Target class: subduction zone arc Context triple: [Izu–Bonin Arc, instanceOf, subduction zone arc]
-
A.
subduction zone
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.
-
B.
subduction-related volcanic arc
chosen
A subduction-related volcanic arc is a curved chain of volcanoes that forms above a subducting tectonic plate where descending oceanic lithosphere melts and generates magma that rises to the overriding plate.
-
C.
volcanic arc
A volcanic arc is a curved chain of volcanoes that forms above a subducting tectonic plate, typically parallel to an oceanic trench, where magma generated by subduction rises to the surface.
-
D.
oceanic trench
An oceanic trench is a long, narrow, and extremely deep depression in the ocean floor, typically formed at convergent plate boundaries where one tectonic plate subducts beneath another.
-
E.
submarine mountain chain
A submarine mountain chain is a long, continuous series of underwater mountains, typically formed by tectonic plate movements and volcanic activity along the ocean floor.
- 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.
