Have you ever been at a beach where at low tide you have to walk way out in the water just to get in up to your knees? Yet there are some places where you can hardly tell the difference between high and low tide.

The reason for this has nothing to do with the moon. Tides are caused by gravitation. Just as the earth pulls on the moon, so the moon attracts or pulls on the earth, but with much less force. The pull of the moon upon the earth draws the ocean waters nearest to it toward the moon as a broad swell, or wave. This produces high tide.
