Which process results in increased pressure inside a lava dome?

💡 Explanation

Viscosity-driven volatile accumulation raises dome pressure because high magma viscosity prevents gas escape, initiating positive feedback that traps gas. Trapped gases rapidly increase pressure, therefore escalating to potential explosive eruption, rather than gradual diffusion.
