Document Summary
The motion of the ocean and the transfer of energy. Tides: they govern how life is distributed on the coast, their predictable nature are fundamental for navigation, you can surf them. Take home points: semi-diurnal tide: 2 high tides and 2 low tides, the time between successive high tides is ~12 hours and 25 mins (this is the tidal. Period: the timing of the tides can vary considerably along the ne coast, yet all the towns experience semi-diurnal tides with a period of 12 hours and 25 minutes. Primary causes for the tides: the gravitational pull of the moon. Can explain one tide a day: the rotating earth-moon system (centrifugal force) The effects of inertia resulting in an apparent outward force away from the center of rotation. Tides are caused by an imbalance between the centripetal and gravitational forces acting on earth.
