The different phases of the moon that we see from Earth are caused by the moon's orbit around the Earth and the amount of the moon's surface that's illuminated by the Sun. Here are the steps that explain this process:

1. The moon orbits the Earth approximately once every month. As it does so, the amount of the moon's surface that's illuminated by the Sun changes, and this causes the moon's appearance to change.

2. When the moon is between the Earth and the Sun, the side of the moon that's illuminated by the Sun is facing away from Earth. This is called a new moon, and we can't see it from Earth.

3. As the moon continues its orbit, more of the illuminated side becomes visible from Earth. This is called waxing. When half of the moon's surface is illuminated, this is known as the first quarter.

4. When the moon is on the opposite side of the Earth from the Sun, the entire side of the moon that's facing Earth is illuminated. This is called a full moon.

5. After the full moon, the visible illuminated surface starts to decrease. This is called waning. When half of the moon's surface is illuminated again, this is known as the last quarter.

6. Finally, the moon returns to the new moon phase, and the cycle starts again.

So, the different phases of the moon that we see are caused by the moon's orbit around the Earth and the changing amount of the moon's surface that's illuminated by the Sun.
