WHY DOES THE MOON APPEARS TO CHANGE SHAPE?

                           Each month it seems as though the moon changes shape. Of course, that is not really the case. Only the part of moon that is both turned towards the Earth and lit by sun is visible from Earth. The moon orbits the Earth once every 27.3 days, a lunar month. As the moon also takse exactly 27.3 days to turn on its axis, the same side of the moon is always turned toward the earth. The amount of moon that can be seen changes as the moon position changes.
           It is this change in the amount of the moons face which can be seen from the earth, that makes the moon look as though it is changing shape. Our word month comes from moon although our calender months are no longer linked to the phases to moon.

  2. It is very interesting to learn about those phenomena that we can easily observe, but until the end we do not understand how this happens.
