At which atmospheric boundary is the change from decreasing to increasing temperature most evident?
Answer and explanation
Correct answer: Tropopause
The relevant concept is the change in the atmospheric lapse rate at a boundary. Through most of the troposphere, temperature decreases as altitude rises. At the tropopause this decrease ends, and in the overlying stratosphere temperature becomes nearly constant initially and then increases because ozone absorbs ultraviolet radiation. Thus option A is correct. The mesopause marks a cold minimum, the exobase is an upper exospheric boundary, and sea level is not an atmospheric transition boundary.
