During any 24 hour period, the moon nearly completes one revolution around earth [apparent motion, not true motion]. Combined tidal forces cause a bulge in the earth's water at the location roughly below the moon and also at the part of the earth opposite that location. A scarcity of water occurs in the places roughly at 90 degrees to those locations. So as the earth moves through a day, it 'passes under' two high tides and two low tides.
