| Troposphere | all weather takes place |
| Stratosphere | contains almost all of ozone |
| Mesosphere | coldest layer in Earth's atmosphere |
| Thermosphere | Hottest temperatures of all layers of Earth's atmosphere - heated by solar radiation |
| How are winds named? | according to the direction from which they flow |
| Coriolis Effect | caused by rotation of Earth on its axis |
| Air/Water is deflected to the right or left in northern hemisphere. | right |
| How do winds move? | Winds move from high pressure to low pressure. |
| Humidity | amount of water vapor in the atmosphere |
| Dew Point | Temperature at which condensation rate = evaporation rate |
| condensation nuclei | solid particle in atmosphere that provides the surface necessary for water vapor to condense |
| Front | an area where two different air masses make contact. |
