Physical Oceanography

1. currents,flowing fluid that is moving because there is a temperature or density difference within the material.
4. or gyrate
9. movement of deep, cold, and nutrient-rich water to the surface
11. amount of salt in water
12. a raised mass of water on the surface of water caused by the wind or by tides making the surface of the water rise and fall
14. Pacific Garbage Patch, is a gyre of marine debris particles in the central North Pacific Ocean
15. ice,frozen ocean water
16. current,result from differences in water density. These currents occur when cold, dense water at the poles sinks

2. circulation, As ocean water freezes at the poles it concentrates salt, and the colder, denser water sinks.
3. ________ are driven by wind, water density differences, and tides
5. Salinity, temperature and depth all affect the _______ of seawater.
6. tide,a tide just after a new or full moon, when there is the greatest difference between tides
7. Stream,A warm ocean current that flows from the Gulf of Mexico northward through the Atlantic Ocean
8. tide,a tide just after the first or third quarters of the moon when there is the least difference between tides
10. regular rise and fall of the ocean's surface influenced by the moon's gravity pulling on earth
13. current,A horizontal movement of ocean water that is caused by wind, occurs at the ocean's surface
