12. Diagram 1 shows the Moon in its orbit at four positions labeled A, B, C, and D. Diagram 2 shows a phase of the Moon as viewed from New York State. At which labeled Moon position would the phase of the Moon shown in diagram 2 be observed from New York State? (1) A (3) C (2) B (4) D X

13. It’s all about the motions…

14. Takes 29.5 days! When moon is back where it started (27.3 d later) the position to the sun has changed! While moon revolves around Earth, Earth is revolving around sun.

18. Which phase?

22. There is about a 5 o angle, which prevents a monthly eclipse!
