  1. Unit 3 Review

  2. 1 • What force was represented when the pepper moved to the middle of the swirling plate?

  3. 2 • What event did the floating pepper represent when it moved to the outside of the plate?

  4. 3 • Gravity pulls in on the material that makes up stars until what process occurs?

  5. 4 • How large is our planetary system?

  6. 5 • What does S.N.A.D. stand for?

  7. 6 • What is the approximate mass of the Solar System?

  8. 7 • What is the approximate mass of the Milky Way Galaxy?

  9. 8 • What is the difference between the formation of a planetary system and a galaxy?

  10. 9 • How old is the sun? The Solar System?

  11. 10 • Early astronomers (Greeks, Egyptians, and such) considered the Sun to be a planet. Why do you think they did this?

  12. 11 • List the layers of the Sun. Describe what goes on in each layer.

  13. 12 • Is the atmosphere of the Sun considered a part of the Sun? Give your reasoning.

  14. 13 • How often does proton-proton fusion happen in the Sun? (times per second)

  15. 14 • What is the wattage (energy output) of the Sun?

  16. 15 • How many layers does the atmosphere of the Sun have? List them.

  17. 16 • What is the temperature of the coolest and closest layer of the atmosphere? What molecules exist there that are not found anywhere else on the Sun?

  18. 17 • What color is the next layer of the atmosphere of the Sun?

  19. 18 • What force overtakes what other force in the next region?

  20. 19 • What does the temperature jump to in the previously described region and why does it do this?

  21. 20 • Is the Corona (Crown) of the Sun always present? Why can we see or not see it at all times?

  22. 21 • There is only one manmade object so far that has ever left the influence of the Sun. What is that object and when did it leave the heliosphere?

  23. 22 • About our solar viewer, what did we replace the foil with?

  24. 23 • What is a sunspot and what makes it cooler than the rest of the Sun?

  25. 24 • What is the difference between the Umbra and Penumbra of a sunspot?

  26. 25 • What does each granule on the surface of the Sun represent?

  27. 26 • What object is the sun like (think back to physics and magnetism) and how is it like that object?

  28. 27 • What is the relationship between light and heat on Sunspots? (How much more heat makes how much more light?)
