Lesson 9.6 Moon Phases

Question 3 • (OC27) Earth/Space Sci-2001310-S2-Nelson

Stella tells her friend Gale that the Sun never shines on one side of the Moon and that is why people talk about "the dark side of the Moon.” What should Gale say to Stella?

Answer
A
Gale should say that the motion of the Moon causes the same side to always face the Sun.
B
Gale should say that the far side of the Moon isn’t always dark; we just never see it from Earth.
C
Gale should say that it used to be true that one side is always dark, but that this is not true anymore.
D
Gale should say that the reason one side of the Moon is called dark is because it no longer emits light.

Explanation

The Moon rotates as it orbits Earth, so sunlight reaches both its near and far sides at different times. The far side is not permanently dark; “dark side” is a misleading name for the side we do not see from Earth. Therefore, Gale should say that we just never see the Moon’s far side from Earth.
