There is a tidal bulge toward the moon on the side of the earth facing the moon at any given moment, because that's where the gravitational pull of the moon is greatest.. There is also a tidal bulge on the opposite side of the earth, away from the moon, because that's where the gravitational pull of the moon is least. Water drawn into these tidal bulges is of course drawn from water in other areas - the "sides" of the earth so to speak, halfway between the two tidal bulges. As the earth makes one rotation on its axis, any given section of land passes through first one tidal bulge, then the other, with the tidal deficit areas coming in between. Hence, two high tides and two low tides per day.
