← GeographyWhich outcome occurs when isostatic depression increases fjord depth?
A)Enhanced tsunami wave focusing✓
B)Amplified thermohaline circulation
C)Reduced sediment deposition rates
D)Decreased methane hydrate formation
💡 Explanation
Enhanced tsunami wave focusing results because greater depth amplifies wave energy via constructive interference; the focusing mechanism increases wave height in fjords. Therefore, tsunamis gain destructive power, rather than thermohaline changes, sediment decreases, or methane decreases.
