Which natural source contributes significantly to the release of sulfur dioxide (SO2) into atmosphere ?
Volcanic eruptions
Volcanic eruptions option is correct.
The question asks specifically for a natural source. Volcanic activity is the dominant natural emitter of sulfur dioxide (SO₂) to the atmosphere: gas-rich basaltic and explosive silicic eruptions release millions of tonnes of SO₂ each year, with events such as Mount Pinatubo (1991) and Laki (1783) producing measurable stratospheric sulfate aerosol and short-term climatic cooling.
Automobiles, power plants and industrial combustion are all significant SO₂ sources, but they are anthropogenic (fossil-fuel burning), so they do not satisfy the “natural source” criterion of the stem.
