Astronomy 210 Quiz 3, fall semester 2019
Cuesta College, San Luis Obispo, CA

What time is it when the waxing crescent moon is rising?
(A) 12:00 PM (noon).
(B) 3:00 PM (afternoon).
(C) 6:00 PM (sunset).
(D) 9:00 PM (evening).
(E) 12:00 AM (midnight).
(F) 3:00 AM (wee hours).
(G) 6:00 AM (sunrise).
(H) 9:00 AM (morning).

Correct answer (highlight to unhide): (H)

The waxing crescent moon is highest overhead at 3:00 PM. In a simple model of lunar phases, the moon will take 12 hours from rising to setting, and will take six hours from rising to being highest overhead (at 3:00 PM), so it will have risen at 9:00 AM.
