Which mechanism limits cirque widening to specific elevation ranges?

💡 Explanation

Pressure melting reduces stresses at cirque floor depths, because lithostatic pressure raises the melting point; therefore basal sliding continues below the ice divide, rather than pressure melting being uniform at other elevations.
