Moonquakes occur MOST often when the Moon is near perigee (at its closest approach to Earth). The reason is
A) increased tidal distortion of the Moon by Earth.
B) higher probability of impacts on the Moon of meteoroids that have been accelerated by Earth at these lunar phases.
C) increased speed of rotation of the Moon at these times and consequent reduction of the gravitational force on the surface.
D) increased sunlight on the Moon's surface at these times.

Question

Quizplus · Accepted Answer

Moonquakes are more frequent during perigee due to the increased tidal distortion of the Moon by Earth's gravitational pull, which stresses the Moon's crust and can cause quakes.
