Astronomical Info

Tides are created becasue the earth and moon are attracted to each other, just like magnets are attracted to each other. The moon tries to pull at anything on earth to bring it closer. But, the earth is able to hold onto everything except the water. Since the water is always moving, the earth cannot hold onto it, and the moon is able to pull at it. Each day, there are two high tides and two low tides. The ocean is constantly moving from high tide to low tides, and then back to high tide. Usually it takes about 12 hours and 25 minutes between the two high tides. There are different types of tides.
