Free Response Question
In the mid 1970’s, Sherwood Rowland and Mario Molina predicted a thinning of the
stratospheric ozone layer over Antarctica. The thinning was confirmed in the last
twentieth century and has continued into the twenty-first century.
(A) Identify the class of chemical compounds that is primarily responsible for the thinning
of the stratospheric ozone layer and describe TWO major uses for which these chemicals
were manufactured.
(B) Describe how the chemical compounds that you identified in part (A) destroy
stratospheric ozone molecules. You may include chemical equations as part of your
(C) Identify the major environmental consequence of the depletion of stratospheric ozone
and describe TWO effects on ecosystems and/ or human health that can result.
(D) Ozone formed at ground level is a harmful pollutant. Describe TWO effects that
ground-level ozone can have on ecosystems and/ or human health.
