Which structural outcome is most likely following extensive solifluction on an engineered slope in a periglacial region?

💡 Explanation

When repeated freeze-thaw cycles occur, solifluction triggers soil thawing and downslope movement because the process weakened by ice segregation causes a slow deformation and creep. Therefore surface cracking results rather than stabilization, reduced permeability, or enhanced vegetation, which normally prevent the effect of solifluction.
