Here's why:
* Gravitational Pull: Both the Sun and Moon exert gravitational pull on Earth, affecting the oceans.
* Alignment: When the Sun, Earth, and Moon are aligned (during a new moon or full moon), their gravitational forces add up. This combined pull creates a stronger tidal bulge, resulting in higher high tides and lower low tides.
* Spring: The term "spring" in this context doesn't refer to the season. It comes from the Old English word "springen," meaning "to leap" or "to surge," reflecting the larger tidal range during these events.
