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.


What is a gibbous moon?

The phase of the Moon during which more than half, but less than all, of the visible hemisphere of the Moon is illuminated by sunlight. A gibbous moon is between a full moon and a half moon, or between a half moon and a full moon. There can be two gibbous moons: waxing and waning. " A gibbous moon is one of the phases of the Moon when the size of the illuminated portion is greater than half but not a full Moon. The period between a first quarter moon and a full moon is known as a waxing gibbous moon, because the illuminated region of the Moon is increasing from day to day. After it becomes a full moon, but hasn't reached the last quarter, the Moon is called a waning gibbous moon."


What term is used to describe the decrease in the visible portion of the moon?

The term used to describe the decrease in the visible portion of the moon is "waning." This occurs as the moon transitions from a full moon to a new moon phase.


What is the term used for the moon that is almost full but not quite?

A moon between half and full is called 'gibbous'.


What does the term "half moon phase" mean in relation to the lunar cycle?

The term "half moon phase" refers to the lunar phase when half of the Moon's visible surface is illuminated by the Sun, creating a shape that resembles a half circle. This phase occurs halfway between a new moon and a full moon in the lunar cycle.

During the waxing gibbous phase is the amount of illumination increasing or decreasing?

When the visible bright part of the Moon is increasing in size, the term "waxing" is used. When the visible part of the Moon is less and less illuminated each night, the term "waning" applies.


Why is the phase in which half the moon is visible called a quarter moon?

Half of the Moon you cannot see because it faces away from Earth. Half of the side you could see is in darkness at "half Moon". That makes 3/4 of the Moon invisible and 1/4 visible. Hence "a quarter Moon" is visible. Another viewpoint: No, that's not really the answer. This is the answer: Let's start with "New Moon". Later, at "Full Moon", the Moon is halfway through its cycle of phases. Halfway between these two phases we see a half Moon. That's called the "first quarter" phase, because the Moon is a quarter of the way through its phases. So, that's why we see the half Moon at a "quarter" phase. It does cause confusion.

What is the significance of the term "what is after a new moon" in relation to lunar phases?

The term "what is after a new moon" refers to the phase of the moon that comes after the new moon in the lunar cycle. This phase is known as the waxing crescent, where the moon starts to become visible again in the sky. Understanding this term helps in tracking the progression of lunar phases and predicting when the moon will be visible in the night sky.


What do you call the moon when the whole disc is visible from earth?
