Chlorofluorocarbons (CFCs)
Definition
Chlorofluorocarbons (CFCs) are synthetic compounds made up of carbon, chlorine, and fluorine atoms. They were commonly used in aerosol propellants, refrigerants, and foam-blowing agents but have been phased out due to their harmful effects on the ozone layer.
Analogy
Imagine CFCs as tiny troublemakers who poke holes in a protective shield. Just like how these troublemakers weaken a shield's ability to protect us from harm, CFCs weaken the ozone layer's ability to block harmful ultraviolet radiation from reaching Earth's surface.
