According to the EPA, chlorine in the stratosphere is believed to come
primarily from the CFCs rather than from volcanoes because
-) The rise in the amount of chlorine measured in the stratosphere over the
past 2 decades matches the rise of chlorine which has different natural sources
of chlorune overthe same period
-) The rise of chlorine in the statosphere matches the rise in CFCs over the
same period
-) samples of air taken over erupting volcanoes shows that volcanoes
contribute a small amount of chlorine in the stratosphere compared to CFCs
-) ALL OF THE ABOVE
