Target class: intraplate rift Context triple: [West Antarctic Rift System, instanceOf, intraplate rift]
-
A.
continental rift
chosen
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.
-
B.
intraplate earthquake
An intraplate earthquake is a seismic event that occurs within the interior of a tectonic plate, far from plate boundaries, typically caused by the reactivation of ancient faults or stresses transmitted through the plate.
-
C.
oceanic spreading center
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.
-
D.
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.
-
E.
strike-slip fault
A strike-slip fault is a fracture in the Earth's crust where blocks of rock slide horizontally past each other, primarily due to shear stress.
- 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.
