Answer:
Step-by-step explanation:
Spring and neap tides are both caused by the alignment of the moon. Spring tides are tides that occur when the moon is aligned with the earth and the sun, allowing the gravitational pull from the moon and the sun to reinforce each other and make an overall higher tide that is paralell to the alignment of the earth, moon, and sun. During a spring tide the moon is either a new moon or a full moon. During a neap tide the moon is half full, either waxing or waning, and the tidal bulge is perpendicular to the sun win the moon 's alignment to the sun is perpendicular from earth's point of view.
