Satellite data and other measurements and models indicate that 75-85% of the observed ozone losses in the stratosphere since 1976 resulted from people releasing ____ and other ozone-depleting chemicals into the troposphere beginning in the 1950s. A) CO₂ B) CO C) NO_x D) CFCs E) UVB

Question

Quizplus · Accepted Answer

CFCs (chlorofluorocarbons) are known to be the main cause of ozone depletion since they are stable in the lower atmosphere but break down in the stratosphere to release chlorine atoms that destroy ozone molecules. This has been widely supported by satellite data, atmospheric measurements, and modeling studies. The other options (A, B, C, and E) are not directly related to ozone depletion or are not significant contributors.
