Target class: submarine trench Context triple: [Romanche Trench, instanceOf, submarine trench]
-
A.
oceanic trench
chosen
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.
-
B.
submarine basin
A submarine basin is a large, low-lying depression on the ocean floor that collects sediments and is often bounded by higher seafloor features such as ridges or continental margins.
-
C.
submarine mountain chain
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.
-
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.
oceanic basin
An oceanic basin is a large, geologically defined depression on the seafloor that collects ocean water and is bounded by continental margins, mid-ocean ridges, and other submarine features.
- 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.
