← GeographyWhich outcome typically occurs offshore during subduction initiation?
A)Formation of a forearc basin✓
B)Increased abyssal plain sedimentation
C)Extensive salt dome development
D)Rift valley widening accelerates
💡 Explanation
A forearc basin forms during subduction initiation because flexural loading causes subsidence between the volcanic arc and accretionary wedge; therefore, sediment accumulates in the depression, rather than affecting processes like abyssal plains or rift valleys.
