Which outcome occurs when differential pressure increases within rhyolitic lava domes?

💡 Explanation

Block and ash flow generation increases during dome collapse, because high pressure causes increased instability and therefore debris avalanches from the dome's steep sides; rather than directly intensify phreatic activity with external water.

• Which process causes lateral stream deflection when strong prevailing winds encounter an advancing glacier?
• What outcome results from increased silica content during pyroclastic eruptions?
• Which outcome occurs when increased rainfall accelerates pedogenesis?
• Which risk markedly increases within deep karst caves upon prolonged, widespread surface pavement?
• Which effect results when upwelling brings nutrient-rich water to surface regions with stratification?
