Which landform results from glacial equilibrium line reduction?

💡 Explanation

The glacial erosion increases within the cirque through enhanced freeze-thaw action due to Regelation. This causes the steepening of headwalls, therefore cirques erode backwards into the mountain, rather than lateral moraine formation or stream alteration.
