Which landform formation results from nivation within cirques?

💡 Explanation

Headwall retreat and bergschrund development results from nivation because freeze-thaw action erodes the rock at the headwall; therefore, cirque size increases, rather than esker formation which occurs due to subglacial fluvial processes.
