Earthshine is the faint glow on the part of the moon that is shadowed. It is best seen during the waning and waxing crescent phases of 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.
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.

If you are referring to lunar phases, there are two phases in which the moon is not visible to the earth. In the New Moon and Dark Moon lunar phases, the moon is not visible to those on earth. See related links for more information.

Spring Tides occur during two phases, full and new moon. This is because the moon earth and sun are aligned during both of these phases. It is opposite during neap tide, in which the moon and sun meet at a right angle on earth, which means the moon during neap tide is at the first or third (last) quarter phase. Hope this helped! :)
Approximately two to three.... and they depend on the theoretical "starting point" phase. It takes about two weeks for the moon to go from "new" to "full". So, in one week the moon could go from "first quarter" to "waxing gibbous" to "full"
Spring tides occur during the full moon and new moon phases. During these times, the gravitational forces of the moon and the sun align, resulting in higher high tides and lower low tides. This alignment creates the greatest difference between high and low tides, leading to the phenomenon known as spring tides.

The four phases of the moon that appear to last 1 or 2 nights are the New Moon, First Quarter, Last Quarter, and Full Moon. The New Moon and Full Moon both occur for one night, while the First Quarter and Last Quarter phases can last for about one to two nights.
First Quarter or Third Quarter.
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.
The tides are mainly caused by the gravitational pull of the Moon on the Earth, and its effect on the water levels of the oceans.
