Target class: convergent margin Context triple: [Farallon–North American plate boundary, instanceOf, convergent margin]
-
A.
plate boundary
A plate boundary is the region where two or more tectonic plates meet and interact, often causing earthquakes, volcanic activity, and mountain building.
-
B.
subduction zone
chosen
A subduction zone is a tectonic boundary where one lithospheric plate sinks beneath another into the mantle, generating intense seismic activity, volcanism, and mountain building.
-
C.
submerged continental margin
A submerged continental margin is the gently sloping, geologically passive underwater extension of a continent, typically consisting of a continental shelf, slope, and rise that transition into the deep ocean basin.
-
D.
accretionary prism
An accretionary prism is a wedge-shaped mass of sediment and rock scraped off a subducting tectonic plate and accumulated at a convergent plate boundary.
-
E.
subduction-zone megathrust fault
A subduction-zone megathrust fault is a large, gently dipping fault at the interface between a descending oceanic plate and an overriding plate, where immense stresses accumulate and are released in powerful earthquakes and tsunamis.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
