-
A.
Lomonosov Ridge
Lomonosov Ridge is a major underwater mountain range in the Arctic Ocean that stretches across the polar basin and plays a key role in regional geology and continental shelf claims.
-
B.
Mid-Atlantic Ridge
The Mid-Atlantic Ridge is a vast underwater mountain range and divergent tectonic plate boundary running down the center of the Atlantic Ocean, where new oceanic crust is formed.
-
C.
Gakkel Ridge
Gakkel Ridge is a slow-spreading mid-ocean ridge located beneath the Arctic Ocean, forming the tectonic boundary between the North American and Eurasian plates.
-
D.
Romanche Fracture Zone
The Romanche Fracture Zone is a major transform fault and deep-sea fracture zone in the equatorial Atlantic Ocean that offsets the Mid-Atlantic Ridge and hosts one of the deepest points in the Atlantic basin.
-
E.
Charlie-Gibbs Fracture Zone
The Charlie-Gibbs Fracture Zone is a major deep-sea transform fault system in the North Atlantic Ocean that offsets and disrupts the continuity of the Mid-Atlantic Ridge.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
