| When burning coal or gasoline, known as fossil fuels, nitrogen is released to the air as | Nitric oxides |
| Lightening converts _____ into compounds that then can be washed into the soil by rain. | Nitrogen |
| People and animals exhale a gas and play a part in | Respiration |

| Burning fossil fuels releases more Nitrogen into the atmosphere and contributes to the ______________ effect. | Acid rain |
| When water is turned into water vapor | Evaporation |
| When clouds form and water vapor turns into liquid water droplets | Condensation |
| When water falls to the Earth in the form of rain, snow, sleet or hail | Precipitation |
| When water vapor is released back into the atmosphere by plants | Transpiration |
| When water runs across the land and collects in rivers, streams and eventually in the ocean | Runoff |
| Evaporation is caused by energy from the ____. | Sun |
| A region of land drained by a river system | Watershed |
| Water passes through this zone | Zone of Aeration |
