Tide
The predictable, regular rising and lowering of water in some areas due to the pull of the sun and the moon. Tidal changes can happen approximately every 6 or 12 hours depending on the region. To find out the time and water levels of different tides, you can use tide tables for your area. The period of high water level is known as high tide and the period of low water level is known as low tide. In the Bay of Fundy, the tidal range exceeds 40 feet (13 meters.)
