phases of the moon Flashcards
new moon
the side of the moon facing the Earth is not illuminated. The moon is up throughout the day, and down throughout the night. For these reasons we cannot see the moon during this phase.
phases
the different shapes of the moon you see from Earth caused by the motions of the moon around Earth.
waxing crecent
during this phase, part of the moon is beginning to show. This lunar sliver can be seen each evening for a few minutes just after sunset. We say that the moon is “waxing” because each night a little bit more is visible for a little bit longer.
first quarter
during first quarter, 1/2 of the moon is visible for the first half of the evening, and then goes down, leaving the sky very dark.
waxing gibbous
when most of the moon is visible we say it is a gibbous moon. Observers can see all but a little sliver of the moon. During this phase, the moon remains in the sky most of the night.
