WebbSeafloor spreading in back-arc basins contrasts significantly with that along mid-ocean ridges, characterized by very distinct manifestations of hydrothermal activity imposed by a unique combination of mantle dynamics and crustal structure and composition (Baker et al., 2006; Ferrini et al., 2008; Martinez et al., 2006).Thus, it is not surprising that the … WebbWhat is the process of sea-floor spreading? In sea-floor spreading, the sea floor spreads apart along both sides of a mid-ocean ridge as new crust is added. As a result, the ocean floors move like conveyor belts, carrying the continents along with them. What is the evidence for sea-floor spreading?
