  1. The outermost layer of the sun is called the:
    1. ionosphere
    2. chromosphere
    3. corona
    4. megasphere
    5. photosphere
  2. The most explosive events to occur on the sun are:
    1. granules
    2. filaments
    3. solar flares
    4. solar winds
    5. sun spots
  3. The sun produces energy by converting:
    1. oxygen to carbon dioxide
    2. oxygen to nitrogen
    3. carbon monoxide to oxygen
    4. hydrogen to helium
    5. helium to hydrogen
  4. Although the Sun appears sharp, we can actually see about ____
  5. kilometers into it.
    1. 10
    2. 200
    3. 10,000
    4. 100,000
  6. The visible surface of the Sun
    1. corona
    2. chromosphere
    3. photosphere
    4. nuclear core
  7. The cooler layer of the Sun where the lines in the Solar
  8. spectrum form
    1. corona
    2. chromosphere
    3. photosphere
    4. nuclear core
  9. Deep in the Sun, energy is transferred by
    1. conduction
    2. convection
    3. radiation
  10. Streams of protons and electrons emitted from the sun produce(s):
    1. quasars
    2. spicules
    3. the solar wind
    4. prominences
    5. granules
  11. During periods of high solar activity, huge cloudlike
  12. structures that appear as great arches extending from the sun are often produced. These solar features are called:
    1. quasars
    2. spicules
    3. the solar wind
    4. prominences
    5. granules
  13. The layer of the sun which radiates most of the light that reaches the earth is called the:
    1. ionosphere
    2. chromosphere
    3. corona
    4. megasphere
    5. photosphere
  14. The layer of the solar atmosphere directly above the photosphere is called the:
    1. ionosphere
    2. solarsphere
    3. corona
    4. megasphere
    5. chromosphere
  15. The source of the sun's energy is:
    1. chemical burning
    2. heat of contraction
    3. nuclear fission
    4. potential energy
    5. nuclear fusion
  16. The most likely cause of the eventual extinction of life on earth:
    1. The Sun becoming a supernova
    2. The Sun becomes a red giant
    3. The Sun becomes a white dwarf
    4. The Sun becomes a Quasar
    5. Gradual heating of the earth as the Sun brightens
