| Front | Place where two air masses meet |
| Cold Front | When a cold air mass quickly pushes under a warm front |
| Warm front | When and area of warm air moves into an area of cool air |
| Ocean Current | Movements of large volumes of ocean water |
| Atmosphere | A mixture of gases surrounding the Earth |
| Troposphere | The area of the atmosphere where most weather takes place |
| Mesosphere | The coldest layer of the atmosphere |
| Thermosphere | Hottest layer of the atmosphere |
