Because the Earth is obscuring part of the moon's disc from the sun - creating a partial shadow.
Full Moon...When The Side Of The Moon We See Is Fully Lit.
Because the Earth is not always between the Sun and the Moon where you can see the fully lit side of the Moon. Try lighting a ball with a flashlight in a dark room. You can only light half of it at a time.
Despite a popular belief, the Moon is not only seen at night. Depending on where the Moon is in its orbit round the Earth, may mean the Moon is in the sky during daylight. The bright sky makes it very difficult to see the Moon.
Some people expect to see the Sun during the day, and the Moon in the darkness of the night. But, depending on the position the Moon has reached in its orbit round the World, the Moon may appear during the day. Once the Sun is shining brightly, the Moon is less, if not impossible to see, because of the brightness of the daylight. Early dawn or twilight, when the sky is not too bright is the best time to see that the Moon, in all its phases, can appear during the day.
You can see the moon for about 8 hours in the day
Yes, it can be argued that Moon has a day time and night time. Day time is when the moon is shining bright above the sky, night time is when the moon is dark. Hence the term "Dark Side of the Moon".
You can see the moon sometimes
The only day on which you generally do not see the Moon is on the day of the "new" moon, when the Moon is quite near the Sun in the sky. On any other day of the 29-day cycle, you will - weather permitting! - be able to see the Moon, either in the morning or in the evening.
The moon
The lighted side of the Moon seen from Earth is the same during a full moon. At this phase, the Earth is positioned between the Sun and the Moon, allowing us to see the entire illuminated portion of the Moon's surface. This alignment results in the Moon appearing fully round and bright in the night sky.
If you can see a full moon at your position on Earth, then someone on the exact opposite side of the world will see a new moon. This is because the full moon is when the side of the moon facing Earth is fully illuminated by the sun, so the side facing away from Earth is in shadow.
You can see the moon during the day because the Earth is round and the moon is always in the sky, even when it's not visible at night. The moon's position in the sky changes throughout the day due to its orbit around the Earth, allowing it to be visible during daylight hours.
