Which consequence results when the thermal equilibrium of permafrost soil is disrupted by construction?

💡 Explanation

Increased ground temperature causes thawing of permafrost, so a thermokarst (uneven ground with waterlogged areas) forms via *thermokarst processes*, because ground ice melts and the surface collapses; therefore, this instability increases and is likely irreversible, rather than localized frost heave in stable soil structures.
