Theory Of Seafloor Spreading Is Supported By

Supporters of continental drift originally theorize d that the continents moved drifted through unmoving oceans.

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. Seafloor spreading disproves an early part of the theory of continental drift. Since then it has been shown that the motion of the continents is linked to seafloor spreading by the theory of plate tectonics. 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. In this lesson you will learn about this important. Like the scientists before us we will now merge the ideas of continental drift and seafloor spreading into the theory of plate tectonics. Seafloor spreading proves that the ocean itself is a site of tectonic activity.

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. This evidence was from the investigations of the molten material seafloor drilling radiometric age dating and fossil ages and the magnetic stripes. Hess its major tenets gave great support to the theory of continental drift continental drift. This evidence however was also used to support the theory of continental drift.

Seafloor spreading is a part of plate tectonics. 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.
