Which risk increases when a building constructed on permafrost causes thawing of ground ice at the foundation?

💡 Explanation

When a building thaws permafrost, soil compaction occurs because melting ice reduces volume leading to uneven support and structural stress. Therefore differential settlement is a risk, rather than methanogenesis, weathering, or seismicity, which depend on different environmental conditions and mechanisms.

• Which process establishes distinct stratification layers within a dimictic lake?
• Which risk increases when differential pressure forces magma into forming volcanic domes underneath a glacier?
• Which deformation occurs on continents undergoing isostatic rebound?
• Which risk increases following a large subduction-zone earthquake in coastal regions?
• Which mechanism primarily causes lobate terraces to form in high-latitude, gently sloping terrains during solifluction?
• Which phenomenon is intensified when the ascending branch of a Hadley cell overlaps with a warm ocean current?
