Which risk increases when a subsurface Antarctic ice sheet undergoes basal melting?

💡 Explanation

Elevated solifluction occurs because basal melting saturates the active layer above the permafrost, decreasing its shear strength; therefore, the soil flows downslope more readily, rather than remaining stable due to sufficient friction.
