By contrast, C 2 and C 3 are additionally driven by a source in the open ocean and a sink over the continental shelf, which resemble the heat or nutrients fluxed from the open ocean …

If brand new ocean crust was being formed at the mid-ocean ridges, then the rocks either side of the ridge should show symmetrical patterns of magnetism.

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 rid… freight nycWebb28 juli 2024 · Seafloor Spreading Theory Mapping of the Ocean floor: Detailed research of the ocean configuration was done using sonic waves, and it contained a sender and a receiver.
