Order of the Sun's internal structure from the center outward.

• A. Core, Convective Zone, Radiative Zone, Photosphere, Chromosphere, Corona
• B. Photosphere, Chromosphere, Corona, Core, Radiative Zone, Convective Zone
• C. Core, Radiative Zone, Convective Zone, Photosphere, Chromosphere, Corona
• D. Core, Radiative Zone, Convective Zone, Photosphere, Chromosphere, Corona

Answer: (D)

Energy generated in the Sun’s core must travel outward through successive zones before it can escape. In the radiative zone, energy moves mainly by photons diffusing outward rather than by bulk movement. Beyond that, the convective zone carries energy to the surface through the rising and sinking motions of hot plasma. The visible surface we detect is the photosphere, the layer from which most light escapes into space. Above it lie the chromosphere and the corona, the outer atmospheric layers that glow in specific wavelengths and during eclipses. So the sequence from inside to outside is core, radiative zone, convective zone, photosphere, chromosphere, corona.
