An image of the Earth-moon-sun system is shown. The moon remains in orbit around Earth because of the force of.

A. Earth's rotation.
B. The Moon's rotation.
C. Earth's gravity.
D. The Sun's gravity.

C. Earth's gravity.

The correct answer is C. Earth's gravity.

To arrive at this answer, we need to understand the principles of gravity and how the moon orbits the Earth. Gravity is a fundamental force of nature that attracts objects with mass towards each other. In the case of the moon, it is pulled towards the Earth due to the Earth's gravity.

The force of gravity acts between any two objects with mass, and the magnitude of this force depends on the masses of the objects involved and the distance between them. In the case of the Earth and the moon, since the Earth is much more massive than the moon, the force of gravity exerted by the Earth dominates.

This gravitational force between the Earth and the moon is what keeps the moon in orbit around the Earth. The moon is constantly falling towards the Earth due to the force of gravity but also possesses enough tangential velocity to keep missing it. This balance between the inward pull of gravity and the tangential velocity of the moon results in the moon's circular or elliptical orbit around the Earth.

So, to answer the question, the moon remains in orbit around the Earth because of the force of Earth's gravity.
