The moon's phases result from the changing relative positions of the Earth, Moon, and Sun. It doesn't matter where the moon is when it's half-lit (or in its first quarter); its position relative to Earth and the Sun does matter, however. When the Sun and Moon are aligned on the same side of the Earth the Moon is "new", and the side of the Moon visible from Earth is not illuminated by the Sun. As the Moon waxes (the amount of illuminated surface as seen from Earth is increasing), the lunar phases progress from new moon, crescent moon, first-quarter moon, gibbous moon and full moon phases, before returning through the gibbous moon, third-quarter (or last quarter) moon, crescent moon and new moon phases.
What else can I help you with?
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.
What is the term for the lit shape of the moon?
The general term for the visible lit part of the moon is "the phase of the moon." The visible lit portion can have a crescent shape, a gibbous shape or a "half-moon" (half circle) shape.
How much of the moon is always lit?
About half of the moon is always lit by the sun. This is because only one half of the moon is visible from Earth at any given time. The amount of light that can be seen from Earth reflects different phases of the moon as it orbits.
What is it called when half the moon is lit up?
It is called "first quarter" or "last quarter" when the moon is exactly half-lit.
Is half of the moon always lit?
Half of the moon is always lit by the Sun, but we may not always see that illuminated half from Earth due to our perspective. This is why we observe different phases of the moon as it orbits around Earth.

A week after a full moon the moon looks like a semi circle again what is this called?
About a week after the full moon, the moon is called the last quarter moon and it's "face" appears to be half lit. More than half lit is a gibbous and less than half lit is a crescent.
The half of the moon that is lit by sunlight is?
Visible
How much of the moon is always lit?

Is half the moon lighted up by the sun?
yes half the moon is lit up by the sun
Why can you not see the half of the moon that is lit during a waning gibbous?
you can't see the half of the moon that is lit during a waning gibbous because of the position that the moon is in relation to the sun and earth.
What is it called when half the moon is lit up?
It is called "first quarter" or "last quarter" when the moon is exactly half-lit.
Is half of the moon always lit?
Half of the moon is always lit by the Sun, but we may not always see that illuminated half from Earth due to our perspective. This is why we observe different phases of the moon as it orbits around Earth.
What is a third for quarter?
Half of the moon is lit up.
What is the amount of the moon that is always lit except during a lunar eclipse?
The amount of the moon that is always lit except during a lunar eclipse is about half. This is because half of the moon is always illuminated by the sun due to the moon's orbit around the Earth.
What percent of the moon is always lit?
Unless there is a lunar eclipse, half of the moon is always lit by the sun. Sometimes we see the lit half dead on (full moon), sometimes side on (half moon) and sometimes we don't see any of the lit surface (new moon) - usually we see something in between.
