The rate at which temperature decreases with increasing altitude is:
The rate at which temperature decreases with increasing altitude is:
(A) Temperature slope
(B) Lapse rate
(C) Sounding
(D) Thermocline
The lapse rate is the standard meteorological term for the rate at which an atmospheric quantity, such as the temperature, decreases when you go to a higher altitude. In the Earth's troposphere, the standard lapse rate is approximately 6.5 degrees Celsius per kilometer, or about 3.6 degrees Fahrenheit for every 1,000 feet. This is because the air pressure decreases with altitude, causing the expanding air to cool adiabatically.
