Briefly explain adiabatic lapse rate and one common misconception about it.

## Adiabatic Lapse Rate The **adiabatic lapse rate** is the rate at which air temperature changes with altitude as an air parcel rises or sinks without exchanging heat with its surroundings. - **Dry adiabatic rate**: ~10°C per 1,000 meters (~5.5°F per 1,000 feet) for unsaturated air - **Moist/saturated adiabatic rate**: ~6°C per 1,000 meters (varies with temperature) for saturated air, which cools more slowly due to latent heat release from condensation ## Common Misconception **Misconception**: *The adiabatic lapse rate is the same as the environmental lapse rate (actual temperature profile of the atmosphere).* **Reality**: The adiabatic lapse rate describes how a *moving air parcel* changes temperature, while the environmental lapse rate is the *measured* temperature change with altitude in still air. These are often different. The environmental lapse rate varies by location, time, and weather conditions, and comparing it to the adiabatic rate is actually how meteorologists determine atmospheric stability and predict weather patterns.
