Match List-I with List—II and select the correct answer using the code given below the Lists : List-I (Geographical feature) A. Cirque B. Yardang C. Barkhan D. Drumlin List-II (Type of geographic process) 1. Erosional feature of wind 2. Depositional feature of glacier 3. Depositional feature of wind 4. Erosional feature of glacier Code :

Result
Your answer:  ·  Correct: A
Explanation

The geographical features are matched to their processes as follows: A. Cirque is an erosional feature of a glacier, described as a bowl-shaped depression or deep trough cut by ice at the heads of glacial valleys [5]. B. Yardang is an erosional feature of wind, characterized by streamlined ridges of compact sand or hard rock formed by wind abrasion in arid environments [1]. C. Barkhan (or Barchan) is a depositional feature of wind, specifically a crescent-shaped sand dune that moves downwind through sand accumulation on its slip-face. D. Drumlin is a depositional feature of a glacier, consisting of smooth, oval-shaped ridges or asymmetrical hills composed of glacial till and sediments deposited by retreating ice [4]. Therefore, the correct sequence is 4-1-3-2.
