Which outcome is accelerated within a volcanic dome composed primarily of rhyolite as hydrothermal activity intensifies?

💡 Explanation

Phreatic explosions increase because increased hydrothermal circulation raises pore pressures within the dome, weakening the structure due to increased fluid inclusion; therefore, explosions occur more frequently rather than slow cooling because magma viscosity dominates that process.
