Why does the moon change its shape?

                                                                    MOON

The moon ,which cause max and min tides on earth,is a sphere.It does not change its shape;only
view of it changes.The reason is that unlike other stars the moon doesn't produce light,but
only reflects also.(SUN LIGHT)
Since the moon goes around the earth once in a month,the orientation of the moon ,the sun and the earth respective to another  changes. For this reason the half part of the moon can not  always be
seen from earth.
Sometimes we see it full size ,sometimes half and sometimes nothing.the side of the moon that face us remain on the same.We can see the craters and dark spots on the moon which are known as MARES
