← GeographyWhich effect results when strike-slip motion along oceanic transform faults abruptly ceases?
A)Localized volcanic activity decreases dramatically
B)Seafloor spreading rates experience substantial acceleration
C)Hydrothermal vent fields become carbon-saturated
D)Tensional stress triggers normal faulting✓
💡 Explanation
Cessation of strike-slip motion means friction unlocks, therefore stored elastic strain then exceeds the frictional strength along the fault, therefore inducing tensional stress, triggering normal faulting, rather than compressive forces building, because subduction requires related compression.
