B. Subduction
Explanation:
Subduction is one of such processes that causes thick sequences of sedimentary layers to accumulate along the boundaries of continental and oceanic plates.
- Continental and oceanic plates meets at a subduction zone which is a convergent margin.
- At this zone, the dense oceanic plate subducts or dives into the weak and less dense asthenosphere below.
- As it subducts, the ocean floor sediments on top is peeled off and the slab of lithosphere pulls down.
- This causes an accretionary wedge between the two zones.
- Most the sediments will eventually get metamorphosed into a metamorophic rock.
