What type of gases are in magma?

Manuel

Hi Manuel,

The major gases in magma are water vapor (H2O), sulfur dioxide (SO2), and carbon dioxide (CO2). They usually make up only a tiny percentage of the magma by weight (often around 1% or less). However, because gases have such a huge potential to expand, even these tiny percentages have very large effects on the explosivity of an eruption.

Sincerely,

Scott Rowland
