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
Orbit of the Moon moves in its orbit around the common centre of gravity. The Sun's gravitational effect on the Moon is more than twice that of Earth's on the Moon; consequently, the Moon's trajectory is always convex (as seen when looking Sunward at the entire Sun–Earth–Moon system from a great distance outside Earth–Moon solar orbit), and is nowhere concave (from the same perspective) or looped. That is, the region enclosed by the Moon's orbit of the Sun is a convex set. Orbit of the Moon The Moon orbits Earth in the prograde direction and completes one revolution relative to the stars in about
