Which outcome is accelerated when increased sediment deposition obstructs subduction zones?

💡 Explanation

Increased sediment causes higher friction, promoting tectonic plate coupling because the sediment acts as a lubricant to adhere the plates. Therefore, coupling increases rather than slipping; tremor events or altering mantle convection, because these are separate processes.

• Which volcanic outcome results when a confined eruption transitions directly from a lava dome collapse to intense pyroclastic flow?
• Which risk increases when rapidly rising floodwater overtops a natural levee along a major river?
• Following heavy tephra deposition, which outcome becomes increasingly likely due to changes in load distribution?
• Which consequence results when deep ocean productivity declines in a gyre?
