it when the moon is so dark
Spring tides are caused by new and full moons. Neap tides are caused by 1st and 3rd quarter moons.
The phases of the moon are not affected by solstice dates or equinox dates, they are caused by the sun shining on it at different angles while the moon is orbiting the Earth and new and full moons rarely coincide with "summer solstice" dates.
The moon's so-called "quarter" phases occur a quarter of a month (i.e. a week) before and after the New Moon. On each of those occasions, the moon appears half-full.
During the period that the moon's phases are changing from new to full, the moon is waxing. This means that the illuminated portion of the moon as seen from Earth is increasing. It starts with the new moon, where the moon is not visible, and progresses to the first quarter, then to the gibbous phase, and finally to the full moon. This sequence reflects the moon's orbit around Earth and the changing angles of sunlight illuminating its surface.
The moon phases from a new moon to a full moon is known as waxing. The moon phases from full moon to the next new moon is waning.
When the Sun, Earth and Moon are nearly lined up, the Sun and Moon's gravitational effects on tides are amplified slightly, causing higher-than-average 'spring tides". This happens at the new and full moon phases. When the Moon is at right angles to the Sun-Earth line, at the first and third quarter moon phases, we have lower-than-average "neap" tides.
When the term wane is used for the moon, it relates to the moon's phases. There are eight phases, the new moon, the full moon, 1st quarter, 3rd quarter, waning gibbous, waning crescent, waxing gibbous and waxing crescent. In your case, a wane moon means that it is getting smaller. A waxing moon or crescent means that it is getting bigger.
Yes, it does in deed have full moons and new moons. One or the other appears every 14.77 days.
"Spring" tides, which are a little higher than average, occur at new moons and full moons. "Neap" tides, a little lower than average, occur at the quarter moon phases.
During the new and full moons, the gravitational pull of the Moon and Sun align, causing higher high tides (spring tides) and lower low tides (neap tides). This alignment results in more extreme tidal fluctuations than during other phases of the moon.
Both Phobos and Deimos, the two moons of Mars, go through phases similar to our Moon. As they orbit Mars, their illumination changes until reach full moon phase with the entire disk visible, then waning to a new moon phase where they are not visible at all. These phases are caused by the changing relative positions of the Sun, moon, and Mars.
Well, Snookie has to shift her weight from time to time. She can't just stand there with her legs locked all day long!! The full moon is when she has her legs locked. The new moon is when she is lying down to get a spray tan. The Half moons are when she is shifting her weight from side to side, and the quarter (crecent) moons are the process of shifting her 532 pound body.
