| Algal Bloom | -caused when nitrates enter the body of water and aid in algae growth |
| Turbidity | a measure of the cloudiness of water from sediment, micropic organisms, or pollution |
| Examples of point-source pollution | drainage pipes, factory smokestacks, factory waste water, leakage from sewage pipes |
| Greenhouse Gases | gases in the atmosphere that absorb thermal energy from the sun |
| Remote Sensing | the collection of data from a distance; used to compare water over time and to make inferences about water quality |
| Temperature's effect on the level of dissolved oxygen in water-Cool Water | increases dissolved oxygen |
| Temperature's effect of dissolved oxygen in water-Warm Water | decreases dissolved oxygen |
| Hydrosphere | All of the water on earth |
| Examples of non-point source pollution | urban run-off; run-off from a major city; a city's air pollution; oil along a beach |
| Condensation | clouds form as a result |
| Effect of high turbidity on organisms that undergo photosynthesis | It would block necessary light and organisms would die |
| How water quality is tested | Remote sensing of images and on-the-ground testing of oxygen levels, temperature, nitrates, acidity, turbidity, and bioindicators |
| Why water quality is important | pollutants can harm organisms that live in water and can affect quality of drinking water |
| Why is water imporatant to life? | It supports biological functions; it keeps earth warm; it stabilizes temperatures on earth |
