The only movement that really matters is the Moon orbiting the Earth.
The Sun shines, and sunlight strikes the Moon. The light bounces OFF of the Moon in all directions.
We stand here on Earth watching the Moon go around the Earth. Some of the reflected sunlight comes back to Earth. As the Moon goes around the Earth, we see that it is daytime on some parts of the Moon, and night on the rest.
The two phases of the moon that cause the strongest tides are the new moon and the full moon. During these phases, the sun, moon, and Earth are aligned, leading to higher high tides and lower low tides, known as spring tides. This alignment increases the gravitational pull on Earth's waters, resulting in more extreme tidal ranges.
The two motions that cause the Moon to show a complete cycle of phases each month are its orbit around the Earth and the Earth's rotation on its axis. As the Moon orbits the Earth, the angle between the Earth, Moon, and Sun changes, resulting in the various phases of the Moon. Simultaneously, the Earth's rotation allows us in New York State to observe these phases over the course of the month as the Moon rises and sets at different times. Together, these motions create the full lunar cycle we see each month.

The earth experiences spring tides when the moon is in the new moon phase and the full moon phase. During these times, the gravitational forces of the sun and the moon align, creating higher than normal tides.
The two phases during which the moon appears almost full but not quite are the Waxing Gibbous and Waning Gibbous phases. In the Waxing Gibbous phase, the moon is transitioning from the First Quarter to Full Moon, showcasing more than half of its surface illuminated. Conversely, during the Waning Gibbous phase, the moon is moving from Full Moon to Last Quarter, still displaying a significant portion of its surface lit but gradually decreasing.
The moon has many different phases that it goes through multiple times throughout the year. The two factors that cause these phases are its position in relation to the Earth's shadow. The second one is the position of the sun in relation to the moon.
There are 8 phases of Earth's Moon: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, and Waning Crescent.

The two phases of a waxing Moon are the first quarter and gibbous. During the first quarter, half of the Moon is illuminated and appears as a half-circle in the sky. During the gibbous phase, more than half but not yet fully illuminated, the Moon appears as a large, slightly bulging shape.

Earthshine occurs during the phases of the Moon known as "new moon" and "first quarter moon." During these phases, sunlight illuminates the Earth, which in turn reflects some light back towards the Moon, creating the phenomenon known as earthshine.
The two phases during which the moon appears only as a tiny sliver are the Waxing Crescent and Waning Crescent phases. In the Waxing Crescent phase, the moon is transitioning from the New Moon to the First Quarter, while in the Waning Crescent phase, it is moving from the Last Quarter back to the New Moon. During both phases, only a small portion of the moon's surface is illuminated by sunlight, creating the slender crescent shape.
Actually it is not the rotation of the earth but the orbit of the moon around the earth that causes the phases of the moon. The moon's relationship in it's orbit with regard to the sun is what causes the phases to change. When the moon is between the earth and the sun, it is in a "new moon" phase because the only side of the moon that is lit with sunshine is the far side or the unseen side of the moon. When the earth is between the sun and the moon, the moon is at "full moon" phase. In between these two extremes gives us the 1st quarter and the 3rd quarter phases.
First Quarter or Third Quarter.
The two phases during which the moon appears as only a tiny sliver are the waxing crescent and the waning crescent phases. In the waxing crescent phase, the moon is transitioning from new moon to first quarter, gradually becoming more illuminated. Conversely, in the waning crescent phase, it is moving from the last quarter back to the new moon, with only a small portion of the moon's surface visible. During both phases, the illuminated part of the moon appears as a thin crescent shape.
The earth experiences spring tides when the moon is in the new moon phase and the full moon phase. During these times, the gravitational forces of the sun and the moon align, creating higher than normal tides.
