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) NOx D) CFCs E) UVB

Quizplus · Accepted Answer

CFCs (chlorofluorocarbons) are the primary man-made chemicals responsible for the depletion of the ozone layer. They were widely used in refrigeration, air conditioning, and aerosol sprays in the mid-20th century, and their release into the atmosphere led to the destruction of ozone molecules in the stratosphere. This has resulted in the formation of the ozone hole over Antarctica and increased levels of harmful UV radiation reaching the Earth's surface.
