Tides: the regular rise and fall of ocean water caused by gravity Earth has 2 Tidal bulges: (high tides that move as the moon revolves) -in 25 hours Earth rotates through the two tidal bulges to experience two high and two low tides each day. SPRING TIDES are the strongest with the highest high and the lowest low tides. Occur during a Full and New moon when the sun Earth and moon line up in a straight line (180◦) NEAP TIDES are the weakest with less noticeable high and low tides. Occur during a half moon phases when the sun Earth and moon make a right angle (90◦)
