yes the moon is visible when the sun is up
Sometimes when it is in the morning.
New moon
because the sun dose not line up with the sun
They do. The moon just isn't lit up in the day time but it is still visible.
The amount of the moon's surface that is lit up by the sun varies depending on the moon's position in its orbit. During a full moon, the entire visible side of the moon is illuminated, while during a new moon, none of the visible side is lit up. This is because the amount of sunlight reaching the moon changes as it orbits the Earth.
At a full moon, 100% of the visible surface of the Moon is illuminated by the Sun. Half of the Moon is always illuminated by the Sun, and half of the Moon is visible from Earth. But they're not usually the same half. At a full moon, they are. This happens when the Sun, Earth and Moon are approximately lined up in the sky. If the alignment is exact, we'll have a lunar eclipse because the Moon will pass through the Earth's shadow, which is the only time that less than half of the Moon is lit up.
Well, the sun's light shines on the moon making the moon more visible. It creates barely any light, though. The phases of the moon are the parts of the moon that we can see the sun shining on.
When the moon is completely lit up, it is called a full moon. This occurs when the Earth is between the sun and the moon, causing the moon's entire sunlit side to be visible from Earth.
The moon's visibility depends on its position relative to the Earth and the sun. Sometimes it is on the opposite side of the Earth from the sun, making it full and visible all night. At other times, it is near the sun and invisible in the sky due to its illuminated side facing away from us.
This is known as a crescent moon, which occurs when the moon is positioned between the Earth and the sun. The light from the sun only illuminates a small portion of the moon's surface visible from Earth, creating the crescent shape.
When the moon is full, it's "behind" the earth, that is, in the direction opposite the sun. The three bodies are lined up, with the earth in the middle, like this: Sun ---------------------------------------------------------------------------Earth -- Moon
There are several reasons the moon may not be visible: 1) It is over the horizon from the person observing it - past their line of sight 2) The view of the moon is blocked by something such as clouds (or walls if you are inside) 3) During a "new moon" the side of the moon that is illuminated is opposite the side that would be observed from the surface of the earth - and it is rising and setting with the sun. The moon may still receive a small amount of light reflected from the earth, but under these conditions, the moon is not visible because without that illumination from the sun, the sun is so much brighter than the feeble re-reflected light (from the sun to the earth to the moon) that the moon is not visible. A dramatic example of this is when the moon lines up with the sun to produce a solar eclipse.
