Target entity: Juan de Fuca Ridge Context triple: [Cobb Offset, seafloorSpreadingContext, Juan de Fuca Ridge]
-
A.
Juan de Fuca Ridge
chosen
Juan de Fuca Ridge is an underwater volcanic spreading center in the northeastern Pacific Ocean where new oceanic crust forms as tectonic plates diverge.
-
B.
East Pacific Rise
The East Pacific Rise is a major mid-oceanic ridge and seafloor spreading center in the eastern Pacific Ocean, where tectonic plates diverge and new oceanic crust is formed.
-
C.
Nansen-Gakkel Ridge
Nansen-Gakkel Ridge is a slow-spreading mid-ocean ridge located beneath the Arctic Ocean, forming part of the seafloor spreading system between the Eurasian and North American tectonic plates.
-
D.
Mendocino Fracture Zone
The Mendocino Fracture Zone is a major east–west-trending transform fault and fracture zone in the northeast Pacific Ocean that marks a significant boundary in the oceanic crust off the coast of northern California.
-
E.
Hawaiian–Emperor seamount chain
The Hawaiian–Emperor seamount chain is a long, age-progressive line of volcanic islands and underwater mountains in the Pacific Ocean that records the movement of the Pacific Plate over a stationary mantle hotspot.
