← GeographyWhich outcome occurs when the angle of a transform fault relative to the spreading ridge decreases significantly?
A)Increased strike-slip faulting frequency
B)Enhanced magma upwelling events✓
C)Wider oceanic crust formation
D)Reduced hydrothermal vent activity
💡 Explanation
Decreasing the transform fault angle induces increased extensional stress due to plate divergence exceeding lateral movement rates. Partial melting of the mantle accelerates because of the reduced lithospheric thickness, leading to enhanced magma upwelling and volcanism, rather than just strike-slip events.
