Question

Quizplus · Accepted Answer

The dry adiabatic lapse rate is the rate at which temperature changes in a rising or descending parcel of unsaturated air due to adiabatic cooling or heating. It is approximately 10 degrees Celsius per 1000 meters (or 5.5 degrees Fahrenheit per 1000 feet) and is a constant value for unsaturated air.
