Final answer:
Shadows on the moon face different ways because of the moon's varying surface composition.
Step-by-step explanation:
The correct answer is Option 2: Because of the moon's varying surface composition.
The varying surface composition of the moon causes shadows to face different ways. Different materials reflect and absorb light differently, which affects the direction of the shadows. For example, rocky areas may have shadows facing one direction, while flat areas may have shadows facing another direction.
It's important to note that the rotation of the moon (Option 1) does not directly affect the direction of shadows, although it does cause day and night cycles on the moon.
