breakup of Rodinia
E790078
The breakup of Rodinia was a major Neoproterozoic tectonic event in which the ancient supercontinent fragmented into separate landmasses, profoundly influencing global climate, ocean circulation, and the subsequent assembly of later supercontinents.

How this entity was disambiguated
This entity first appeared as the object of triple T9304045 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: breakup of Rodinia Context triple: [Neoproterozoic supercontinent cycle, hasMainPhase, breakup of Rodinia]
-
A.
breakup of Gondwana
The breakup of Gondwana was a major tectonic event during the Mesozoic era in which the ancient southern supercontinent fragmented into the continents and oceanic plates of the Southern Hemisphere, reshaping global geography and climate.
-
B.
supercontinent Rodinia
Rodinia was an ancient supercontinent that assembled during the Proterozoic Eon and existed before the later supercontinent Pangaea, profoundly influencing Earth’s early tectonic and climatic evolution.
-
C.
supercontinent Pannotia
Supercontinent Pannotia was a short-lived late Proterozoic landmass that assembled near the end of the Precambrian and preceded the formation of the better-known supercontinent Pangaea.
-
D.
supercontinent Pangaea
Pangaea was a massive supercontinent that existed during the late Paleozoic and early Mesozoic eras, when nearly all of Earth's landmasses were joined together before breaking apart into the continents we know today.
-
E.
Precambrian Shield formation
The Precambrian Shield formation is an ancient, stable core of the Earth's crust composed mainly of very old igneous and metamorphic rocks that underlies much of central and eastern Canada and parts of the northern United States.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

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.
Input
Subject: breakup of Rodinia Description of subject: The breakup of Rodinia was a major Neoproterozoic tectonic event in which the ancient supercontinent fragmented into separate landmasses, profoundly influencing global climate, ocean circulation, and the subsequent assembly of later supercontinents.
