Why is the same side of the moon always facing Earth?
a. The gravitational pull
b. The inertia of Earth
c. The length of a solar day in comparison to a lunar day
d. The tidal friction locked the moon's rotation to that of Earth
ANS: D
The tidal friction present on Earth keeps the moon facing us. It has locked the moon into rotation with
the Earth. Information can be found in the section The Dynamic Theory of Tides Adds Fluid Motion
