Question

Students are making a moving model of the Sun-Earth-Moon system. The Sun is in the center, Earth is orbiting the Sun, and the Moon is

orbiting Earth.
What important detail should be modeled in the movement of the Moon?
OA. The Moon should orbit Earth once every week.
OB. The Moon should spin at the same rate Earth spins.
OC. The path of the Moon should change every evening.
D. The same side of the Moon should always face Earth.

Answer 1

The important detail in the Moon's movement is that the same side of the Moon should always face Earth.

Step-by-step explanation:

The important detail that should be modeled in the movement of the Moon is that the same side of the Moon should always face Earth. This phenomenon is known as tidal locking. Tidal locking occurs because the Moon takes approximately the same amount of time to rotate on its axis as it does to orbit Earth, resulting in one side of the Moon always facing Earth. This can be demonstrated in the moving model by keeping the same side of the Moon facing Earth as it orbits around the Earth.
