Which land deformation results when thawing permafrost causes widespread ground subsidence?

💡 Explanation

When permafrost thaws, the melting ice weakens the ground because the ice acts as a binding agent, leading to subsidence and thermokarst formation. Therefore, thermokarst results, rather than eskers, drumlins, or kame terraces, requiring glacial deposition, not thaw subsidence.
