Sulfur Dioxide - NASA

It is both human-generated and naturally occurring. SO 2is a precursor to sulfuric acid, a major constituent of acid rain. It is produced by the combustion of coal, fuel oil, and gasoline (since these fuels contain sulfur), and in the oxidation of naturally occurring sulfur gases, as in volcanic eruptions. Volcanic plumes, rich in ash and SO

Volcanic ash - Wikipedia

Volcanic ash is formed during explosive volcanic eruptions and phreatomagmatic eruptions, and may also be formed during transport in pyroclastic density currents. Explosive eruptions occur when magma decompresses as it rises, allowing dissolved volatiles (dominantly water and carbon dioxide) to exsolve into gas bubbles. As more bubbles nucleate a foam is produced, which
