| Evaporation | When a liquid turns to a gas because of a temperature change. |
| Condensation | When a gas turns to a liquid. |
| Precipitation | Rain, sleet, snow or hail that is a result of a high level of humidity in the air. |
| Dew Point | The temperature where water begins to condense. |
| Lightning | An electrical discharge caused by atoms of water colliding as they condense. |

| Hurricane | A spinning column of air caused by large amounts of evaporating warm water. |
| Front | Where to air masses meet |
| Cold Front | Where warm air rises over cold air producing many days of rainy weather. |
| Warm Front | When warm air pushes cold air out of the way. Brings little rain followed by many days of warm weather. |
