Which risk increases when a large oceanic gyre shifts its established position due to changed wind patterns?

💡 Explanation

When gyres shift, redistribution of energy changes sediment deposition rates because altered wave action exposes previously protected coastlines, increasing erosion. Therefore, increased coastal erosion results, caused by changed energy distribution, rather than changes to the ocean's overall thermohaline circulation, the deep ocean's volcanic activity, or earthquake frequency which are unrelated.

• Which mechanism causes coastal dune formation along lake shorelines with strong prevailing winds?
• Which outcome occurs when a continental plate converges at an oblique angle with another, accumulating stress?
• Which geographic outcome occurs when an oceanic plate subducts under a less dense continental plate?
• Which process forms rift valleys following continental rifting?
• Which outcome occurs when increased sediment accumulation exceeds a subduction trench's compressive strength?
