← GeographyWhich outcome occurs when a subducting oceanic plate encounters increased mantle resistance?
A)Increased megathrust earthquake frequency✓
B)Decreased volcanic arc magma production
C)Higher rate of seafloor spreading
D)Reduced transform fault slip rate
💡 Explanation
Increased mantle resistance during subduction will increase stress along the plate interface because locking occurs, and therefore megathrust earthquake frequency increases as stress release events become larger, rather than magmatic changes or plate boundary interactions.
