Phases And Eclipses Vocabulary

Question 0

New moon

Answer 0

The side of the moon facing the Earth is not illuminated. Additionally, the moon is up through out the day, and down through out the night. For these reasons we can not see the moon during this phase.

Question 1

Phases

Answer 1

The different shapes of the moon you see from Earth caused by the motions of the moon around Earth.

Question 2

Waxing crescent

Answer 2

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.

Question 3

First Quarter

Answer 3

During the 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.

Question 4

Waxing gibbous

Answer 4

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.

Question 5

Full Moon

Answer 5

When we can observe the entire face of the moon, we can call it a full moon. A full moon will rise just as the evening beginning, and will set about the time morning is ushered in.

Question 6

Waning Gibbous

Answer 6

Like the Waxing Gibbous Moon, during this phase, we can see all but a sliver of the Moon. The difference is that instead of seeing more of the Moon each night, we begin to see less and less of the Moon each night. This is what the word “waning” means.

Question 7

third/last quarter

Answer 7

During a Last Quarter Moon we can see exactly 1/2 of the Moon’s lighted surface.

Question 8

Waning crescent

Answer 8

Finally, during the waning crescent Moon, observers on Earth can only see a small sliver of the Moon, and only just before morning. Each night less of the Moon is visible for less time.

Question 9
