The environmental lapse rate is almost always the same as the adiabatic lapse rate.

Question

Quizplus · Accepted Answer

The environmental lapse rate and the adiabatic lapse rate are not always the same. The environmental lapse rate refers to the actual decrease in temperature with increasing altitude in the Earth's atmosphere. The adiabatic lapse rate, on the other hand, refers to the rate at which the temperature of a parcel of air changes as it rises or sinks through the atmosphere due to adiabatic cooling or heating. The adiabatic lapse rate can vary depending on factors such as the moisture content of the air and the altitude at which the parcel of air begins its ascent or descent.
