TIDES

The ebb and flow of the tides may be something T we take for granted, but without gravity, the tides wouldn't exist. In a 24-hour period. there are two high tides and two low tides. These occur every day although the times vary due to something called slack the period of time in between tides when water is still How long this slack period lasts depends on the moon's gravitational pull. Even though the moon's gravitational pull is only one ten-millionth that of Earth's, it combines with Earth's centrifugal force to create tides. (The sun also has an effect on tides, but it's not nearly as strong as the moon's effect) The strength of the moon's effect on tides is based on the moon's phase (whether it's a full moon or a new moon) and distances between Earth the sun, and the moon in their orbits Tides are at their maximum when Earth, the sun, and the moon are aligned. The Bay of Fundy in Nova Scotia boasts the highest tides in the world, with a range of 44.6 feet between high tide and low tide.
