← ScienceWhich instability arises when methane hydrate transitions phase?
A)Endemic resonance causes complete combustion
B)Clathrate decomposition spikes sediment porosity✓
C)Bridging corrosion collapses pipeline strength
D)Erosion reduces external hydrostatic pressure
💡 Explanation
Excessive methane release after *clathrate decomposition* reduces pore pressure because methane expands. Therefore, sediment cohesion decreases, promoting submarine landslides, rather than direct combustion or corrosion that methane alone could cause.
