Which mechanism dominates mineral cave formation in permafrost?

💡 Explanation

Congelation segregation drives cave formation in permafrost. Ice lenses repeatedly grow and melt thus expanding fissures via dissolution as ice preferentially forms, because unfrozen water transports ions, therefore enlarging caves rather than simple surface weathering.

• Which mechanism causes shallow intra-plate earthquakes adjacent to transform boundaries?
• Which process initially establishes soil horizons in bedrock?
• Which process concentrates heavier minerals via aeolian deflation?
• Which outcome occurs when pore pressure rises rapidly during seismic shaking?
• Which erosional process primarily drives the formation of a cirque in mountainous regions?
• Which outcome results when intense offshore winds induce deflation?
