Question

The Earth takes a year to orbit around the Sun. What about the Moon?

Answer 1

Answer

C. The Moon orbits the Earth about once a month

Over billions of years the earth’s gravitational field has tidally locked the moon in orbit so that its rotation about its axis is the same as that of its orbit around the earth.

This process is still continuing as the earth transfers some of its angular momentum to the moon lifting it to a higher orbit by a couple of centimeters a year. As it rises, its takes a fraction longer to complete an orbit, and its rotational speed slows down slightly to match.

The eventual conclusion of this is that the earth also would become tidally locked to the moon, and they will both face each other permanently. But this is going to take that long that the sun will probably have destroyed both the earth and the moon in its red giant phase before this happens.

Hope this helps!\

Answer 2

A because the sun and the moon orbits the earth at the same time that’s how some of us get the moon and the sun at different times because the moon and sun are spaced out so the moon and suns appearances are separated also
