  6. What was the latitude of the observer? 23 ½ degrees north The tropic of cancer?

  7. This diagram, showing the sun’s positions was drawn in Cheesequake, NJ. In what direction is shadow C pointing? North

  8. What phase is the moon in when it is at position C ? FULL

  9. Which letter represents the waxing gibbous moon? Letter D

  10. At which point in the moon’s orbit would it’s apparent diameter (as seen from Earth) be greatest? Location A

  11. DAILY DOUBLE

  12. About how long does it take the moon to go from position 2 to position 7 ? 18.4 days 29.5÷8 = 3.68 x 5 = 18.4

  13. In the time it takes for the Earth to go around the Sun once, how many times has the Moon rotated on it’s axis? 13.37 times (365 ÷ 27.3 = 13.37)

  20. What is the season in Albany NY as shown in the diagram? Summer

  21. This celestial sphere diagram was made on the day with the greatest duration of insolation. On what date was it made? December 21st

  22. Which location is receiving the maximum duration of insolation on the date indicated by the diagram? Location A

  23. Which location is receiving the greatest intensity of insolation on the date shown in the diagram? Location C

  24. How many high tide are occurring on Earth at any one time? Two

  25. What kind of tides tide are illustrated by the diagram? Neap tides

  26. What kind of tides are illustrated by the diagram? Spring Tides

  27. Which has a a greater effect on the Earth’s oceans (tides), the Sun or the Moon and explain why. The Moon has a greater effect. It is much closer than the Sun so the effect of it’s gravity is stronger.

  28. Exactly how much time goes by from a high tide to the next low tide? 6 hours, 12 minutes and about 30 seconds. (6 hours 12 or 13 minutes is acceptable)

  29. FINAL JEOPARDY Lunacy ?

  30. You are on a rocket traveling from the Earth to the Moon at a speed of 8,042 km/hr. About how many days will your trip require? 2 days 386,000 ÷ 8,042 = 47.99 ÷ 24 = 2
