Which consequence occurs when repeated freeze-thaw cycles destabilize loess?

💡 Explanation

Freeze-thaw action promotes soil cracking. Cryoturbation weakens loess's structure, which allows for increased volumetric expansion due to water absorption. This destabilization leads to soil weakening, which increases expansive soil risk rather than braided streams, because increased mass movement is required.
