Why does the earth cast a strait shadow on the moon even though the earth is round?
The earth doesn't cast any shadow on the moon. The moon appears partially in shadow because sunlight only hits it from one direction at a time. It appears perfectly cut in two with a straight line when sunlight is hitting the moon from a 90 degree angle to the earth. The only time the Earth casts a shadow on the Moon is during a lunar eclipse, and in those cases, the shadow, like the Earth, is round.
Will the moon's shadow give the correct time?
You could devise such a system, but it would have serious drawbacks. The moon is not always in the sky, and even when it is it is not always luminous enough to cast a shadow. During the new moon, for example, the moon is in the sky, but we are looking at the full unlit face of the moon without even a slight crescent of luminosity. Your system would probably be made up of very complicated equations even when the moon is luminous.
What causes the larger shadow cast by the moon during a solar eclipse?
The larger shadow cast by the moon during a solar eclipse is caused by the moon blocking the sunlight from reaching certain areas on Earth, creating a shadow that appears larger due to the distance between the moon and Earth.
Each time the moon revolves behind the earth it will pass through the earth's shadow?
This phenomenon is known as a lunar eclipse. During a lunar eclipse, the Earth comes between the Sun and the Moon, causing the Earth's shadow to fall on the Moon, giving it a reddish tint. Lunar eclipses can only occur during a full moon phase.
What esclipes can only happen during a full moon?
A lunar eclipse can only occur during a full moon when the Earth passes between the Sun and the Moon, causing the Earth's shadow to fall on the Moon. This can result in a partial or total eclipse of the Moon.
When are you in the Moon's shadow?
During a solar eclipse. --- ANSWER --- A Solar eclipse occurs when the Moon passes between the Sun and the Earth. The shadow cast by the Moon falls on the earth during 'daytime'. Because the Moon is just the right distance from the Sun it can cover it completely for a very short time as it passes across it's face.

Why can't you see the Moon's shadow except in an eclipse?
A solar eclipse occurs when the moon's shadow falls on Earth. At all other times the moon's shadow simply goes out into empty space; there is nothing to cast a shadow on. The only way to observe the moon's shadow at such a time would be to fly a spaceship into the shadow.
When does the earth's shadow fall on the moon?
The earth's shadow falls on the moon only during a lunar eclipse. Eclipses of the moon can have varying degrees of totality. The earth's penumbra (partial shadow) may pass over the moon, or the umbra (full shadow) may pass over some or all of the moon's surface. All of these happen only at the time of full moon. The moon's regular phases are NOT caused by earth's shadow on the moon, as is incorrectly believed by some.

What happens to the earth in a lunar eclipse?
Nothing dramatic happens on earth during a lunar eclipse.If you happen to be watching the full moon at the time, you notice that over aperiod of a few hours, a shadow creeps across the moon, the moon becomesdark and perhaps even difficult to see for a while, then the shadow creeps offof the moon, and the moon is full again.If you happen to be not watching the full moon at the time, then you notice nothing.
Does the earth's shadow make night on the moon?
No. It causes and eclipse, so it is darker, but not actually night time. Like on Earth, night on the moon is when the a part of the Moon is not facing the Sun. A solar eclipse on Earth, which is caused by the Moon casting a shadow on Earth, causes darkness, but not night time. A solar eclipse can only happen during day time.
Each time the moon revolves behind the earth it will pass through the earth's shadow?
This phenomenon is known as a lunar eclipse. During a lunar eclipse, the Earth comes between the Sun and the Moon, causing the Earth's shadow to fall on the Moon, giving it a reddish tint. Lunar eclipses can only occur during a full moon phase.
Which phase of the moon can a total lunar eclipse occur?
A total lunar eclipse can occur during a full moon phase. During this phenomenon, the Earth is positioned directly between the Sun and the Moon, casting a shadow on the Moon and creating the eclipse.
Why does lunar eclipse last longer than a solar eclipse?
During a lunar eclipse, the Moon is in the Earth's shadow, with the Earth blocking the Sun's light. During a solar eclipse, it is the Earth that is in the shadow of the moon, with the moon blocking the Sun's light from striking a small area of the Earth. The Moon is much much smaller than the Earth, and so has a smaller shadow. This means the smaller lunar shadow results in a shorter solar eclipse. Ancient astronomers used to use the short time of the solar eclipse as a measuring device in the time before clocks existed.
During what moon phase do lunar eclipses happen?
A solar eclipse can occur only at the time of New Moon. A lunar eclipse can occur only at the time of Full Moon.
