Moon Phases

Moon Phases The moon is akin to a natural satellite off the earth. At night when darkness sets in, it glows by reflecting light from the sun. It revolves around the earth making a complete revolution in thirty days. The revolution ensures that its position in relation to both the earth and the sun varies. The changing positions result in its light being felt differently on earth. For instance, at times it is stronger and its light is felt for longer (Lang 66).
When the moon is in between the sun and the earth as shown in picture eight, its effects are not felt. The face of the earth that is lit receives its light from the sun whose rays are partially reflected back to the sun by the side of the moon. The moon blocks the sun and cannot therefore reflect its rays to the earth. While when the moon is behind the earth as in diagram four, it reflects the rays and lights up a half of the earth for twelve hours from 1800 to 0600.
When the moon positions itself at either 6 or 2, it reflects its rays to a bisected earth. Only that the bisection now runs from east to west. At 6, it lights up the earth from 0000 to 1200 while at 2 it lights the earth from 1200 to 0000. However, the moon light at these times may not last a complete twelve hours as the sun would eventually rises and its effect will obliterate the reflected rays from the moon.
