The Sun also exercises a gravitational attraction on the earth, which causes a secondary, less powerful, tidal effect (solar tide).Īpproximately twice a month, the sun, moon and earth will more or less align to form either a full moon or a new moon.

This in turn means that the time between a high tide and a low tide (and vice versa) is, on average, six hours and 13 minutes. Since the effect of the moon is the same when it’s straight “above” us as when it’s straight “underneath” us, one tide cycle (from high to high, or low to low) takes half that time: about 12 hours and 26 minutes. ( Kudos to Gord Steadman for providing the proper wording) where from a fixed point on earth the moon appears in the same position in the sky as a day earlier). It’s the combination of the speed at which the earth rotates on its own axis (once in 24 hours), and the speed at which the moon revolves around the earth (in 27.3 days), that dictate the time it takes to go from high to low tide.īecause the moon orbits in the same direction the earth rotates around its axis, it takes a little more than a day-24 hours and 53 minutes-for the earth to fully rotate in relation to the moon (i.e. These bulges are what we refer to as high tide.Īs the moon revolves around the earth the bulges shift with it causing a shift in the water level. They are the periodic rise and fall of the earth’s bodies of open water, and are a result of the gravitational pull of the moon and sun on the earth, as well as the perpetual spinning rotation of the earth itself.īy far the largest influence is the gravitational effect of the moon as it pulls the water toward itself, making a bulge on the surface of the ocean at the side of the moon (lunar tide).Īt the same time, the centrifugal force (caused by the spinning of the Earth-Moon system) acting on the water particles at earth’s surface opposite the moon,creates a second bulge.
Tides are considered the heartbeat of our planet’s oceans. The red sandstone and volcanic rock have been worn away to reveal fossils from over 300 million years ago. The effect of the world’s highest tides on the Bay’s shores has created dramatic cliffs and awesome sea stacks. This highly productive, rich and diverse natural ecosystem has shaped the environment, the economy and the culture of the Fundy region. The immense energy of the tides stir up nutrients from the ocean floor, the mud flats and salt water marshes, providing an abundance of food for the birds, whales, fish and bottom dwellers that visit or call Fundy home. The force created by these mighty waters is equal to 8000 locomotives or 25 million horses at the Minas Channel. The height of the tide difference ranges from 3.5 meters (11ft) along the southwest shore of Nova Scotia and steadily increases as the flood waters travel up the 280 km (174 miles) of shoreline to the head of the Bay where, in the Minas Basin, the height of the tide can reach an incredible 16 meters (53ft). The Bay of Fundy has the highest tides in the world, and those enormous tides alone make that the Bay of Fundy is one of the world’s greatest natural wonders.
