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. |
