Question

16. Which process(es) cause(s) thick sediment layers to accumulate along the boundaries of continental

Answer 1

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.
