BY DIFFERENTIALS A handicap differential is the differ ence between the adjusted gross score and the USGA Course Rating multiplying the difference by 113 dividing the result ing figure by the USGA Slope Rating and rounding off to the nearest tenth T 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.. 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. What is “pressure”, what is “density”, and how do we measure them?. Who contributed to our current ideas and theories about pressure?. Where can we see pressure measured on a daily basis?. Important Questions. 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. 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. William M. White, Cornell University, USA. Creation of Oceanic Crust. Oceanic crust is produced as magmas rise from the mantle below and ‘freeze’ to fill the gap as lithospheric plates spread apart.. 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. PES 1000 – Physics in Everyday Life. Macroscopic vs. Microscopic Quantities. We have been studying the motion of regular-sized (. macroscopic. ) objects. We know these objects are made up of countless atoms and molecules (.
