| A | B |
|---|
| waves | pulses of energy |
| neap | lower than normal low tides |
| spring | higher than normal high tides |
| antarctic bottom water | coldest, densest water |
| evaporation | affects density in warm climates |
| counterclockwise | direction of currents south of equator |
| clockwise | direction of currents north of equator |
| turbity currents | dense water masses of sand, silt |
| wind | most common source of wave energy |
| speed, time, distance | affect height of surface waves |
| circular | pattern of motion for water molecules |
| tsunamis | "tidal wave" |
| earthquakes, volcanoes | cause tsunamis |
| crest | highest part of a wave |
| trough | lowest part of a wave |
| wavelength | distance between two wave crests |
| current | river in the ocean |
| rotation | causes current pattern |
| warm | describes current coming from equator |
| cold | describes current coming from poles |
| rip | currents that carry you away from shore |
| longshore | currents that move parallel to shore |
| phytoplankton | basic food in the oceans |
| moon | causes tides |
