  1. 2. Equilibrium The balance between the inward pull of gravity and the outward pressure from nuclear fusion that keeps the sun stable.
  2. 3. The innermost layer of the sun where temperature and pressure are high enough for nuclear fusion to occur.
  3. 6. The visible "surface" of the sun from which light is emitted.
  4. 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.
  5. 8. zone The layer of the sun's interior where energy is primarily transported outward by photons.
  6. 9. fusion The process where hydrogen nuclei combine at extremely high temperatures and pressures to form helium, releasing massive amounts of energy.
  7. 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.
  8. 12. The force that pulls the sun's mass inward, creating the intense pressure needed to trigger fusion.

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