Answer:
There are 6 phases of the moon:
New moon
Crescent
First quarter
Gibbous
Full
Third quarter
Explanation:
The Moon's visible face appears to be more or less illuminated over the course of the month. This is due to our changing view of the Moon's day and night side
The Moon can only pass through Earth's shadow during a single day of the month: Full Moon. At other times of the month, the Moon is far from Earth's shadow. So Earth's shadow plays no part in the cycle of the phases of the Moon.
