Which outcome occurs when magma viscosity increases inside a volcanic dome?

💡 Explanation

Increased magma viscosity increases dome extrusion pressure because viscous magma resists flow, leading to pressure buildup via the hydrostatic gradient; therefore dome rupture is more likely, rather than effusive lower eruptions.
