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.

• Which flow pattern arises when wind-driven surface currents converge toward the center of an ocean gyre?
• Which geographic feature results when prevailing wind encounters an obstacle, reducing its velocity and causing increased alluvial deposition?
• Which risk increases when intense rainfall occurs in heavily fertilized agricultural areas?
• Which outcome occurs when glaciers retreat in a cirque basin and leave behind meltwater?
• Which outcome occurs when prolonged aquifer depletion weakens strata?
• Which risk increases when concentrated agricultural runoff occurs above karst topography?
