Which statement describes how earth compares to the moon? earth has more inertia than the moon. the moon has more gravitational pull than earth. the moon rotates at a constant speed while earth's speed varies. earth and the moon will not change their motion when acted on by a force.

The moon rotates at a constant speed while Earth's speed varies.

1. The Earths pull is 86 times that of the moon.

2.Lets just hope no force acts on the earth and moons motion otherwise we are in trouble.

Option C, The moon rotates at a constant speed while Earth's speed varies.

Explanation:

The moon rotates around the sun with a changing velocity as its direction of motion changes at every instance. However, the speed with which moon rotates remains constant.

Earth moves on an elliptical path around the sun. Hence, when earth is close to the sun (on minor axis of the elliptical path, perihelion) it rotates at a fast speed. While when it is away from the sun (aphelion) it rotates at a slow speed.

Hence, option C is correct.
