| Term | Definition |
|---|---|
| Troposphere | The layer closest to Earth's surface. |
| Stratosphere | Layer in which the air temperature mainly increases with altitude and contains the ozone layer. |
| Mesosphere | Layer where the temperature decreases with altitude. |
| Thermosphere | Layer that is extremely low density of air causes the temperature to rise. |
| Exosphere | The Outer layer that can be thout of as the transitional region between Earths atmosphere and outer space. |
| Radiation | The transfer of thermal energy by electromagnetic waves. |
| Conduction | Transfer of thermal energy between two objects when their atoms or molecules collide. |
| Convection | Transfer of thermal energy by the movement of heated material from one place of water. |
| Temperature Inversion | Increase in temperature with height in an atmospheric layer. |
| Humidity | Is the amount of water vapor in the atmosphere at a given location on Earths surface. |
| Saturation | Occurs when the amount of water vapor in a volume of air has reached the maximum amount. |
| Relative humidity | Is expressed as a percentage. |
| Dew point | Temperature to which air must be cooled at constant pressure to reach saturation. |
| Latent heat | Thermal energy contained in water vapor compared to liquid water. |
| Condensation nucleus | 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 | Clouds that are puffy,lumpy-looking that usually occur below 2000 m and 6000 m. |
| Stratus | Layered sheetlike cloud that covers much or all of the sky in a given area. |
| Cirrus | Clouds, often have a wizpy, indistinct appearance. |
| Coalescence | Occurs when cloud droplets collide and join together to form a larger droplet. |
