Astronomy 210 Quiz 1, fall semester 2013
Cuesta College, San Luis Obispo, CA
Approximately how much time elapses between moonrise and moonset?
(A) An hour.
(B) Several hours.
(C) 12 hours.
(D) 24 hours.
(E) Several days.
(F) One week.
(G) Several weeks.
(H) 28 days.
Correct answer (highlight to unhide): (C)
Earth's rotation causes the moon to rise and to set, and assuming that the moon's revolution around Earth is a much slower rate (a month-long period) compared to Earth's rotation (24-hour period), then the moon will take approximately 12 hours from rise to set.
