| Term | Definition |
|---|---|
| Troposphere | Layer of the atmosphere closest to Earth's surface, where most of the mass of the atmosphere is found and in which most weather takes place and air pollution collects. |
| Stratosphere | Layer of Earth's atmosphere that is located above the troposphere and is made up primarily of concentrated ozone. |
| Mesosphere | Layer of Earth's atmosphere above the stratosphere. |
| Thermosphere | The layer between about 100 km and 500 km above Earth's surface. |
| Exosphere | The outermost layer of Earth's atmosphere. |
| Radiation | The transfer of thermal energy by electromagnetic waves. |
| Conduction | Occurs when two objects at different temperatures are in contact. |
| Convection | The transfer of thermal energy by the movement of heated material from one place to another. |
| Temperature Inversion | An increase in temperature with height in an atmospheric layer. |
| Humidity | The amount of water vapor in the atmosphere at a given location on Earth's surface. |
| Saturation | Occurs when the amount of water vapor in a volume of air has reached the maximum amount. |
| Relative Humidity | The amount of water vapor in a volume of air relative to the amount of water vapor needed for that volume of air to reach saturation. |
| Dew Point | The temperature to which air must be cooled at constant pressure to reach saturation. |
| Latent Heat | The extra thermal energy contained in water vapor compared to liquid water. |
| Condensation Nucleus | A small particle in the atmosphere around which water droplets can form. |
| Orographic Lifting | Occurs when an air mass is forced to rise over a topographic barrier. |
| Cumulus | Puffy, lump-looking clouds that usually occur below 2000 m. |
| Stratus | A layered sheetlike cloud that covers much or all of the sky in a given area. |
| Cirrus | Have wispy, indistinct appearance. |
| Precipitation | All forms of water that fall from clouds to the ground. |
| Coalescence | Occurs when cloud droplets collide and join together to form a larger droplet. |
