Theory of plate tectonics when the concept of seafloor spreading came along scientists recognized that it was the mechanism to explain how continents could move around earth s surface.
Theory of seafloor spreading is supported by.
Seafloor spreading theory of lithospheric evolution that holds that the ocean floors are spreading outward from vast underwater ridges.
Supporters of continental drift originally theorize d that the continents moved drifted through unmoving oceans.
Hess its major tenets gave great support to the theory of continental drift continental drift.
Its discovery provided a mechanism for continental drift that alfred wegener could not explain.
The driver for seafloor spreading in plates with active margins is the weight of the cool dense subducting slabs that pull them along or slab pull.
First proposed in the early 1960s by the american geologist harry h.
In this lesson you will learn about this important.
A veritable legion of evidence supports the seafloor spreading hypothesis.
Harry hess s hypothesis about seafloor spreading had collected several pieces of evidence to support the theory.
Seafloor spreading is a part of plate tectonics.
Keeping earth in shape.
Since then it has been shown that the motion of the continents is linked to seafloor spreading by the theory of plate tectonics.
Seafloor spreading proves that the ocean itself is a site of tectonic activity.
This evidence however was also used to support the theory of continental drift.
Seafloor spreading disproves an early part of the theory of continental drift.
