- 2. Equilibrium The balance between the inward pull of gravity and the outward pressure from nuclear fusion that keeps the sun stable.
- 3. The innermost layer of the sun where temperature and pressure are high enough for nuclear fusion to occur.
- 6. The visible "surface" of the sun from which light is emitted.
- 7. The element produced as a result of hydrogen fusion within the sun's core.Core: The innermost layer of the sun where temperature and pressure are high enough for nuclear fusion to occur.Plasma: A state of matter consisting of ionized gas; the sun is primarily composed of this "fourth state of matter."Radiative Zone: The layer of the sun's interior where energy is primarily transported outward by photons.Convective Zone: The outermost layer of the sun's interior where energy is transferred by the physical movement of hot plasma rising and cooler plasma sinking.Photosphere: The visible "surface" of the sun from which light is emitted.Photon: A particle of light that carries energy from the sun's core to space.Gravity: The force that pulls the sun's mass inward, creating the intense pressure needed to trigger fusion.Hydrostatic Equilibrium: The balance between the inward pull of gravity and the outward pressure from nuclear fusion that keeps the sun stable.Chromosphere: The thin, reddish layer of the sun's atmosphere located just above the photosphere.Corona: The outermost layer of the sun's atmosphere, which extends millions of kilometers into space.Mass-Energy Equivalence: The principle (\(E=mc^2\)) explaining how the small amount of mass lost during fusion is converted into a large amount of energy.
- 8. zone The layer of the sun's interior where energy is primarily transported outward by photons.
- 9. fusion The process where hydrogen nuclei combine at extremely high temperatures and pressures to form helium, releasing massive amounts of energy.
- 10. zone The outermost layer of the sun's interior where energy is transferred by the physical movement of hot plasma rising and cooler plasma sinking.
- 12. The force that pulls the sun's mass inward, creating the intense pressure needed to trigger fusion.

- 4. A state of matter consisting of ionized gas; the sun is primarily composed of this "fourth state of matter."
- 5. A particle of light that carries energy from the sun's core to space.
- 7. The lightest and most abundant element in the universe; it serves as the primary fuel for the sun’s fusion process.
- 11. The outermost layer of the sun's atmosphere, which extends millions of kilometers into space.
