The Sun, the Earth and the Moon are all bodies in the Solar System. Periodic observations, such as the cycle of day and night and the cycle of the Moon's phases, can be seen from Earth.
Which row correctly relates these periodic cycles to the motions of these bodies?
| Period of day and night | Period of the Moon's phases | |
|---|---|---|
| A | the Earth rotates about its axis | the Moon orbits the Earth |
| B | the Earth orbits the Sun | the Moon rotates about its axis |
| C | the Earth rotates about its axis | the Earth orbits the Sun |
| D | the Earth orbits the Sun | the Moon orbits the Earth |
