← GeographyWhich outcome follows accelerated crystallization within a lava dome?
A)Decreased dome structural integrity✓
B)Slower dome effusion rates
C)Increased vent gas pressure
D)Wider tephra dispersal patterns
💡 Explanation
Decreased dome structural integrity occurs because rapid crystal growth leads to localized stress concentrations, enabling brittle fracturing rather than plastic deformation via viscous flow, therefore the dome risks collapse rather than stable expansion.
