Detailed explanation-1: -What are lunar phases and eclipses? The moonlight we see on Earth is sunlight reflected off the Moon’s grayish-white surface. The amount of Moon we see changes over the month-lunar phases-because the Moon orbits Earth and Earth orbits the Sun.
Detailed explanation-2: -The Moon doesn’t emit (give off) light itself, the ‘moonlight’ we see is actually the Sun’s light reflected off the lunar surface. So, as the Moon orbits the Earth, the Sun lights up different parts of it, making it seem as if the Moon is changing shape.
Detailed explanation-3: -The moon appears to change shape over each month because we see different amounts of the illuminated surface of the moon at different times each month due to the relationship between the positions of the Earth, sun and moon at any particular time.
Detailed explanation-4: -The Moon isn’t actually changing shape-it’s just changing places, and that changes how much of it is lit up by the Sun. The Moon is in orbit around the Earth, meaning it’s constantly revolving around us. It completes one full revolution every 27 days; in fact, the word “month” comes from the same root as word Moon.
Detailed explanation-5: -As the moon orbits the Earth we see these lighted and dark parts of the surface in changing proportions. The changing configurations of illumination on the moon’s surface are known as lunar phases. Throughout human history people have used the phases of the moon as a calendar.
