WebbSeafloor spreading helps explain continental drift in the theory of plate tectonics. WikiMatrix Studies have been conducted at seafloor spreading centers, mid-plate … WebbSeafloor Spreading at Mid-Ocean Ridges Convection currents drive the movement of Earth’s rigid tectonic plates in the planet’s fluid molten mantle. In places where convection currents rise up towards the crust’s surface, tectonic plates move away from each other in a process known as seafloor spreading (Fig. 7.21).

WebbIn 1962 Hess proposed that the seafloor was created at mid-ocean ridges, spreading in both directions from the ridge system. At the spreading center, liquid rock called basaltic magma rises from the earth's mantle as it upwells beneath the spreading axis. When the magma hardens, it forms new oceanic crust that becomes welded to the original crust.
