Which risk increases when anoxic conditions spread to fjord sediments?

💡 Explanation

Methane gas accumulates in the fjord sediments because anaerobic decomposition occurs under anoxic conditions; therefore, expanding anoxia increases methane release rather than any change to fault lubrication and tectonic uplift, which are unrelated.
