The moon goes through several phases, from new to full and back to new again.
It varies
it is a moon phase
As seen from the moon, the Earth is a brighter source of light than the moon is as seen from the Earth. This also depends upon the phase of the Earth, just as the brightness of the moon varies by phase. A full moon and a full Earth are in the brightest phase.
It means that the phase is ending.
New Moon.
The new moon is the phase of the moon when only the side of the moon away from the earth is lit, so the side facing earth is in near total darkness. The moon is very difficult to see during this phase.
The time in which the whole face of the moon is illuminated - when the moon is on the opposite side of the Earth as the sun.
The Moon's phase is New Moon.
first quarter of the moon is second phase of the moon. it means that the shape of the moon is growing to the waxing gibbous.
The phase of the Moon varies each day. You posted this question on November 24, 2010. On that day, the Moon was waning gibbous with 89% of the Moon's visible disk illuminated.
How much of it is visible from earth, ie half moon, full moon etc. These are the phases
Full Moon -> Waxing gibbous phase -> First quarter phase -> Waxing crescent phase -> New moon -> Waning crescent phase -> Last quarter phase -> Wanning gibbous phase -> Full Moon
