  1. CAAP A REVIEW

  2. What is a SUNSPOT?

  3. Dark area on the sun. • Area of intense magnetism

  4. How many sunspot cycles do you see in the Graph?

  5. FIVE Sunspot cycles

  6. What is an aurora?

  7. It is charged particles form the sun hitting the magnetosphere

  8. Does an increase in solar activity affect auroras?

  9. When there is an increase in Solar activity there is an increase of auroras.

  10. What is a solar flare?

  11. solar flare • Charged particles ejected from the sun

  12. How is earth affect by solar flares?

  13. Earth is affected by loss of communication, northern lights

  14. Nuclear Fusion reactions that combine with smaller nuclei to form more massive ones are the source of the sun’s energy. • True or false

  15. TRUE

  16. What is a prominence?

  17. Prominence • Large arch into the corona of charge particles.

  18. Which stars have the highest absolutes magnitude?

  19. Supergiants have the highest magnitude

  20. By looking at the x-axis and the y-axis, can you tell in which direction do stars move when their temperature and absolute magnitude are the lowest and coolest? (Remember: the higher the number of absolute magnitude the dimmer the star)

  21. Down to the Right

  22. What color of star is most likely found on the main sequence?

  23. Yellow Stars

  24. What type of star, does a main sequence star become when it loses its energy?

  25. Supergiant ->white dwarf

  26. What two forces have to equal each other for a star to become stable?

  27. Gravity and Fusion

  28. We live in the spiral arm of which galaxy?

  29. Milky way

  30. What is the Big Bang Theory?

  31. Big Bang • The Idea that all matter was created in one massive explosion

  32. What does this chart represent?

  33. Big Bang

  34. What does cosmological redshift measure?

  35. Outward expansion of the universe

  36. Explain how the presence of cosmic background radiation supports the big bang theory?

  37. We can see the universe was small and warm but has expanded outward and cooled

  38. The expansion of the universe is measured by cosmological redshift. • True or False

  39. TRUE

  40. The Doppler Redshift is a measurement of celestial objects moving outward from Earth. • True OR False

  41. True

  42. What process formed the solar system?

  43. From solar nebula-> gravity forces the nebula to begin fusion-
