← GeographyWhich outcome reliably occurs when accumulated stress along a transform fault exceeds the rock's shear strength?
A)Elastic rebound resulting in earthquake✓
B)Creep deformation without seismic activity
C)Magma intrusion creating volcanic activity
D)Tectonic subsidence forming a rift valley
💡 Explanation
When stress buildup surpasses rock shear strength, elastic rebound occurs because the fault plane ruptures suddenly, releasing energy as seismic waves causing an earthquake. Therefore, an earthquake results, rather than creep, volcanism, or subsidence which require different plate dynamics or crustal processes.
