Which erosional outcome is intensified when meltwater becomes trapped within a cirque basin under freezing temperatures?

💡 Explanation

When meltwater is trapped within a cirque and freezes, ice segregation weathering occurs because water expands upon freezing, exerting pressure within rock fractures, accelerating breakdown. Therefore freeze-thaw weathering occurs rather than abrasion, deposition, or rebound, all of which require different driving mechanical constraints and longer scale processes related to either dynamic water flow or lithospheric dynamics.
