PPT-Ocean Currents Guided Notes

What is a current 1 An Ocean Current is a directed continuous movement of ocean water generated by various forces 2 Currents are caused by various factors Temperature Different salinity levels. 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 Early ocean studies. For much of human history, knowledge of the ocean and its currents was not recorded for many reasons - most sailors could not write and information was passed orally.. European nations began systematic ocean explorations but kept information secret between the 15. The Earth is Spinning…. Because Earth spins, winds and water appear to be deflected in a curved motion. This is called the Coriolis Effect. Which way do things. not connected to . Earth get deflected . Name. . the three major processes in the water cycle.. Describe. . the properties of ocean water.. Describe. . the two types of ocean currents.. Explain. how the ocean regulates Earth’s temperature.. Wind-driven surface currents. Figure 7-4. Ocean Circulation Animation. Ocean Currents. Ocean currents- are stream-like movements of water. Ocean currents affect our weather and climate. 2 Types:. 1) Surface Currents. Global winds. Ocean Currents . Local winds. Coriolis Effect. Because the Earth rotates, and consists of a mixture of land and sea, the . Coriolis Effect . exists. The . Coriolis Effect. is the movement of particles (such as air) to the right in the Northern Hemisphere. http. ://oceanexplorer.noaa.gov/edu/learning/player/lesson08.. html. . . I. . Ocean . currents = Stream like movements of water. A. Surface currents. = occur near or at the surface of the ocean. Can reach 100 m deep or deeper. Transport . heat. Equator to poles. Transport nutrients and organisms. Influences weather and climate. Influences commerce. Surface . Currents. The upper 400 meters of the ocean (10%).. Deep Water 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. Earth/Space. S.W.B.A.T.. Explain how winds and the . Coriolis. effect influence surface currents. Discuss the temperatures of coastal waters. Describe density currents and how they affect Earth. Surface Currents. Highways in the Sea. What forces are responsible for currents?. Wind. : transfers energy through friction on surface; causes currents and waves. Sea level. : steeper slope=greater pressure gradient=drives a larger, faster current. For much of human history, knowledge of the ocean and its currents was not recorded for many reasons - most sailors could not write and information was passed orally.. European nations began systematic ocean explorations but kept information secret between the 15. Chapter 14. Page 364 – 387. Currents. Imagine that you are stranded on a desert island. You stuff a distress message into a bottle & throw it into the ocean, hoping it will find its way to someone who will send help. . Conclusions Up Front:. Mid-Atlantic is home to the most advanced observing systems in the world. Much can be leveraged to support the Blue Ocean Economy. Well defined process to fill gaps. Greatest need is not for new technologies .
