Target class: back-arc basin volcanic system Context triple: [Tyrrhenian Sea volcanic province, instanceOf, back-arc basin volcanic system]
-
A.
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.
-
B.
subduction-related volcanic arc
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.
back-arc region
chosen
A back-arc region is the tectonic area located on the side of a volcanic arc opposite the subducting plate, often characterized by extension, rifting, and associated magmatism.
-
D.
volcanic rift zone
A volcanic rift zone is a linear region of the Earth's crust where tectonic plates are pulling apart, allowing magma to rise and create fissures, vents, and often aligned volcanic eruptions.
-
E.
volcanic hotspot
A volcanic hotspot is a localized area in the mantle where unusually hot, buoyant rock rises toward the surface, producing long-lived volcanic activity often far from tectonic plate boundaries.
- 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.
