| Question | Answer |
|---|---|
| Aquatic | having to do with water |
| Marine | aquatic ecosystems that contain dissolved salts |
| Salinity | refers to the amount of salt dissolved in a medium (salt water) |
| Photic zone | the surface layer of aquatic environment that is penetrated by sunlight |
| Salt marsh | temperate zone estuaries located along seacoasts |
| Estuary | environments where rivers meet the sea or where fresh water meets salt water contain a mixture of fresh water and salt water. |
| Lagoon | a body of water separated from a larger body of water by a reef or strip of land |
| Mangrove | coastal wetlands dominated by salt- tolerant plants. |
| Amoeba | a single –celled organism that ingests its food by engulfing it with appendages called pseudo pods, or false feet, same method used for movement/locomotion. |
| Extremophile | organism that lives in extreme environments. |
| Aquifers | underground layer of water and permeable rock where water can be extracted using a well. |
| Saturation | occurs when the space between soil particles are completely filled with water. |
| Solvent | a liquid that dissolves a solute such as salt |
| Homeostasis. | when a system is maintained at consistent internal environmental conditions |
| Surface tension | property of water that causes it to stick to others surfaces and allows things to float due to hydrogen bonding. |
| Point source pollution | any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory some stack. |
| Nonpoint source pollution | water pollution that enters a body of water from undefined sources |
| Clean water act | federal law that regulates and governs water pollution. |
| Effluent | an outflow of pollution into a body of water. |
| Urban runoff | when rainwater runs over roads and driveways within a city, picking up toxic substances and eventually running into a body of water. |

| Thermosphere | largest layer of the atmosphere above the mesosphere. |
| Exosphere | uppermost layer of the atmosphere |
| Air pollution | introducing substances into the air that may be harmful to living organisms or the environment |
| Particulates | small particles that are suspended within the atmosphere |
| Air pollutants | substances that cause air pollution |
| Primary pollutants | directly emitted from a process or source |
| Secondary pollutants | form in the air from the interaction between primary pollutants |
| Ozone | atmospheric gas |
| Ozone layer | layer of earth’s atmosphere that contains high amounts of ozone located about 5 to 30 miles above the earth’s surface within the stratosphere. |
| Radiation | a form of energy that can cause mutations resulting in cancer |
| UVB | a type of radiation emitted from the sun that can be beneficial and damaging to humans |
| Ozone depleting substances (ODS) | substance that destroys ozone |
| Chlorofluorocarbons(CFCs) | used as coolants, solvents and propellants |
| Halon | a ozone depleting substance that is used to extinguish fires |
