Match List I with List II and select the correct answer using the code given below the lists : List I (Agents of erosion) (A) Running water (B) Glacier (C) Wind (D) UndergroundWater List II (Topographical feature) 1. Cirque 2. Barchan 3. Rift Valley 4. Doline 5. Gorge Code A B C D

The matching of geomorphic agents to their respective landforms is as follows: (A) Running water is responsible for the formation of deep, steep-sided valleys known as gorges [t5]. (B) Glaciers create amphitheatre-like bowl-shaped depressions called cirques through erosional processes [t3]. (C) Wind (Aeolian) action in arid regions forms crescent-shaped sand dunes known as barchans. (D) Underground water (Karst) processes involve the chemical dissolution of limestone, leading to the formation of small depressions or sinkholes called dolines [c1][c2][t1]. While rift valleys are tectonic features formed by crustal extension rather than a primary agent of erosion listed here, the other pairings align perfectly with Option 1 (A-5, B-1, C-2, D-4). This classification is fundamental to physical geography and the study of landform evolution across different climatic regimes [t7][t8].
