Target class: undersea ridge Context triple: [Marie Tharp Ridge, instanceOf, undersea ridge]
-
A.
submarine mountain chain
chosen
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.
-
B.
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.
-
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.
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.
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.
- 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.
