| The four major oceans | Indian, Atlantic, Pacific and Artic |
| Pagaea | one giant land mass 245 million year ago |
| Panthalassa | acient ocean |
| Layers of the ocean according to temperature differences | Thermocline, deep zone and surface zone |
| Warm top layer of ocean water, sun heats tom 100 meters of this zone, extens 300 meters below the surface | surface zone |
| Thermocline | In this zone water temperatures drop with increasing depth faster than in the other zones |
| Deep zone | Water temperature is a chilling 2 Degrees C |
| Salinity | Measure of the amount of salt and other solids dissolve in water |
| largest dissolve solid in ocean water | chlorine |
| contentieal shelf | begins at shoreline and slopes towar open ocean, continues until the ocen floor begins |
| contenintal slope | begins at edge of continental shelp and continues down to the flattest part of the ocean floor. |

| Sonar | sound navigation ranging |
| Geostat | top-secreat military satellite, used to measure changes in ocean height. |
| Seasat | Satellite that measured ocean current speed and direction. |
| Plankton | organisms that float on the surface of the ocean |
| phytoplankton | plant like organisms at oceans surface |
| zooplankton | animal like organisms at oceans surface |
| Nekton | free swimming organisms, whales, fish, sea lions and dolphins |

| intertidal zone | shallowest benthic zone, located between high and low tide. |
| Sublittoral zone | between the intertial zone an bathyal zone, extens down 200 meters but most organisms live in less than 100 meters of water depth where sunlight is able to reach. |
| Bathyl zone | Right above the abyssal zone, 200-4000 meters deep, animals include sponges, sea stars, octopuses and brachiopods |
| Hadal zone | deepest bentheic zone |
| abyssal zone | contains black smokers, worms, sea cucumbers and crabs and no plants |
