Which outcome results when subduction causes hydrothermal vent blockage?

💡 Explanation

Methane hydrate formation increases because vent blockage reduces methane release, causing accumulation and phase transition near the thermocline due to increased pressure; therefore, only methane hydrate increases rather than oxygen supply increasing or erosion declining.
