Why can temperature increase in the stratosphere even though pressure decreases with height?
Answer and explanation
Correct answer: Pressure and temperature trends can be controlled by different causes
Pressure decreases upward because the column of air above becomes smaller and therefore exerts less weight. Temperature, however, depends on energy absorption as well as pressure. In the stratosphere, ozone absorbs ultraviolet radiation and converts part of that energy into heat, producing a temperature increase with altitude. Thus option A is correct; the other choices confuse separate physical relationships or make false claims.
