← GeographyWhich outcome occurs when a newly formed volcanic island destabilizes?
A)Increased methane hydrate release on slopes✓
B)Accelerated island landmass sedimentation rate
C)Increased coastal upwelling and productivity
D)Reduced coastal marine ecosystem biodiversity
💡 Explanation
Destabilization triggers submarine landslides; this causes a rapid decrease in hydrostatic pressure. That reduction initiates massive Methane Hydrate Dissociation as methane is released because pressure decreases, therefore releasing methane, rather than suppressing it as in stable conditions.
