| salinity | a measure of the amount of dissolved salts in a given amount of liquid |
| ocean currents | the movement of ocean water that follows a regular pattern |
| surface currents | the horizontal movement of ocean water that is caused by wind and that occurs near the ocean's surface |
| deep current | a streamlike movement of ocean water far below the surface |
| Coriolis effect | the apparent curving path of a moving object from an otherwise straight path due to the Earth's rotation |
| deep current | a streamlike movement of ocean water far below the surface |
| upwelling | the movement of deep, cold, and nutrient-rich water to the surface |
| El Nino | a change in the water temperature in the Pacific Ocean that produces a warm current |
| crest | the highest point of a wave |
| trough | the lowest point of a wave |
| wavelength | the distance between two adjacent wave crests or wave troughs |
| wave period | the time between the passage of two wave crests or troughs at a fixed point |
| breakers | where waves first begin to tumble downward or break |
| surf | The area between the breaker zone and the shore |
| tides | the periodic rise and fall of the water level in the oceans and other large bodies of water |
| tidal range | the difference in levels of ocean water at high tide and low tide |
| spring tide | a tide of increased range that occurs two times a month, at new and full moon |
| neap tide | tide of minimum range that occurs during the first and third quarters of the moon |
| La Nina | a change in the eastern Pacific Ocean in which the surface water temperature becomes unusually cool |
| longshore currents | a water current that travels near and parallel to the shoreline |
| storm surge | a local rise is sea level near the shore that is caused by strong winds from a storm |
| tsunamis | a giant ocean wave that forms after a volcanic eruption, submarine earthquake, or landslide |
