How much of the moon is always in the dark?
The moon is always half dark. The half facing the sun is light, the other half is dark.However, during a lunar eclipse, the moon would be temporarily all dark since it is in the shadow of the earth.
Why does the earth have a shadow?
The Sun is the MAJOR source of Light on Earth. Therefore its position relative to the Earth affects the LENGTH of Shadows cast by objects on or near the Earth. The HIGHER the Sun appears in the Sky, the SHORTER the LENGTH of the cast Shadow. When the Sun is DIRECTLY overhead there is NO Shadow cast.
How does the shadow of the earth on the moon have a straight line through it when its half full?
The shadow of the earth never falls on the moon when the moon is half full.
What is a half moon?
because the part of the earth that is having 'daytime' is blocking the sun from the moon. since the moon revolves around it can get a little bit of sun. What you see of the moon is how much sun light is hitting the moon.
Why does a lunar shadow never cover the earth completely?
because the a lunar eclipse is therefore visible over about half the earth's surface

How much of the Moon's surface is illuminated by the sun at any time regardless of how much of that light can be seen from earth?
One half unless it is in the earth's shadow

Why do we have sunsets?
Because we have only one sun in our solar system, because Earth is roughly spherical (like a ball), and because light almost always travels in straight lines (except for a little bit of refraction caused by our atmosphere), the sun is always shining on half of Earth, where it is daytime, while the other half of Earth is in Earth's shadow (nighttime). Since Earth is always rotating on its axis, part of the line between the daytime half and the nighttime half is rotating into Earth's shadow and part of the line is rotating out of Earth's shadow into the sunlight. At the places that are rotating into the sunlight, the sun appears to be rising, and at the places that are rotating into darkness, the sun appears to be setting.

What part of earth has night at the same time?
Half the Earth is light, the other half is dark. Anywhere on the dark half experiences night.
Why can only half of the earth be in daylight at any one time?
OK, I did a project on this last year! :) The sun gives all it's rays onto the earth and other planets, but it can only shine on one half of the earth because there is only one sun. If there was another sun on the other side of the earth, there would be no night time. You can understand this easier if you get a globe and hold it in front of a light. half the earth will be in light, when the other isn't because the other half of the earth is in the shadow. A ball can work too if you don't have a globe. Also if the earth was flat, you could get it all in daylight at the same time. Hope this helped! :) The first answer hits the nail on the head but I'll add a bit to it. The moon is a small version of the sun. The moon produces what we call nightlight/moonlight. So technically speaking, when darkness is simply the absence of light, the earth technically is never dark. It just has brighter light on one half due to the sun being brighter than the moon.
What is the difference between being in the umbra and penumbra of the shadow the moon casts on earth doing a solar eclipse?
The umbra in a lunar eclipse is the part of the earth's shadow from the sun that completely blocks the light from the sun from falling on the moon.The penumbra is the part of the shadow that only partially blocks the light. The antumbra is the continuation of the umbra beyond the point where the edges of the penumbra intersect. These various regions of light and shadow occur when the light source and shadow causing bodies are not point sources or point shadows.
Why do we have a sunset?
The sun does not go down, the Earth spins around. You were at a spot where the Earth turned to the point that you can't see the sun anymore. However, every morning, the Earth finishes its rotation, letting you see the sun again.
Why does half of the moon always get light?
Because the Moon is spherical (like a ball) and the Sun shines from the middle. So half of the Moon is sunlit. Except for about 3 hours twice a year, when the Moon passes into the Earth's shadow, when the Moon gets no light at all. We call this a "lunar eclipse".
Are Solar eclipses caused by the earths shadow?
Probably, I mean what else could there be (or the Earth makes a shadow covering the half that doesn't face the sun)
