Match each geomorphic landform listed on the left with its corresponding formation process and characteristic feature on the right.
- VentifactA rock or pebble faceted, grooved, and polished by wind abrasion.
- DrumlinA streamlined, elongated hill of unstratified till shaped by glacial deposition.
- BergschrundA deep fissure formed near the headwall where moving glacier ice pulls away from stagnant ice or rock.
- Seif duneA steep-sided longitudinal sand ridge aligned parallel to the prevailing wind direction formed by aeolian deposition.
Answer
Ventifact matches with 'A rock or pebble faceted, grooved, and polished by wind abrasion'; Drumlin matches with 'A streamlined, elongated hill of unstratified till shaped by glacial deposition'; Bergschrund matches with 'A deep fissure formed near the headwall where moving glacier ice pulls away from stagnant ice or rock'; Seif dune matches with 'A steep-sided longitudinal sand ridge aligned parallel to the prevailing wind direction formed by aeolian deposition'.
Each feature corresponds to its specific agent and mode of formation: Ventifacts are produced by wind abrasion on rocks; Drumlins are depositional hills of glacial till; Bergschrunds are cracks formed by moving glacial ice near headwalls; and Seif dunes are depositional sand ridges parallel to prevailing winds.
