Key Point:The centrifugal force acting on
Earth's waters is NOT due to the Earth's rotation...but due to the rotation of the Earth-moon system around the barycenter....

Earth's Rotation -- brings different coastal areas into and out of the tidal bulge....
Moon's Revolution -- changes the location of the tidal bulge....
otherwise...the location experiencing high or low tide would take days to change
otherwise...high tides and low tides would always occur at the same time every day
