But where the edges lap at shorelines, the change in water level — or tidal range — is marked. In North Carolina, the variance is only a few feet; but along the funnel-shaped Bay of Fundy in Canada, the tide may vary as much as 50 feet from low to high. Tidal range is also affected by seasonal variations — such as atmospheric pressure, rain- fall and wind direction — and man-made alterations in certain harbors. higher high tide is commonly thought

At the first and third quarter, when the sun and moon form a right angle to the Earth, scant or "neap" tides occur. The tide-producing forces of the moon and sun cancel each other out, causing lower high tides and higher low Sun.
