Question

Question 9 Multiple Choice Worth 3 points) With the discovery of magnetic reversals, there was evidence that the sea floor could create new continental crust. the seafloor contains alternate bands of minerals. only seafloor (oceanic) crust was capable of drifting. the sea floor was younger away from spreading centers. the seafloor contained a mechanism for plate tectonics.

Answer 1

Ans- E, the seafloor contained a mechanism for plate tectonics.

At the mid oceanic Ridge new crust creates. This type of setting is a divergent setting where continuous addition of new crust takes place. That's why the adjacent plates diverge away from each other. The magnetic minerals from the magma align themselves according to the present magnetic field direction. That's why as the magnetic field changes we find different strips of magnetic field in the oceanic crust.
