PPT-Currents, Tides, Waves Surface currents – move horizontally or parallel to the earth’s

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. 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. Section 3: Currents, Waves, and Tides. Earth Science. Mr. Margetan. . Ocean Currents. Surface Currents – Movement of water on the surface, primarily caused by winds. Ocean Currents. Longshore. Currents – Currents which run parallel to the shoreline due to energy released from waves. http. ://oceanexplorer.noaa.gov/edu/learning/player/lesson08.. html. . . I. .
