PPT-Wind and Ocean 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. Vocabulary. Ocean Current. Coriolis Effect. Rip Current. Upwelling. Major Ocean Currents. An . Ocean Current. is a large volume of water flowing in a certain direction.. Wind-driven currents are called surface currents.. s. Warm. . currents flow . away. from the . equator.. Cold. currents flow . toward. the . equator.. Ocean Currents. Sun. Wind. Coriolis. Effect. Gravity. Factors Influencing Currents. Energy from the Sun heats the water.. Submarine Relief. Hydrosphere. 71% of total surface of the earth. Term ‘sea’ used for water bodies close to continental margins. Great mass of water surrounding oceans called ‘oceans’. Submarine relief. Currents. 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. . 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. 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. 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. How do different currents form. What is upwelling. What do ocean currents transfer. Predict. T F. Ocean currents are always cold. C. ontinents affect the direction of currents. Currents only flow near the surface of the ocean. This book belongs to: Ms. Ashmead Mississippi State Objective: 4c. Describe the causes and effects of heat transfer as it relates to the circulation of ocean currents, atmospheric movement, and global wind patterns (e.g., trade winds and the jet stream). Provide examples of how these global patterns can affect local weather. salinity stratification. fresh/saltwater interface. upwelling. tides. PUBLIC. recreation, . tourism, fishing. interest groups (divers, surfers). drinking water. treated-wastewater release. 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. By: Sean Meisner, Amanda Onwukwe, Arrian Bolden Pd:2nd. What Is Wind?. Wind: Is air moving across the surface of the Earth. Wind occurs because sunlight heats the earth’s atmosphere and surface unevenly.. April 19 and 20, 2018. Mark A. Bourassa. 1.
