How can the sun and the moon be out at the same time if while light on one side it is dark on the other?

The earth orbits the sun; the moon orbits the earth. The cycles of rotation are different meaning that the moon will orbit the earth many times every year. This means that it will very often be in a position to be seen during the day. The moon itself has no axial rotation so on earth we always see the same side of the moon.

Obviously the moon has to be between the Sun and the\nEarth, so maybe they want you to say, "when the Moon is new".\nNote that this is the *opposite* of a full moon.

the moon rotates around the earth and the earth rotates around the sun, and the earth rotates on it's axis.  sometimes that places the moon on the 'daytime' side of the earth.  depending on where it is relative to the sun that day, we'll see a crescent moon, or half moon—sometimes we won't even see the moon though it's there.\n\nimagine you are the earth and you are holding a heavy ball (the moon) on a rope and spinning around in a circle fast enough to see the ball up in front of you, while at the same time walking in a circle around a house (the sun).  quite often, you would see both the ball and the house at the same time.\n\n//

That has happened for the past week, right? Well, when the moon is behind the earth relatively to the sun, it's seen as full; but along the next 2 weeks the moon is going to make her way in the direction of the sun, so when it's halfway it's seen half-illuminated (in the half looking to the sun), in broad daylight... that's the phase "last quarter moon". Slowly day by day you'll notice the moon gets thinners and thinner, and closer to the sun... until one day you don't see it - that's because she's very near the sun from where we stand - and we see her "behind" which is not illuminated.

When the light from the sun hits the moon, it is reflected to us which causes "Moonlight". This is the same light and source that allows us to see a bit of the shadows on the moon. \n\nThe suns and moons position in relation to one another is also what gives us the phases of the moon.  When the moon is directly opposite of the sun (with Earth not being directly in the line of sight) this gives us our full moon. \n\nIn short, there is only one type of light on the moon, the suns light hitting the moons surface.

You mean the moon and the sun, which is true\nsometimes, but there are also eclipses where\nthe moon is smaller than the sun, so a small\nring of light is left uncovered (called an annular\neclipse)...\n\nBy a stroke of amazing coincidence, both the\nmoon and the sun are approx 108 times as\nfar from the earth as their diameter, so they\nappear the same size in the sky... 108 is a\nmystic number in spirituality, so I doubt if this\nis really a coincidence!

Sunlight from the Sun would have to reflect off something in space in order for that region of space not to appear black.  For example the Moon doesn't look black because Sunlight is reflecting off its surface.\n\nSpace is for the most part black since there is an absence of material that can produce or relfect light there.

because the sun's gravitational pull is much greater than the earth's...same reason the moon goes around the earth and not the other way around

Yes - the moon is far away, and the earth spins around it's own axis, creating day and night time. The moon would move a little 1/56 of phase shift during the half day it would take for the other half of earth to see the moon, but it's not noticeable.

No.  The angle between the sun and the moon as viewed from the earth is 180 degrees for the full moon pahse.  This means that the full moon and the sun are always on opposite sides of the earth.\n\nSince the moon is not always "in plane" with the sun, and your horizon is not perfect, it may be possible on occasion, depending on the geography of the horizon, and one's latitute to see the full moon rising as the sun is setting, or to see the full moon setting as the sun is rising.

Day or night, you are seeing the portion of the moon that is facing the sun. The only time Earth blocks illumination of the moon is during a lunar eclipse, which happens only two or three times a year.

Moses and Campbelp have it right--the fluorescent light is closer and of larger apparent size (especially if it is a long tube!).  The sun's shadows are not perfectly sharp because it has some size.  This is the cause of the "penumbral" lunar eclipse, when the moon dims but is not fully eclipsed, as it passes through the dim but not dark portion of the Earth's shadow (the penumbra--the darkest part of a shadow is the umbra).

1.  Longer shadows\n2.  The moon's gravitational pull and the sun's gravity also\n3.  The sun\n4.  counterclockwise, west, east\n5.  D\n6.  The Earth's Rotation\n7.  The earth is at a slant compared to it's solar revolution, so the earth recieves more sunlight in different areas, and the earth's solar revolution isn't a perfect circle, AND the earth wobbles\n8.  The sun's reflection causes the moon to light up, and so the sun's position determin's the shape.\n9.  the earth and the sun and the moon have to line up in a linear fashion, perfectly, not just good enough for a full moon

Think of it this way.  The earth has 4 sides, just because ONE OF THEM is looking at the moon and the Sun is facing another side, means nothing.  There is over 90,000,000 miles between the earth and the sun, so we only get a fraction of a percent of its total output of energy.  The Moon while it is in space going around us, is no longer "blocked" by the earth and can now receive its share of light from the sun.  HOWEVER, you may be surprised to learn that the albedo (reflection of light) from the moon is mostly caused by the Earth as much as the Sun.  That is, where it is now daylight on Earth is relecting off of the moon also.

I think it would because while the sun and the moon both shine, the moon is not boastful and sometimes hides away only showing it's light some of the time and, even then, only softly. Doesn't that seem beautiful to you?

Here is a very simple and precise explanation with good illustrations\nhttp://home.hiwaay.net/~krcool/Astro/moon/moonorange/

You always see the same face, you can`t see the dark side.\n\nBut you can see the moon different ways up depending on where in the world you are...\n\ne.g. I live in the uk and am used to seeing moon a certain way up. When I travelled to Singapore the moon seemed to be on it`s side. When I went to Australia, the moon looked completely upside down.\n\nBut it was the same face.
