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. Vocabulary. Ocean Current. Coriolis Effect. Rip Current. Upwelling. Major Ocean Currents. An .

Ocean water contains streamlike movements of water called . ocean currents.. Currents can travel extremely far. In ancient times, currents were largely responsible for any human travel across the oceans. It is believed that currents carried the ancient Peruvians over 6,000 km across the south pacific to Polynesia. . Emma Bunce and Stan Cowley. University of Leicester, UK.

The field-aligned currents that flow between the ionosphere and magnetosphere in planetary . The water in the ocean moves in giant streams called currents.. Scientists place ocean currents into two major categories: surface currents and deep currents.. Surface . Currents. Ocean currents that occur at 328 feet deep or above. 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. Weather Patterns. Weather pattern’s are described as prolonged temperature changes over a specific area for example seasons.. Weather patterns can also be described as a period for which natural disasters are prevalent ex. Hurricane season, tornado season, blizzards. How do different currents form. What is upwelling.
