The environmental lapse rate is usually the same as the dry adiabatic rate.

Question

Quizplus · Accepted Answer

The Environmental Lapse Rate (ELR) refers to the actual rate at which temperature decreases with increasing altitude in the Earth's atmosphere. The Dry Adiabatic Rate (DAR) refers to the rate at which a parcel of dry air cools as it rises in the atmosphere. While the DAR is a constant rate of around 9.8°C per kilometer, the ELR varies depending on the atmospheric conditions and can be influenced by factors such as humidity, cloud cover, and atmospheric stability. Therefore, the ELR is not always the same as the DAR.
