Subduction is not always accompanied by compression and thrust faulting in the overriding plate. This is especially true when:
A) the overriding plate is either not moving toward the subducted slab relative to the asthenosphere, or it is moving away
B) the overriding plate is moving toward the subducted slab relative to the asthenosphere
C) no magma is created by the subduction process
D) an accretionary prism has developed at the convergent plate boundary

Question

Quizplus · Accepted Answer

Subduction without compression and thrust faulting in the overriding plate can occur when the overriding plate is not moving toward the subducted slab relative to the asthenosphere, or it is moving away. This relative motion affects the stress regime in the overriding plate, potentially reducing compression and the associated thrust faulting.
