← GeographyWhich hazard reduction results when controlled degassing vents penetrate viscous lava domes?
A)Decreased over-pressurization potential✓
B)Increased convective cooling rate
C)Enhanced silica crystallization pathway
D)Neutralized volatile effluent acidity
💡 Explanation
Reduced over-pressurization arises from controlled gas release through increased permeability, because pressure cannot build to explosive levels. Thus, the likelihood of rapid dome collapse decreases, rather than enhancing cooling or changing chemical properties of magma via crystal nucleation or chemical treatments.
