| Question | Answer |
| Increase of Water Temperature Causes | Direct sunlight, shallow water, thermal pollution, warmer air, runoff from dark paved surfaces. |
| Increase of Water Temperature Effects | Lower resistance to disease and less dissolved oxygen. |
| Decrease of Water Temperature Causes | Shade and deeper water. |
| Decrease of Water Temperature Effects | Higher resistance to disease and more dissolved oxygen. |
| Increase of Dissolved Oxygen Causes | Increases photosynthesis and cooler water. |
| Increase of Dissolved Oxygen Effects | Greater diversity of living things. |
| Decrease of Dissolved Oxygen Causes | Decreased photosynthesis, decomposition, increased carbon dioxide, and an algae bloom. |
| Decrease of Dissolved Oxygen Effects | Fewer kinds of living things will be able to survive. |
| Increase of pH (Basicity) Causes | Dissolved Minerals and increased photosynthesis. |
| Increase of pH (Basicity) Effects | Harmful or lethal to fish (if too basic) and plants will not grow. |
| Decrease of pH (Acidity) Causes | Acid rain, increased carbon dioxide, and decomposition. |
| Decrease of pH (Acidity) Effects | Fish eggs will not hatch and harmful or lethal to fish, frogs, and insects (if too acidic). |
| Increase of Conductivity Causes | Dissolved solids (added), reducing man-made pollutants, irrigation road, natural salts or minerals (limestone), sewage, and road salts. |
| Increase of Conductivity Effects | Salts dehydrate animal skin. |
| Decrease of Conductivity Causes | Dissolved solids (taken away), adding fresh water, and pH may change. |
| Decrease of Conductivity Effects | Adding fresh water, water systems may be healthier, and pH may change. |
| Increase of Nitrite/Nitrate Causes | Animal waste, decomposition, fertilizer, and sewage. |
| Increase of Nitrite/Nitrate Effects | The process of eutrophication will lower the amount of dissolved oxygen. |
| Decrease of Nitrite/Nitrate Causes | Water is diluted; removing animal waste, decomposition, fertilizer, and/or sewage from the water; and plants absorb nitrates. |
| Decrease of Nitrite/Nitrate Effects | Organisms will not be able to survive without the proper amount of nutrients in the water. |
