  5. What's weird about the temperature of the Sun as you move outward?
  1. a The measurement of average kinetic energy in molecules. NOT HEAT!
  2. b Info of the Sun's interior
  3. c The core is super hot, but it gets cooler until you reach the transition zone, where the temperature suddenly increases dramatically!
  4. d Occasionally field lines burst out of the surface and loop, thereby creating a sunspot pair.
