Which mechanism explains ice lens formation in permafrost?

A)Cryosuction causes preferential water migration
B)Osmosis concentrates dissolved mineral solutes
C)Heat pipes redistribute soil temperatures
D)Advection cycles air in porous mediums

💡 Explanation

As temperatures plummet, cryosuction drives upward water migration toward growing ice crystals due to phase transition's energy gradient creating suction; therefore, ice lenses expand rather than forming evenly throughout, because freezing point depression isn't influential.
