Q2. Explain the geographical factors responsible for the formation of ocean gyres. Assess their influence on marine pollution distribution. (10 M)
Difficulty Level: Medium
Reference: InsightsIAS
Why the question Ocean circulation systems such as gyres are crucial components of physical geography and have gained renewed attention due to their role in concentrating global marine plastic pollution. Key Demand of the question The question requires explaining the geographical processes responsible for the formation of ocean gyres and analysing how these circulation systems influence the spatial distribution and accumulation of marine pollution. Structure of the Answer Introduction Briefly introduce ocean gyres as large-scale circular ocean current systems formed due to the interaction of winds, Earth’s rotation and ocean basin configuration. Body Formation of ocean gyres: Mention the geographical mechanisms such as planetary winds, Coriolis effect and basin configuration responsible for creating large rotating current systems. Influence on marine pollution distribution: Explain how gyre convergence zones trap floating debris and lead to accumulation of plastics and other pollutants in specific ocean regions. Conclusion Highlight that understanding ocean gyres is essential not only for ocean circulation studies but also for addressing the growing global challenge of marine plastic pollution.
