| current | in geology, a horizontal movement of water in a well-defined pattern, such as a river or stream |
| surface current | a hroizontal movement of ocean water; caused by wind; occurs at or near the ocean's surface |
| Coriolis effect | the apparent curving of the path of a moving object from an otherwise straight path due to Earth's rotation |
| gyre | a huge circle of moving ocean water found above & below the equator |
| Gulf Stream | the swift, deep & warm Atlantic current that flows along the eastern coast of the US toward the north |
| deep current | a streamlike movement of ocean water far below the surface |
| wave | a periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium |
| wave period | the time required for 2 consecutive wave crests to pass a given point |
| fetch | the distance that wind blows across an area of the sea to generate waves |
| refraction | process by which ocean waves bend directly toward to coastline as they approach shallow water |
| tide | the periodic rise & fall of the water level in the oceans & other large bodies of water |
| tidal range | the difference in levels of ocean water at high tide & low tide |
| tidal oscillation | the slow, rocking motion of ocean water that occurs as the tidal bulges move around the ocean basins |
| tidal current | the movement of water toward & away from the coast as a result of the rise & fall of the tides |
