1. Describe the most common type of fusion
  in the sun.
 Please define the following vocab:
   Radiative zone
   Convective zone
   Photosphere

1.   Describe the most common type of
     fusion in the sun.

Answer: he fusion of hydrogen into helium
                  Vocab
 Radiative zone: region surrounding the core
  of the sun in which energy is transferred in the
  form of electromagnetic waves.
 Convective zone: the region of the sun’s
  radiative zone in which moving gases transfer
  energy.
 Photosphere : the innermost layer of the solar
  atmosphere; the light sphere

 Wed October 7 and Thur October 8, 2009
 2. How does energy transfer in the
  radiative zone differ from the transfer of
  energy in the convective zone?
 Please define the following vocab:
     Chromosphere
     Corona
     Solar wind
               Warm-up
 2. How does energy transfer in the
  radiative zone differ from the transfer of
  energy in the convective zone?
 Radiation is the transfer of energy by
  electromagnetic waves. Convection is the
  transfer of energy by moving liquids or
  gases.
                 Vocab
 Chromosphere: a thin layer of the sun’s
  atmosphere that lies above the photosphere
  and flows with a reddish light; color sphere
 Corona: the outermost layer of the sun’s
  atmosphere
 Solar wind: electrically charges atomic
  particles that stream out into space through
  holes in the sun’s corona

3. Why are sunspots cooler than the
  surrounding area?
Please define today’s vocab:
 Sunspots
 Sunspot cycle
 Prominence
               Warm up
3. Why are sunspots cooler than the
  surrounding area?
Answer: Because magnetic fields slow down
  convection, less heat is transferred from
  the core to the photosphere.
                 Vocab
 Sunspots: cool dark area of gas within the
  photosphere, caused by powerful
  magnetic fields.
 Sunspot cycle: periodic variation in the
  number of sunspots that occurs
  approximately every 11 years.
 Prominence: A cloud of glowing gases that
  arch high above the sun’s surface.

 4. How are prominences different from
  solar flares?

   Please define today’s vocab:
     Solar Flare
     Auroras
                  Vocab
 Solar Flare- Sudden, violent eruption of
  electrically charged atomic particles from
  the sun’s surface.
 Auroras- Sheets of colored light produced
  by a magnetic storm in the earth’s upper
  atmosphere

   5. What two forces caused the solar nebula to
    develop into the sun?

   Please define today’s vocab:
       Solar system
       Planets
       Nebular theory
       Solar nebula
               Warm-up
5. What two forces caused the solar nebula
  to develop into the sun?

Answer: Heat from collisions and pressure
 from the force of gravity.
                 Vocab
 Solar system: the sun and the bodies that
  revolve around it.
 Planets: any one of the eight major bodies
  that orbit our sun.
 Nebular theory: the theory that the sun and
  the planets condensed out of a spinning cloud
  of gas and dust
 Solar nebula cloud of dust and gas that
  developed into the solar system.
