  5. Coronal Mass Ejection
  1. a Large explosion on the surface of the sun when hot gas breaks free of the magnetic field
    * emits energy
    *lasts only seconds, unlike longer prominences (but smaller and more violent)
    *can knock out electricity
  2. b Large solar storms that blast out a cloud of a billion solar wind particles
  3. c Total energy radiated by the Sun. NOT BRIGHTNESS!
  4. d Where nuclear fusion takes place

5 True/False questions

  1. Coronal Holes:Hot atmosphere around the Sun

    *Visible only during total solar eclipse, when both the photosphere and the chromosphere are obscured by the Moon.
    *B/C its so hot, must have internal heat source (electromag interaction?)

          

  2. PhotosphereThe visible surface of the Sun. Creates visible light!

          

  3. Convection ZoneTransfers radiation from nuclear fusion outward through RADIATION

          

  4. Sun Spots11 year period during which the # of sunspots rise and fall
    *The high point in the cycle=largest corona

          

  5. The numbers of sunspots and their activity peak about every:Eleven years
