When environmental Lapse Rate (ELR) is equal to the Adiabatic Lapse Rate (ALR), then which of the following occurs?
(a) Sub adiabatic lapse rate
(b) Super adiabatic lapse rate
(c) Neutral lapse rate
(d) Adiabatic lapse rate
I have been asked this question in final exam.
My enquiry is from Dispersion of Air Pollutants, Contol of Gaseous Pollutants topic in chapter Air Pollution of Environmental Engineering
