8th Grade Ch. 3 Sec. 2 The Sun

  1. 1. Ch. 3 Sec. 2
  2. 2. <ul><li>The sun’s gravity is the most powerful force in the solar system because the sun’s mass is so large . </li></ul><ul><li>99.8 % of the mass of the solar system is in the sun. </li></ul>
  3. 3. Sun’s interior core radiation zone convection zone
  4. 4. core <ul><li>center of Sun </li></ul><ul><li>nuclear fusion </li></ul><ul><li>hydrogen atoms  helium atoms </li></ul><ul><li>occurs only under conditions of extremely high temp. (15 million o C) & pressure </li></ul><ul><li>makes sun’s energy </li></ul>
  5. 5. radiation zone <ul><li>middle layer of sun’s interior </li></ul><ul><li>region of very tightly packed gas </li></ul><ul><li>energy transferred by electromagnetic radiation </li></ul>
  6. 6. convection zone <ul><li>outermost layer of sun’s interior </li></ul><ul><li>hot gases rise & cooler gases sink </li></ul>
  7. 7. layers of sun’s atmosphere 1. photo sphere 2. chro m osphere 3. corona <ul><li>inner layer </li></ul><ul><li>image you see </li></ul><ul><li>in photo graph </li></ul><ul><li>m iddle layer </li></ul><ul><li>reddish glow </li></ul><ul><li>outer layer </li></ul><ul><li>visible during </li></ul><ul><li>total solar eclipse </li></ul>sends out solar wind
  8. 8. corona
  9. 9. solar wind <ul><li>stream of electrically charged particles </li></ul>
  10. 10. features on Sun sunspots prominences solar flares dark areas on sun that are cooler than gases around them loops of gas that link sunspot regions explosions that occur when sunspots connect
  11. 11. # of sunspots varies over a 10-11 year cycle
  12. 12. prominences
  13. 13. solar flares <ul><li>increase solar wind </li></ul><ul><li>cause auroras </li></ul>
  14. 14. ghost wispy witch green ghost The Ring eerie spirit SPOOKY AURORAS
  15. 15. NASA eClips-Our Sun
  16. 16. Edible cookie <ul><li>Arched Twizzler = prominence </li></ul><ul><li>Mini chocolate chips = sunspots </li></ul><ul><li>Sprinkles = photosphere </li></ul><ul><li>Frosting = convection zone </li></ul><ul><li>Cookie = radiation zone </li></ul><ul><li>Center of the cookie = core </li></ul><ul><li>Straight Twizzler = solar flare </li></ul>Song to remember layers
