← GeographyWhich outcome follows persistent subduction at oceanic trenches?
A)Formation an accretionary wedge✓
B)Decreased global sea levels
C)Increased rift valley formation
D)Glacial isostatic rebound is accelerated
💡 Explanation
An accretionary wedge forms because material scraped off the subducting plate accumulates, driven by the subduction process itself; therefore, an accretionary wedge forms, rather than sea level changes which occur due to different global processes.
