Which outcome occurs when silica content increases in magma?

💡 Explanation

An explosive volcanic eruption is more likely because higher silica content increases magma viscosity, hindering gas escape and promoting pressure build-up via volatile exsolution; therefore, explosive eruption intensity subsequently increases rather than decreasing lava viscosity alone.
