Water is the main source of all life on earth. It is the universal solvent from a chemical perspective, and is the reason why we are here. It has a complex cycle that essentially defines earth's climate and is the most common liquid on the planet. With out it, we would not be here, and earth most likely wouldn't be either. Even if it was, it would be nothing like what it is today.
Erosion
It Effects The earth?
It is not the gravitional effect ON the moon, but the gravitional effect OF the moon. The moon pulls on the earth, just as the earth pulls on the moon. The pull of the moon causes water to be drawn towards the moon, and forms a "bump" in the level of water. As the earth rotates below the water, the raised part of the water has the effect of making the water get deeper, then shallower. Those are the tides.
Water goes from the earth into the air because of the effect of the sun on the earth which causes warm air to rise.
Moving water effects the earth materials by slowly eroding or breaking it down.

The moon's gravity attracts the water.
