The different phases have different effects on the weather and sometimes people. Many people say that when there is a full moon people become more stressed and if you are given a lot of work you will become frustrated.
Tides are created because the Earth and the moon are really attracted to each other. So the moon will do anything to pull the Earth closer. The Earth holds on to everything but water. So the moon pulls the water towards itself and this creates high tides and low tides.
