Match each chemical species or atmospheric component to its primary environmental function or effect regarding global warming and ozone layer preservation:
- Chlorofluorocarbons (CFCs)Releases free chlorine radicals under UV radiation, catalytically breaking down stratospheric ozone
- Carbon(IV) oxide ()Absorbs outgoing thermal infrared radiation in the troposphere, intensifying the greenhouse effect
- Stratospheric ozone ()Filters out harmful solar ultraviolet radiation, preventing high-energy UV rays from reaching Earth's surface
Answer
Chlorofluorocarbons (CFCs) match with releasing chlorine free radicals that break down stratospheric ozone; Carbon(IV) oxide matches with absorbing outgoing thermal infrared radiation in the troposphere; Stratospheric ozone matches with filtering out harmful solar ultraviolet radiation.
Chlorofluorocarbons release chlorine free radicals that catalyze the breakdown of ozone molecules in the stratosphere. Carbon(IV) oxide is a major greenhouse gas that absorbs infrared heat radiation in the troposphere. Stratospheric ozone shields the Earth by absorbing harmful solar ultraviolet rays.
Step-by-Step Solution
Key Concept
Distinction between global warming mechanisms (infrared absorption by greenhouse gases) and ozone depletion mechanisms (ultraviolet photolysis releasing chlorine radicals).
