Why would an observer on the Earth see a complete cycle of the phases of the moon in approximately one month?

because of the tilt of both the moon and the earth on their rotation axis

An observer on Earth sees the phases of the Moon because?
It moves on its axis.
How many types of moon phases can be seen by an observer on the earth?
Eight types.
To an observer on the moon able to see earth how long would one full cycle of earth phases be?
It would be about 29.5 earth days. Or, precisely the same length of time as a full cycle of moon phases.
What are the various phases of the Earth?
The apparent 'phases' of the earth depend entirely on where the observer is located. If the observer is standing on the moon and looking at the earth, he will see the earth go through exactly the same phases as we see the moon go through ... but they will be COMPLEMENTARY. At any moment of the month, the shape of the ILLUMINATED portion of the moon ... seen from earth ... is exactly the same as the DARK portion of the earth as seen from the moon. Combine the illuminated moon phase of the earth-bound observer with the illuminated earth phase of the moon-based observer, and they always add up exactly to one full illuminated disk.
What is the definition of the moon phases?
The phases are the different shapes that the Moon seems to have when it is observed from Earth. This is due to the location of the Moon in its orbit, so that we only see a portion of its surface as illuminated by the Sun.
What can be seen from earth's orbit other than the moon?
The moon's phases can be seen from the earth, but not by an observer on the moon. Similarly, the earth's phases can be seen from the moon, but not by an observer on the earth.

How the moon would appear to an observer in space during its revolution. Would phases be observable?
Yes. Unless the observer was on the back side of the moon, or on the opposite side of the earth from the moon, he/she could see the same phases that we see here on earth.

As the moon moves around the earth what does an observer on earth see?
He sees the phases of the moon. A varying amount of the sunlit surface is visible as the moon goes through its phases, having increased or decreased illumination with a curved boundary.
How are moon phases affected by the observers location?
As long as the observer is some place on the earth, his locationhas essentially no effect on the moon phase that he sees.
How many earth days does it take for the moon to travel around earth?
The moon makes one complete orbital revolution of the earth in 27.32 days, and displays a complete cycle of phases every 29.53 days.
Why do planets have phases similar to lunar phases?
The planet Venus has phases similar to the moon's phases because of its orbit around the sun, inside the orbit of the Earth. Because of its particular orbit, an observer from the earth is?æable to see various phases.
Does it take a month for the moon to travel all the way around the earth?
That's approximately the time it takes the Moon to orbit the Earth.
What did Galileo find in his scientific observations that convinced him that Ptolemy had been wrong?
When Galileo observed that there are satellites which orbit the planet Jupiter, this was clear evidence that not everything orbits the Earth.
