Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. The motivating force for seafloor spreading ridges is tectonic plate slab pull at subduction zones, rather than magma pressure, although there is typically significant magma activity at spreading ridges. Plates that are not subducting are driven by gravity sliding off the elevated mid-ocean ridges a process called ri… WebFeb 19, 2024 · Schematic diagram showing the mechanism of seafloor spreading.

WebWhen two tectonic plates split apart from each other a geologic process called seafloor spreading happens. 4. As tectonic plates converge, the other plate slides beneath the other plate or subduct. This process is called subduction. 5. As two tectonic plates split apart mid- ocean ridge is formed. WebApr 25, 2024 · Seafloor spreading is the process of magma welling up in the rift as the old crust pulls itself in opposite directions. Cold seawater cools the magma, creating a new crust. The upward movement and eventual cooling of this magma has created high ridges on the ocean floor over millions of years.
