Why is the first quarter moon phase called that?
At "half Moon" we see half of the Moon's hemisphere that is facing Earth. But "half Moon" isn't what astronomers call that phase of the Moon. It is called a "quarter Moon" phase. That's because the Moon has completed one quarter (at First Quarter phase) or three quarters (at Third Quarter phase) of an orbit around the Earth since new Moon. (Another possible reason is that we see a quarter of the total surface of the Moon at these phases.)
How much time elapses petween each of the four principle phases of the moon?
It takes about 7 days for the moon to transition between each of the four principal phases: new moon, first quarter, full moon, and last quarter.
What is the name of the moons changing shapes?
The apparent changes in the moon's shape are called waxing and waning. The moon is waxing when it goes from a new moon (you can't see it) to a full moon and it is waning as it goes from a full moon to a new moon. What appears to us as a change in shape is caused by the position of the moon with respect to the Earth and the sun. When the Earth is completely between the moon and the sun, no light is able to hit the moon and we see a new moon. When the Earth is partially between the sun and the moon. Lastly, when the Earth is not between the sun and the moon, we see a full moon.
How a waxing quarter moon is different from a waning quarter moon?
Crescent: The visible portion of the moon is less than half of the full disk.Gibbous: The visible portion of the moon is more than half of the full disk, but not 100% full.
How much space is between the moon and sun?
The average distance between the moon and the sun is 150 million kilometers.
How much time does it take for the moon to go from a waxing crescent to a wining crescent?
The moon is a waxing crescent from New Moon until First Quarter, and a waning crescent fromThird Quarter until the next New Moon.So it's a crescent from Third Quarter until First Quarter, and not a crescent from First Quarteruntil Third Quarter. Each of these is 1/2 of the cycle of phases, or 1/2 of 29.53 days = 14.77 days .
Why is the first quarter moon phase called that?

(Another possible reason is that we see a quarter of the total surface of the Moon at these phases.)
How much time elapses between each of the four principal moon phases?
The time between each principal moon phase is roughly a week. Specifically, from New Moon to First Quarter Moon is about 7 days, from First Quarter to Full Moon is another 7 days, from Full Moon to Last Quarter Moon is approximately 7 days, and from Last Quarter back to New Moon is around 7 days as well.
How much of the moon are you seeing when it appears half lit?
When the moon appears half lit, you are seeing exactly half of its surface. Half of the moon is illuminated by the sun, while the other half is in shadow. This phase is known as the first quarter when the moon is waxing, and the third quarter when the moon is waning.
The moon looks like a half-circle about a week later on another clear nght you go outside and you cannot see the moon predict how much of the moon you will see after another week passes?
The obviously desired answer is "a half-circle", because you originally saw the 3rd quarter moon, and a week later the Moon would have been new. So after another week, you would see the first-quarter moon. However, if you go outside on a clear evening, you will not see the third-quarter Moon, because the third-quarter Moon does not rise until midnight. So if you saw the third quarter moon high in the sky, it would have been at about 3AM. I don't know about YOU, but I'm hardly ever up at 3AM, and if I am, I'm inside. And if you do not see the Moon at night, all that tells you is that you don't see the Moon. Depending on the time, it may not be up yet, or it may already have set.

How much is quarter plus a third?
7/12
How a waning quarter moon is different from a waning quarter moon?
Not by much at all. In fact, you'd swear that they were virtually the same identical thing.
What are the phases of the moon?
The phases of the moon are determined by how much of the illuminated half of the Moon can be observed from Earth (from which only one face is visible). Beginning with the New Moon, when the Moon is directly between the Earth and the Sun, the phases are:New moon (0% illuminated)Waxing crescent moon (1% to 49%)First quarter moon (50%)Waxing gibbous moon (51% to 99%)Full moon (100%)Waning gibbous moon (99% to 51%)Last quarter moon (50%)Waning crescent moon (49% to 1%)(and back to New)(See the related links below for more information including a pictorial.)
How much is a third and a quarter?
7/12 or seven twelfths
What is a half moon?
A half moon is a lunar phase where half of the moon's visible surface is illuminated by the sun. This occurs when the moon is positioned at a 90-degree angle relative to the Earth and the sun. Half moons are also known as the first quarter moon or third quarter moon, depending on which side is illuminated.
What are the 4 phases of moon?
The four phases are crescent, gibbous, waxing, and waning. Remember, the phases refer to how much light the moon reflects and its positioning.These 4 phases are also referred to asNew MoonFirst Quarter MoonFull MoonLast Quarter Moon
