← GeographyWhich outcome occurs in forearc regions when a subducting plate exhibits a shallow angle of descent?
A)Increased volcanic arc proximity to trench
B)Subsidence due to reduced mantle wedge flow
C)Enhanced forearc basin sediment deposition
D)Rapid uplift of the continental margin✓
💡 Explanation
When a subducting plate has a shallow angle, the overriding plate experiences strong compressional forces because of increased friction, leading to uplift of the forearc region. Therefore rapid uplift of the continental margin results, rather than volcanic proximity, subsidence, or sediment deposition that correspond to steeper subduction angles.
