy is transported upwards by convection currents, similar to boiling water. Hot plasma rises, cools, and sinks back down.
4. Photosphere: This is the visible surface of the Sun. The light we see comes from this layer. Sunspots and granulation are features found in the photosphere.
5. Chromosphere: A thin layer of gas above the photosphere. This layer is responsible for the red color seen during solar eclipses.
6. Transition Region: A thin, rapidly changing layer between the chromosphere and the corona.
7. Corona: The outermost layer of the Sun's atmosphere. It is a very hot, thin plasma extending millions of kilometers into space. The corona is responsible for the solar wind.
