Which mechanism increases subsurface water content when permafrost thaws during warmer summers?

💡 Explanation

Increased temperatures cause permafrost thaw, resulting in ground subsidence because the ice volume transforms to water and soil compacts, creating depressions that trap surface and subsurface water. Ground subsidence creates water traps, rather than cryosuction, latent heat release, or hydraulic fracturing which require different underlying geological processes.
