Concept:The question asks us to identify the process that does
not release ozone-depleting substances into the atmosphere.
Explanation:The ozone (
O3) layer is damaged by chemicals such as chlorine, bromine, and nitrogen oxides.
Volcanic eruptions eject ash, sulfur compounds, and other gases that can contribute to ozone depletion.
Bush burning releases smoke and pollutants that harm the ozone layer.
Combustion of coal and oil produces nitrogen oxides and other gases that also lead to ozone depletion.
Evapotranspiration is the release of water vapour from plants and the ground into the atmosphere.
Water vapour (
H2O) is not an ozone-depleting substance.
Therefore, evapotranspiration does not lead to depletion of the ozone layer.
Answer:D. Evapotranspiration
