Which outcome from a lava dome results when crystallization increases viscosity?

💡 Explanation

Increased crystallization promotes brittle behavior, resulting in unstable dome structures. Block and Ash flow events occur because the increased viscosity enhances fragmentation during gravitational collapse, thereby accelerating pyroclastic flow, rather than promoting stability.
