The Moon undergoes synchronous rotation,and as a consequence the:
A) rotational period of the Moon equals the orbital period of the Moon around Earth.
B) rotational period of the Moon equals the rotational period of Earth.
C) rotational period of the Moon equals the orbital period of Earth around the Sun.
D) Moon does not rotate as it orbits Earth.

Question

Quizplus · Accepted Answer

Synchronous rotation means that one side of the Moon always faces Earth, and as a result, the Moon's rotational period is equal to its orbital period (about 27.3 days), which is choice A. Choices B and C are incorrect because the Moon's rotational period does not match with Earth's rotational period or the Earth's orbital period around the Sun. Choice D is also incorrect as the Moon does rotate on its axis, but the period of rotation is equal to its period of revolution around Earth.
