PPT-Currents and Wind

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 . 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. 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.. Waves and Currents. Formation of Waves. Travelling Waves. Anatomy of Waves. Forces Generating Waves are Different. Wave type Period Disturbing force Restoring force. Capillary <0.1 sec Wind Surface tension. 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. 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. 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. 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. 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. Ocean Currents?. Chapter 9. First ….a key concept to keep in mind:. Winds. are named from the direction in which they are coming….. for example: A Southerly – is a wind coming from the south . 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.. Ocean Current Layers. Surface Currents. . – . top . 10% of the ocean; upper 400 m. Deep Currents . – lower 90% of the ocean. Properties . of . Ocean . Water . How they impact ocean currents. Temperature.
