| Name the zones from closest to shore to the deep ocean. | littoral (surf to 30m), Neritic (above continental shelf to 60m), Oceanic |
| What type of bonds are water molecules? | Hydrogen bonds |
| density increases with decreases in temperature | Anomalous behavior |
| Dissolved inorganics, gases, and inorganic compounds make up this type of water. | Sea water |
| Oxygen Concentration vs Temperature | the higher the oxygen, the cooler the water |
| The pH of saltwater is typically around | 7.5-8.4 |
| Anthropogenic means... | caused by humans |
| What colors are absorbed by the ocean? (from closest to the surface to deep down) | red, yellow, green, blue |
| A rapid change in temperature occurs here | thermocline |

| _____ have permanent thermocline, ______ has no thermocline, and _____ has seasonal thermocline | tropics, polar, temperate |
| If nutrients are depleted in shallow water this limits ____. | photosynthesis |
| wind stress results in offshore movement of surface waters which are replaced by deeper, colder water | Coastal Upwelling |
| Equatorial Current and Equatorial Counter current run in opposite directions which causes surface waters to diverge and be replaced by deeper water | Equatorial Upwelling |
| produced by winds-- cold water sinking under warmer water | Coastal Downwelling |
| is a large system of circular ocean currents formed by global wind patterns and forces created by Earth's rotation | Ocean Gyres |
