← GeographyWhich consequence results when a lava dome's cooling rate decreases?
A)Increased dome edifice seismic stability
B)Decreased fractional crystallization completion levels
C)Elevation of explosive eruption potential✓
D)Augmentation of surrounding lithostatic pressure
💡 Explanation
Decreased cooling elevates gas retention via viscosity increase through magma solidification; therefore, explosive potential rises because increasing trapped pressure exceeds the tensile strength; rather than stabilizing domes, lithostatic augmentation, or impeding fractional crystallization.
