Which outcome occurs when differential weathering increases within a cirque basin?

💡 Explanation

Increased differential weathering weakens the rock in a cirque, which leads to accelerated glacial headwall erosion via the mechanism of 'nivation'. This occurs because freeze-thaw cycles destabilize the headwall, therefore increased erosion occurs, rather than reduced sediment or decreased sliding.

• Which outcome commonly results where oceanic transform faults terminate near subduction zones?
• Which outcome occurs when a stream's sediment load significantly increases following heavy deforestation?
• Which atmospheric effect results because of large planetary rotation?
• Which landslide risk increases when earthquakes occur on steep, deforested slopes with saturated soil?
• What increased geomorphological process results when vegetation is removed from an alluvial floodplain?
• Which geological hazard increases when groundwater extraction accelerates near a transform fault?
