Moon phases depend on the position of both the Sun and Moon with respect to the Earth. The 4 primary phases of the Moon are: new, first quarter, full and third quarter.
A full moon is when the Moon is opposite of the Earth, relative to the Sun. The new moon is when the Moon is on the same side of the Earth as the Sun. Quarter moons are on either side of the Earth, 90 degrees from the position of full or new moons. Spring tides only happen when the Moon, Earth, and Sun are lined up.he new moon is when the Moon is on the same side of the Earth as the Sun.
