The moon was originally thought of as something just to give us light during the darkness of the night, but as we as humans found out later, it had a much bigger purpose. Don't ask me for why it's like this, it just is. The moon makes the Ocean have waves. Also, if the moon didn't exist, we would have eight hour days, like we did when the Earth was first created. We would also have much more, bigger, mountains because the moon exerts some of its pressure on the Earth, causing it to have smaller mountains than it would have without it.
The moon is 1/4 the diameter of the Earth
The Moon is on the opposite side of the Earth than the Sun is when there is a full Moon.
Definitely the SUN. If the sun were where the moon is in relation to the earth, the earth would be consumed by the sun.
The phase of the moon depends on it position in relation to the earth and the sun. For instance, when the moon is in between the earth and the sun, this is the new of full moon phase.
Because the earth/moon system also moves. Its position, in relation to the sun, changes over the month.
The moon revolves around the earth.

It is between the Sun and the Earth
In a lunar eclipse, the Sun, Earth and Moon are lined up so precisely that the Moon is in the Earth's shadow. Sun . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Earth - Moon

they both have a rocky surface
At the "new" moon, the moon is between the Earth and the Sun. When it is on a direct line between the Earth and Sun, that new moon becomes a solar eclipse.
Viewed from a point on the earth's orbit but very distant from earth,the lineup would look like this at the time of Full Moon:Sun . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Earth . . Moon

What changes from days to day is the amount of sunlight we see on the moon. As the moon orbits the earth and the earth orbits the sun, the sun hits the moon at a different angle in relation to the earth.
Not every relation is a function. But every function is a relation. Function is just a part of relation.
