The lunar phases vary cyclically as the Moon orbits the Earth, according to the changing relative positions of the Earth, Moon, and Sun. The boundary between the illuminated and unilluminated hemispheres is called the terminator. The lunar effect is a theory which overlaps into sociology, psychology and physiology suggesting that there is correlation between specific stages of the Earth's lunar cycle and deviant behavior in human beings. It is a pseudoscientific theory, however.

The dotted line from the earth to the moon represents your line of sight when looking at the moon. The large moon image shows what you would see at that point in the cycle. For the waning gibbous, third quarter, and waning crescent phases you have to mentally turn yourself upside down when imagining the line of sight. When you do this, you'll "see" that the illuminated portion is on your left, just as you see in the large image.
Have you ever doubted what creates the moon phases? It is known that its appearance evolves over times. But why? The best method to understand the phases of the moon is to scrutinize the aspects of astronomy. The typical reason given for the cause of the moon phases is that we are observing the shadow of the Earth on the Moon!
