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 Waves.

Approx. 6 1/2 hours apart. What causes TIDES?. Description of Waves. 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. 6. th. Grade Earth Science. Currents. A current is a large stream of water that flows through the ocean. . Two types of currents. Surface Currents Deep Currents. 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.
