Q2. Rivers, glaciers, and wind are powerful agents of erosion. Examine their roles in modifying landscapes and creating distinctive landforms. 15M
Difficulty level: Moderate
Reference: Insights ias
Why the question: The question is part of the static syllabus of General studies paper – 1 and mentioned as part of Mission-2025 Secure timetable. Key Demand of the question: You are required to explain the processes through which rivers, glaciers, and wind erode and transport materials, and how these processes create distinct landforms. Structure of the Answer: Introduction: Begin by defining erosion as the process through which natural forces remove and transport soil, rock, and sediment from one location to another. Introduce rivers, glaciers, and wind as three major agents of erosion. Body: Firstly, mention the Role of Rivers in Modifying Landscapes and Creating Landforms like Fluvial Erosion, creating features such as deltas and floodplains, V-shaped Valleys, Meander and Oxbow lakes. Next mention the Role of Glaciers in Modifying Landscapes and Creating Landforms: like Glaciers erode landscapes through plucking and abrasion, where ice picks up and grinds down rocks, Responsible for formation of U-shaped Valleys, Cirques and Arêtes, Drumlins and Eskers etc. Then, mention the Role of Wind in Modifying Landscapes and Creating Landforms (like Sand Dunes, Yardangs, etc. Also, cite examples. Conclusion: Rivers, glaciers, and wind are natural forces that shape Earth’s surface through erosion, transportation, and deposition, creating diverse and ever-changing landscapes.
