PPT-EXERCISE SIMMERING CURRENTS 2014/15

19 INTRODUCTION South Asia is unique with its myriad of problems Home to 3 nuclear powers but also to the worlds poorest One fifth of humanity 16 billion live here with a GDP of US 24 trillion . 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 . 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. . 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. Emma Bunce and Stan Cowley.

The field-aligned currents that flow between the ionosphere and magnetosphere in planetary . 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. 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. What do ocean currents transfer. Predict. T F. Ocean currents are always cold. C. ontinents affect the direction of currents.
