PPT-Chapter 11 Tides

Tides Tides Are the Longest of All Ocean Waves hence they are Long waves Tides Are Forced Waves Formed by Gravity and Inertia They are responsible for the rise and fall in sea level Tides . They follow a cycle that coincides with the 24 hour 50 minute lunar day the time it takes earth to make one complete rotation relative to the moon Along Americas Atlantic Coast two high and low tides occur daily with relatively little difference bet Chapter Chapter 11 11 Between the Tides What is the intertidal zone?
