Which process limits magma dome growth following eruption?

A)Viscosity-driven pressure balance
B)Isostatic rebound dynamics
C)Barometric pressure variation
D)Ephemeral hydrothermal convection

💡 Explanation

Viscosity increases resistance to flow, influencing pressure distributions within a sealed dome, culminating in internal equilibrium and limiting magma input because pressure increases overwhelm dome integrity; therefore dome volume stabilizes, rather than expanding due to sustained magma supply and reduced resistance.
