Target class: back-arc spreading center Context triple: [East Scotia Ridge, instanceOf, back-arc spreading center]
-
A.
oceanic spreading center
chosen
An oceanic spreading center is a linear, submarine plate boundary where tectonic plates diverge and new oceanic crust is created by upwelling and solidification of magma.
-
B.
oceanic fracture zone
An oceanic fracture zone is a linear, seafloor feature formed by past transform fault activity that offsets and segments mid-ocean ridges, marked by steep escarpments and contrasting crustal ages on either side.
-
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.
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.
-
E.
continental rift
A continental rift is a linear zone where a continent is being pulled apart by tectonic forces, causing the crust to thin, fracture, and often form rift valleys and volcanic activity.
- 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.
