Step-by-step explanation:

The phase of the moon depends on its position relative to the sun and Earth. The phases change as the moon revolves around Earth, different portions of the moon's sunlit surface are visible from Earth. Thus, from the perspective of Earth, the appearance of the moon changes from night to night.
