Essential Question: What causes tides in the oceans?

Ocean Waves and Tides Waves A Wave is a rhythmic movement that carries energy through matter or space. A Wave is a rhythmic movement that carries energy.

Tides Section What are tides? The daily rise and fall of Earth’s waters on its coastline High Tide – when water reaches its highest point on shore.

The word "tides" is a generic term used to define the alternating rise and fall in sea level with respect to the land, produced by the gravitational attraction.

The ocean is divided into zones with their own combination of challenges and resources

Add neritic and hadal zones

What are the challenges of living in the intertidal zone?

ChallengeOrganismRelative adaptation

The tide comes in Mont Saint Michel Normandy, France Population: 44 Visitors per year: 3 million

The tide goes out arctic tide

Higher high tides + lower low tides = greater tidal range

Higher low tides + lower high tides = smaller tidal range

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

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)

True tidal waves: tidal borestidal bores

Long narrowing waterway Bay of Fundy

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
