Galápagos spreading centre

In plate tectonics, the Galápagos spreading centre, Galápagos spreading center or Cocos–Nazca rift is a divergent boundary that forms the western part of the Cocos–Nazca spreading centre between the Cocos and Nazca plates. It extends for over 1800 km (1100 miles) from close to the eastern boundary of the Pacific plate, the East Pacific Rise, in the west, to the Inca transform in the east. It consists of two main ridge segments linked by the Galápagos transform.
