← GeographyWhich landform formation results from nivation within cirques?
A)Headwall retreat and bergschrund development occur✓
B)Eskers form from subglacial meltwater tunnels
C)Kames appear from stratified glacial deposits
D)Drumlins indicate ice flow bed deformation
💡 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.
