PPT-Ocean Waves and Tides

Waves A Wave is a rhythmic movement that carries energy through matter or space In oceans waves move through seawater Waves Caused by Wind Earthquakes Gravitational force of the Moon and Sun. 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 Rockefeller Jr Memorial PKWY Big Hole NB Cowpens NB Fort Donelson NB Fort Necessity NB Moores Creek NB Petersburg NB Stones River NB Tupelo NB Wilsons Creek NB Kennesaw Mountain NBP Richmond NBP Brices Cross Roads NBS Chickamauga and Chattanooga NMP High or Low - What Causes Tides?.

A wave is the rhythmic movement that carries energy through space or . matter. Waves are generated by wind flowing over the water . surface. As a wave passes, water moves up and down in a circular pattern – returning to its original position. Mean Low Tide versus Mean Lower Low Water. And the winner is……….!. Measuring Water Depths.

Objectives. Define terms used to describe tides. List and define the forces that cause tides. Describe tide measurements and the use of harmonic tidal constituents to predict tides. Section 19.3. Daily Question 1/6/15. In your daily question book write down at least three things you know about the moon. If you know more, please write them down as well.. Motions of the Moon. The moon travels through space in two ways:. Created by Winds. Coriolis Effect- The shifting of ocean currents and surface winds from their expected paths caused by the rotation of the earth. Gulf Steam – ocean current in the northern Atlantic ocean, brings warm water from Africa to the Americas. Datums. plus some NOS Resources. Marti . Ikehara. , Geodetic Advisor. NOAA’s NGS, Sacramento.

The tides result from the rotation of Earth on its axis as gravity . from the moon and the sun pull on Earth and its water. Think . What are tides?. Tides are the daily changes in the level of ocean water.. What causes tides?. Tides are caused by the difference in the gravitational force of the sun and the moon.. What is tidal force?. TidesThe tides are the rising and falling of the ocean surface as a result of the gravitational pullof the moon and the Sunon the earthThe Moon plays a bigger role than the Sun because it is closerEff Energy is moving, not water. orbital motion. energy is transferred via circular motions. water (and gull) return to original position. the wave form moves forward. Motion decreases with depth. At. a depth of ½ of the wavelength, the motion is not significant..
