Which option correctly matches a layer with its main heat source?
Answer and explanation
Correct answer: Stratosphere—ultraviolet absorption by ozone
Ozone absorbs a significant part of incoming ultraviolet radiation in the stratosphere. The absorbed energy warms that layer and explains its characteristic temperature increase with altitude. Therefore option A is the correct match. The troposphere is heated mainly from Earth’s surface, not only by cosmic particles. The exosphere has no rainfall-driven condensation, and sea-wave heat does not constitute the main heat source of the mesosphere. These distractors assign processes to the wrong layers.
