3. Question 1 - 10 What happens in space that creates ONE DAY on Earth?

4. Answer 1 – 10 1 Rotation of Earth

5. Question 1 - 20 What happens in space to create about ONE MONTH on Earth?

6. Answer 1 – 20 1 Revolution of the moon around the Earth

7. Question 1 - 30 What happens in space that creates ONE YEAR on Earth?

8. Answer 1 – 30 1 revolution of Earth around the sun

9. Question 1 - 40 What force creates predictable planetary motion?

10. Answer 1 – 40 Gravity

11. Question 1 - 50 What happens to the amount of gravity the further objects are from one another?

12. Answer 1 – 50 Gravity decreases

13. Question 2 - 10 Draw a gibbous moon.

14. Answer 2 – 10

15. Question 2 - 20 Why do we see moon phases from Earth?

16. Answer 2 – 20 The position of the Earth, sun, and moon. We see different parts of reflected light depending on where the moon is in its orbit.

17. Question 2 - 30 What is the difference between waxing and waning moons?

18. Answer 2 – 30 Waxing moons have an increasing amount of reflected light that we can see. Waning moons have a decreasing amount of reflected light that we can see.

19. Question 2 - 40 What percentage of the moon is always reflecting sun’s light?

20. Answer 2 – 40 50%

21. Question 2 - 50 Is there such a thing as a dark side of the moon? (meaning one side is ALWAYS dark, receiving no light) Explain why or why not.

22. Answer 2 – 50 No. The moon always has day and night just like Earth. The moon both rotates and revolves, but at the same rate. For every revolution the moon makes around the Earth, the moon also rotates one time.

23. Question 3 - 10 What causes seasons?

24. Answer 3 – 10 The tilt of Earth’s axis, which causes direct and indirect light on Earth.

25. Question 3 - 20 Why is direct light warmer than indirect light?

26. Answer 3 – 20 Direct light is more concentrated (same amount of energy in a smaller area)

27. Question 3 - 30 If it is summer in the northern hemisphere, what season is it in the southern hemisphere?

28. Answer 3 – 30 Winter

29. Question 3 - 40 If the north and south poles get 6 months of light no stop, then why is it still cold during that time of year?

30. Answer 3 – 40 Because the north and south poles always receive indirect light.

31. Question 3 - 50 Identify the season in the northern hemisphere in figure III

32. Answer 3 – 50 Summer

33. Question 4 - 10 Draw a labeled diagram of a solar eclipse

34. Answer 4 – 10

35. Question 4 - 20 Draw a labeled diagram of a lunar eclipse

36. Answer 4 – 20

37. Question 4 - 30 What is the most common type of eclipse?

38. Answer 4 – 30 Lunar Eclipse

39. Question 4 - 40 What phase of the moon do solar eclipses occur?

40. Answer 4 – 40 New moon

41. Question 4 - 50 Why do we not have eclipses every month?

42. Answer 4 – 50 Moon’s orbit is tilted and to have an eclipse, the sun, moon, and Earth must be lined up.

43. Question 5 - 10 What causes tides?

44. Answer 5 – 10 Sun and moon’s gravitational pull on Earth’s oceans

45. Question 5 - 20 About how many tides occur in a day?

46. Answer 5 – 20 4 tides per day (2 high tides, 2 low tides)

47. Question 5 - 30 How long is a tidal day?

48. Answer 5 – 30 24 hours and 50 minutes

49. Question 5 - 40 Draw a picture of a neap tide and a spring tide.

50. Answer 5 – 40

51. Question 5 - 50 Below is a graph of tides over the period of a few months. Explain why some high tides are higher than others at certain points.

52. Answer 5 – 50 The higher high tides occur during spring tides because the moon and sun are working together. The lower high tides occur during neap tides because the moon and the sun are NOT working together.
