Burntcoat Head, Nova Scotia flow back out. Each day the tides times will change approximately by one hour. The reason why the tides fills and empties the Bay of Fundy each day is due to gravitational pull of the moon and the sun on the earth, as well as earths rotation. Spring tides happen twice a month when the sun, moon, and earth are aligned. During this alignment the tides rise higher than average. Neap tides occur during the first and third quarter moon. During this time the high tides heights are lower than average. At low tide the ocean floor becomes exposed allowing
Jim Berkland G" system: 1) "the gravity gradient, or the forces exacted on the Earth by the gravitational pull of the Sun and the Moon." 2) "Gone Gatos" (missing cats) as indicated by advertisements in several newspapers. 3) "Geyser Gaps", seen as irregularities in the behavior of a geyser in the Napa Valley. Berkland's method has been said to also involve "a hodge-podge of factors". McClellan provides the most detailed description. Berkland starts with two lunar syzygies each month where the Sun, Moon, and Earth are aligned (corresponding to the new Moon and full Moon). He then sets a "seismic window" eight
