Which risk does crust formation increase as lava cools?

💡 Explanation

Breakouts become more likely because crust formation insulates the liquid lava beneath, retaining heat; therefore, lava bursts through localized cracks, rather than cooling uniformly, creating new paths because sheet flow is a more uniform cooling pattern.

• Which outcome results as permafrost thaws within cryosol layers?
• Which atmospheric effect weakens the temperature gradient between tropics and poles?
• Increased flood risk results when groundwater's solvent exceeds a limestone aquifer's saturation primarily because of which mechanism?
• Which risk increases when lava cools rapidly subaerially?
• Which outcome occurs when loose sediment encounters persistent winds?
• Which outcome occurs when intense bioturbation disrupts sediment layering?
