Which risk is amplified when a deep-sea hydrothermal vent plume's temperature significantly impacts seawater density?

💡 Explanation

Increased seawater temperature near vents reduces density which decreases its ability to stay at the sea floor, therefore the buoyancy effect sharply increases, allowing seabed methane hydrates to destabilize via thermal diffusion rather than diffusion into the water column.
