| Abyssal Zone | Deep ocean zone |
| Adhesion | An attraction between molecules of different substances |
| Aquifer | This is a large deposit of groundwater that can be extracted and used. |
| Brackish | Water with salinity between salt water and fresh water |
| Capillary Action | A process powered by adhesion that causes water molecules to move upward through a narrow tube such as the stem of a plant. |
| Coagulation | Wastewater treatment step in which sticky particle clump together to form larger pieces called floc |
| Coal Ash Pond | Large water-filled hole in which burned coal from power plants is deposited |
| Cohesion | Attraction between molecules of the same substance |
| Condensation | The change from a gas to a liquid |
| Deep Currents | Ocean currents caused by differences in temperature and salinity |
| Disinfection | Wastewater treatment step in which UV light and chlorine (bleach) are used to kill bacteria |
| Dissolved Oxygen | Measurement of oxygen dissolved in the water |
| Evaporation | The change of a substance from a liquid to a gas |
| Filtration | Wastewater treatment step in which a series of filters is used to remove small particles |
| Freshwater | Does not contain any salt water and can be rivers, lakes, streams, ponds, and wetlands |
| Glacier | A large mass of moving ice and snow on land |
| Hadal Zone | Ocean trench zone |
| Hydraulic Fracturing | Extraction of natural gas by pumping pressurized water, chemicals, and sand into the ground. |
| Hydrosphere | All of the water on earth |
| Midnight Zone | Deepest layer of the ocean that has no light |
| Nutrient Pollution | Nitrate and Phosphate pollution often associated with fertilizer or animal waste run-off pollution which damages aquatic ecosystems |
| pH | Measurement of the acidity of water |
| Polarity | Any separation of charge into distinct positive and negative regions |
| Precipitation | Any form of water that falls from clouds and reaches Earth's surface. |
| Primary Consumer | Organisms, like small fish, that eat algae |
| Producer | Organisms, like algae, that convert sunlight into food |
| River Basin | An area of land that drains into a major river |
| Runoff | water that flows over the ground surface rather than soaking into the ground |
| Salinity | Measurement of the salt dissolved in water |
| Scavengers | Organisms that eat dead and decaying organisms |
| Secondary Consumer | Organisms, like large fish, that eat small fish |
| Sediment Pollution | Pollution from solid waste. |
| Sedimentation | Wastewater treatment step in which large floc settles to the bottom to form sludge |
| Specific Heat | The amount of energy required to raise the temperature of 1 gram of a substance by 1 degree celsius. |
| Sunlight Zone | Uppermost layer of the ocean |
| Surface Currents | Ocean currents caused by wind |
| Surface Tension | The force that acts on the surface of a liquid and that tends to minimize the area of the surface. |
| Toxic Chemicals | Pollution from factories made up of heavy metals like copper and iron |
| Transpiration | Evaporation of water from the leaves of a plant |
| Turbidity | A measure of how clear water is. |
| Twilight Zone | Layer of the ocean with minimal light |
| Waterborne Pathogens | Pollution from fecal waste made up of harm-causing organisms like E. coli |
| Watershed | The area between two river basins or an area that drains into a small river or stream. |
