14 Higher high tides + lower low tides = greater tidal range

15 Higher low tides + lower high tides = smaller tidal range

16 Review the tide calendars of Narragansett Bay and come up with 5 pieces of information

20 An amphidromic point is a no tide point in the ocean. A tide wave crest comes into an ocean basin (a). The coriollis effect causes it to veer right (b). It cannot continue right because of interference by the land so it heads north © then westward (d)

28 Bay of Fundy: Largest Tidal Range 17 meters (53-55 ft.) tidal resonancetidal resonance resulting from a coincidence of timing: the time it takes a large wave to go from the mouth of the bay to the inner shore and back is practically the same as the time from one high tide to the next. time lapse
