Describe the role gravity plays in the phases of the moon. A
The moon’s gravitational pull changes the position of the Earth relative to the moon and sun. This causes the phases of the moon.
B
The sun’s gravitational pull on the moon causes changes in its position relative to the Earth. This causes the phases of the moon.
C
Gravity causes the Earth to spin; this causes the Earth to change position relative to the moon. This causes the phases of the moon.
D
Gravity holds the moon in orbit around the Earth; each month as it orbits the Earth, the moon changes in position relative to the sun and the Earth. This causes the phases of the moon.
