Gulf of Aden spreading center

E354377

divergent plate boundary mid-ocean ridge seafloor spreading center

The Gulf of Aden spreading center is a tectonic plate boundary in the northwestern Indian Ocean where seafloor spreading occurs, linking the Red Sea rift to the Carlsberg Ridge and contributing to the opening of the Gulf of Aden.

How this entity was disambiguated

This entity first appeared as the object of triple T3375235 — 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.

Context triple: [Indian Ocean Ridge system, connectedTo, Gulf of Aden spreading center]

A. Galápagos Spreading Center
The Galápagos Spreading Center is a mid-ocean ridge segment in the eastern Pacific where tectonic plates diverge and new oceanic crust forms near the Galápagos Islands.
B. Indian Ocean Ridge system
The Indian Ocean Ridge system is a vast mid-ocean ridge network in the Indian Ocean where tectonic plates diverge and new oceanic crust is formed.
C. Southwest Indian Ridge
The Southwest Indian Ridge is a slow-spreading mid-ocean ridge in the southern Indian Ocean that forms part of the global system of divergent tectonic plate boundaries.
D. Southeast Indian Ridge
The Southeast Indian Ridge is a major mid-ocean spreading center in the southern Indian Ocean that forms part of the global system of divergent tectonic plate boundaries.
E. Cocos–Nazca spreading center
The Cocos–Nazca spreading center is a mid-ocean ridge in the eastern Pacific where tectonic divergence forms and separates the Cocos and Nazca plates.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
