  • 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. Eurasian spreading center
    The Eurasian spreading center is a tectonic plate boundary in the Arctic Ocean where the Eurasian and North American plates diverge, creating new oceanic crust along mid-ocean ridges such as the Nansen-Gakkel Ridge.
