Which outcome occurs during cirque formation with nivation?

💡 Explanation

Bergschrund wedging along the cirque headwall significantly enhances erosion by freeze-thaw because the bergschrund crevasse provides a space that readily introduces meltwater into cracks in the rock; therefore headwall erosion increases, rather than acceleration of the main glacier flow.
