Subsequently, one may also ask, which of the following provides supporting evidence for seafloor spreading?
Evidence for Sea-Floor Spreading. Several types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves. This evidence led scientists to look again at Wegener's hypothesis of continental drift.
Secondly, what are the evidence of seafloor spreading theory? Seafloor spreading, theory that oceanic crust forms along submarine mountain zones, known collectively as the mid-ocean ridge system, and spreads out laterally away from them.
Hereof, what is paleomagnetic evidence and how does it support the concept that the seafloor is spreading?
The symmetric banding is the result of seafloor spreading on both sides of a mid-oceanic ridge. This explanation of magnetic striping by paleomagnetism convinced scientists that new oceanic crust was being continually formed at mid-oceanic ridges. Seafloor spreading was accepted as a reality.
How did seafloor spreading provide evidence for continental drift?
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. At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed.
