describe the appearance of the moon and its position during each phase:
• new moon:
• waxing crescent moon:
• first quarter moon:
• gibbous moon:
• full moon:
• waning gibbous moon:
• third quarter moon:
• waning crescent moon:

The new Moon appears during a period when the earth, the Moon,  and the Sun are all in a single line. Since the Moon is in between the Sun ad the Earth , the side of the Moon that directly facing the Earth is dark.

During full Moon, the three bodies  are also approximately in a line, but  the moon at this stage is on the other side of earth, so the Sun lights up the the section of the earth facing it.

At first quarter and last quarter, the Moon is located at a position perpendicular to a line between Earth and the Sun. one section of the moon is dark while the other will be brightened

Crescent refers to phases where the less than half of the moon is illuminated while gibbous is the phase where  more than half of the moon is illuminated.

After the new Moon phase, The waxing crescent is visible due to exposure some reflected sunlight rays . The lunar crescent continue to grow until first-quarter Moon. As the right section of the Moon extend to more than half of the Moon's face, the Moon becomes waxing gibbous.

Then, right after the full Moon, the right section begins to reduce again to make a waning gibbous and which then turn into a third-quarter Moon. The exposure to sunlight continues to lessen until the moon is a waning crescent and then a new Moon. The full cycle is carried out in  29.5 days.
