Here's how it works:
* The moon's gravity is the primary driver of tides. It exerts a stronger gravitational pull on the Earth's oceans than the sun, even though the sun is much larger.
* During neap tides, the sun and moon are at right angles to each other relative to the Earth. This means the sun's gravitational pull is working against the moon's pull, effectively lessening the overall tidal force.
* The result is a weaker high tide and a weaker low tide, leading to a smaller difference between the two – a smaller tidal range.
In contrast, spring tides occur when the sun and moon align. Their combined gravitational pull creates a stronger tidal force, resulting in higher high tides and lower low tides, and therefore a larger tidal range.
So, to summarize:
* Neap tides: Sun and moon at right angles, smaller tidal range.
* Spring tides: Sun and moon aligned, larger tidal range.
