← GeographyWhich outcome frequently occurs at subduction zones because of rapid plate convergence exceeding material strength?
A)Megathrust earthquake generation✓
B)Stable oceanic trench formation
C)Abyssal plain sedimentation
D)Passive continental margin expansion
💡 Explanation
Megathrust earthquakes happen because sudden stick-slip `elastic rebound' releases built-up stress when fault friction is overcome at subduction margins; therefore, strong earthquakes occur, rather than constant trench formation that would require continuous, gradual deformation.
