• C. P – 2, Q – 1, R – 4, S – 3
• D. P – 4, Q – 3, R – 2, S – 1

Answer 1

The Correct Option is A

To solve this question, we need to match the geomorphic agents from Column I with their corresponding landforms in Column II. Let's analyze each geomorphic agent and its characteristic landform:

1. Wind: Wind is a major agent of erosion and deposition in desert areas. One of the significant landforms created by wind action is the Yardang. Yardangs are streamlined protuberances carved from bedrock or any other consolidated or semi-consolidated material by the dual action of wind abrasion by dust and sand. Hence, P (Wind) matches with 2 (Yardang).
2. Groundwater: Groundwater erosion, especially in limestone regions, creates specific landforms such as Doline. Dolines are small to medium-sized closed depressions that can form naturally by dissolution of limestone, typically in karst landscapes. Thus, Q (Groundwater) matches with 3 (Doline).
3. Glacier: Glaciers sculpt many unique landforms, one of which is the Drumlin. Drumlins are elongated hills formed by the streamlined movement of glacial ice sheets across rock debris, or till. So, R (Glacier) matches with 4 (Drumlin).
4. River: Rivers create various depositional and erosional features. A common depositional feature in a river floodplain is a Backswamp. Backswamps are marshy or swampy areas found when rivers deposit sediments in their floodplains. Hence, S (River) matches with 1 (Backswamp).

By matching each geomorphic agent with its corresponding landform, we conclude that the correct answer is P – 2, Q – 3, R – 4, S – 1.
