Apart from the high tide and low tide,there are spring tides and neap tides.
When the tidal range(the difference in height between a high tide and a low tide) is maximum,then it is called a spring tide.This happens during full noon or new moon when the sun ,moon and earth are in the same line.In this situation, the tidal forces due to the sun reinforces those of the moon.
Neap tide occurs when the above mentioned tidal range is minimum.This happens when the moon is at first quarter or third quarter.In this situation,the sun and the moon are separated by 90 degrees when viewed from the earth and the forces due to the sun partially cancels those of the moon.
There are seven day interval between spring tides and neap tides.

Great questions. I'm not an astronomer, but I think I can take a guess at some of these. 1. No - reflected moonlight on Earth is barely enough to see by - it would show up very faintly if reflected off another body. 2-5. Imagine two ping pong balls circling a drain. They might be in sync, or they might not. Even if they are the same size, they do not have to go at the same speed, or in the same shape. Then imagine standing on one side of the room and shining a bright light. If you are standing in the drain, each one will appear as a different shape. If the two are close together, they will have a similar shape - if they are on opposite sides of you, they will look like mirror images. So for 2-5: yes, yes, maybe, not necessarily. 6-8. We depend on the moon for the magnetic field to protect the earth from all sorts of space nasties and keep the oceans from evaporating. The moons gravity is what keeps the earths core molten, which in turn creates the field. If we didnt have the moon, we'd have a lot more to worry about than weather. If there were two moons of exactly equal size on exactly opposite sides of earth, I imagine they could counter each other out, sparing the earth the gravitational pull that heats up the center. Again, the result would be that Earth would turn into Mars. If they are not precisely equal, they could exert a lot more or somewhat less pull, which would result in things like much larger tides and extreme - probably unsurvivable weather. As for the oceans, it is the motion of the core that allows the continents to move. Without that, erosion would wear the entire surface down to a basketball, which would be covered by a shallow ocean. More would allow for more tectonic activity, which would make it lumpier. So 6-8: heck yes, death - horrible death!, more moon=more mountains. Thanks for a great question!

Aside from regular tides, the spring tide occurs when the Sun, Moon, and Earth are in a straight line, and is higher than average. The neap (pronounced "nip") tide occurs when the Moon, Earth, and Sun form a right angle (i.e., the Moon is off to one side of the Earth), and is lower than usual.

I know of only a couple. There is Tide Regular, Tide with Bleach, All Color Tide and I think there is a Tide for hand washables, like unmentionables. Good luck!
