2. What are the four main phases of the moon?

3. New 1 st Quarter 3 rd Quarter Full

4. What is it called when the moon blocks the sun from the Earth?

5. Solar Eclipse

6. Why do we only ever see one side of the moon?

7. The moon rotates at the same rate at which it revolves.

8. What is a spring tide and how often does it occur?

9. 1.A spring tide is an extra-high high tide. 2. It occurs twice per month. During a New and Full moon.

10. What is a Neap Tide and how often does it occur?

11. 1.A neap tide is an extra-low high tide. 2. It occurs twice per month. During a 1 st and 3 rd Quarter Moon.

12. Why is a satellite-based telescope better than an Earth-based telescope?

13. Satellite telescopes do not have to view the universe through the atmosphere. The atmosphere blocks our view.

14. What did Penzais and Wilson discover about the universe?

15. They discovered background microwave radiation which is possibly energy left over from the Big Bang.

16. How do scientists know that the universe is expanding?

17. Red Shift of Spectrums

18. What does red shift tell you about the universe?

19. It is expanding (stretching waves = longer wavelengths = lower frequencies)

20. What will blue shift tell you about the universe?

21. It is contracting (contracting waves = shorter wavelengths = higher frequencies)

22. What information can you obtain from the H-R Diagram (Name at Least 3 Things)?

23. Size/Type of Stars Color/Temperature of Stars Brightness of Stars Age of Stars

24. What does the Main Sequence of Stars Represent?

25. Stars that are of average brightness and temperature. Most of the stars viewed within our universe fall under the category of Main Sequence.

26. Stars can fuse atoms of up to what element?

27. Iron (Fe)

28. Describe the life cycle of an average-sized star.

29. Nebula  Protostar  Main Sequence Star  Red Giant  White Dwarf  Black Dwarf

30. Describe the life cycle of a giant star.

31. Nebula  Protostar  Super Giant  Supernova  Black Hole or Neutron Star

32. In what shape does the Earth (and all other planets) orbit the sun?

33. Elliptical (oval)

34. What are the two phenomena responsible for keeping the Earth (and all other planets) in orbit around the sun?

35. Inertia and Gravity

36. Why do we experience seasons on Earth?

37. Tilt and Revolution

38. Describe the positions of the sun, Earth, and moon during a lunar eclipse.

39. S E M

40. Describe the positions of the sun, Earth, and moon during a solar eclipse.

41. S M E

42. Describe how the sun gets its energy.

43. Nuclear Fusion ( 4 hydrogen fuse to form 1 helium and ENERGY!)

44. Name at least three differences between the inner and outer planets.

45. Inner Warm Rocky Short Years Thin Atmospheres Outer Cool Gaseous Long Years Thick Atmospheres

46. What is a meteoroid and where does it come from?

47. 1.A meteoroid is a chunk of rock found in the solar system. 2. The usually come from the debris left over from a comet’s tail

48. What are comets and where do they come from?

49. 1.Comets are large chunks of ice, rock and dust. 2. They come from the outer reaches of the solar system (Kuiper Belt or the Oort Cloud)

50. Explain how a meteoroid, meteor, and meteorite differ.

51. 1. Meteoroid-found in space. 2. Meteor- streak of light found in the Earth’s atmosphere 3. Meteoroid-Found on the surface of the Earth.
