I am not in school. I am in a nursing home and cannot get to the library so the net is my only way of learing. My question is why are some tides higher than others? Thank you if you can answer me.
Answer 1:

One of our researchers has provided the address to GREAT website o you to check out. It tells all about tides!

Answer 2:

First off, tides are caused by the moon and, to a lesser extent, the sun exerting a gravitational force on the earth. Since the gravitational force decreases as 1/(distance squared), the surface of the earth nearest the sun or moon is pulled away from the center of the earth a little bit. Also, the far side of the earth lags a little bit. The effect of this is that the earth has bulges that point towards and away from the moon and the sun. As the earth rotates, different parts of the planet experience these bulges and thus tides. Tides are very complicated, but, in general, they change as the moon rotates around the earth and thus changes its position with respect to the sun.
