Q2. Ocean waves are not merely surface phenomena but powerful agents shaping coastal geomorphology. Explain the processes involved. Assess their role in increasing coastal vulnerability under climate change. (10 M)
Difficulty Level: Medium

Why the question Ocean waves are not only geomorphic agents but also central to understanding rising coastal risks under climate change, making it relevant for both physical geography and contemporary concerns. Key Demand of the question The answer must explain the geomorphic processes by which waves shape coasts and then assess how these processes, under climate change, aggravate erosion, flooding, and vulnerability of coastal ecosystems and human settlements. Structure of the Answer: Introduction Briefly highlight the geomorphic role of waves and link to climate change impacts. Body – Processes involved in shaping coastal geomorphology – show erosional, depositional, and transport processes. Role in increasing coastal vulnerability under climate change – highlight erosion, salinity intrusion, ecosystem loss, and infrastructure risks. Conclusion Suggest need for integrated coastal zone management and resilience-building measures.

Structure of the Answer:
Introduction
Briefly highlight the geomorphic role of waves and link to climate change impacts.
Body –
• Processes involved in shaping coastal geomorphology – show erosional, depositional, and transport processes.
• Role in increasing coastal vulnerability under climate change – highlight erosion, salinity intrusion, ecosystem loss, and infrastructure risks.
Conclusion
Suggest need for integrated coastal zone management and resilience-building measures.
