Target class: volcanic arc segment Context triple: [Tonga Ridge, instanceOf, volcanic arc segment]
-
A.
volcanic arc
chosen
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.
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.
-
D.
volcanic ridge
A volcanic ridge is an elongated, elevated landform created by successive volcanic eruptions and lava flows that solidify along a linear zone, often associated with tectonic plate boundaries or rift zones.
-
E.
volcanic complex
A volcanic complex is a geologic feature consisting of multiple related volcanic centers and associated deposits that have formed over an extended period of eruptive 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.
