| Elements | Substances comprised of atoms of a single type that cannot be divided into other substances. |
| Hydrogen Bond (Weak) | Weak chemical bond formed between the electronegative oxygen atom of one water molecule and the electropositive hydrogen atom of another water molecule. |
| Hydrosphere | All of the waters of the Earth. |
| Hypoxia | A condition of low dissolved oxygen concentration in a body of water. |
| Keeling Curve | The graph that depicts the rise in atmospheric carbon dioxide. |
| Limiting Factors | Any factor that limits the productivity of autotrophs. |
| Macronutrients | The dissolved chemical substances in greatest demand by photosynthetic organisms. |
| Major Constituents | Those dissolved inorganic compounds in seawater whose concentration exceeds 1 part per million. |
| Micronutrients | Those dissolved substances required in small amounts by autotrophs. |
| Molecules | Substances composed of two or more atoms. |
| Oxygen Minium Zones | A region of the world ocean where the concentration of oxygen reaches a minimum at depth, caused by the biological utilization of oxygen at a rate faster than its resupply by physical processes. |
| pH | The negative log of the concentration of hydrogen ions in a solution. |
| Phytoplankton | Drifting photosynthetic microbes. |
| Polar Molecule | A molecule exhibiting positive and negative charges on different ends of the molecule. |
| Precipitating | The coming out of solution of a dissolved substance. |
| Principle of Constant Proportions | The constancy o of the ratios of the major constituents regardless of salinity. |
| Residence Time (General idea) | The time that a dissolved substance spends in a particular reservoir. |
| Salinity | The concentration of dissolved salts in seawater. |
| Solubility | The amount of a solute that can be dissolved by a solvent under a given set of conditions. |

| Trace Elements=Minor Constituents | Elements whose concentration in seawater is less than 1 part per million. (Lead, Mercury and Iodide) |
| Water Column | An undefined column of water stretching from the surface face to depth. |
| Pacific Plate | An oceanic tectonic plate that lies beneath the Pacific Ocean. It is the largest plate. |
| Nazca Plate | Named after the Nazca region of southern Peru, is an oceanic tectonic plate in the eastern Pacific Ocean basin off the west coast of South America. The ongoing subduction, along the Peru-Chile Trench, of the Nazca Plate under the South American Plate is largely responsible for the Andean orogeny. |
| Cocos Plate | An oceanic tectonic plate beneath the Pacific Ocean off the west coast of Central America, named for Cocos Island, which rides upon it. |
| South American Plate | A continental tectonic plate which includes the continent of South America and also a sizeable region of the Atlantic Ocean seabed extending eastward to the Mid-Atlantic Ridge. |
| North American Plate | A tectonic plate covering most of North America, Greenland, Cuba, Bahamas, and parts of Iceland and the Azores. It extends eastward to the Mid-Atlantic Ridge and westward to the Chersky Range in eastern Siberia. The plate includes both continental and oceanic crust. |
| African Plate | A tectonic plate which includes the continent of Africa, as well as oceanic crust which lies between the continent and various surrounding ocean ridges. |
| Australian Plate | A major tectonic plate that includes the continent of Australia and surrounding ocean, and extends northwest to include the Indian subcontinent and adjacent waters. It was formed by the fusion of Indian and Australian plates 43 million years ago |
| Indian Plate | A tectonic plate that was originally a part of the ancient continent of Gondwana from which it split off, eventually becoming a major plate. |
| Shelf Break | The transition between continental shelf and slope. |
| Coral Reefs | Very productive habitat with high species diversity. Found in warm, clear, shallow tropical waters. |
| Mid-Atlanic Ridge | A mid-ocean ridge, a divergent tectonic plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. |
| East Pacific Rise | A mid-oceanic ridge, a divergent tectonic plate boundary located along the floor of the Pacific Ocean. |
| Scientific Method | Observation, Hypothesis, Test Hypothesis, Analyze data, Reject Hypothesis? (yes or no) |
| Problems people create for the ocean: | Global warming, Ozone depletion, habitat destruction, overfishing, marine pollution, Eutrophication, oil spills and invasive species. |
| Transform Boundaries | A plate boundary where two plates move horizontally relative to each other. |
