Theory Of Sea Floor Spreading Was Proposed By

What evidence supports hess s theory of seafloor spreading.

Theory of sea floor spreading was proposed by.

First proposed in the early 1960s by the american geologist harry h. Which statement accurately describes how magnetic stripes in ocean rock provide evidence of seafloor spreading. On the basis of tharp s efforts and other new discoveries about the deep ocean floor hess postulated that molten material from earth s mantle continuously wells up along the crests of the mid ocean ridges that wind for nearly 80 000 km. Seafloor spreading theory of lithospheric evolution that holds that the ocean floors are spreading outward from vast underwater ridges.

Evidence that led to the development of plate tectonic theory in the 1960s came primarily from new data from the sea floor including topography and the magnetism of rocks. Seafloor spreading helps to explain continental drift in the theory of plate tectonics. First proposed in the early 1960s by the american geologist harry h. Hess proposed the idea that are places where.

Hess its major tenets gave great support to the theory of continental drift continental drift geological theory that the relative positions of the continents on the earth s surface have. Seafloor spreading was proposed by an american geophysicist harry h. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. The seafloor spreading hypothesis was proposed by the american geophysicist harry h.

The pattern of magnetic strips shows that the seafloor is expanding at mid ocean ridges. Seafloor spreading was proposed as a mechanism to drive the movement of the continents on the basis of symmetrical patterns of reversed and normal magnetic rocks on the sea. Hess its major tenets gave great support to the theory of continental drift continental drift geological theory that the relative positions of the continents on the earth s surface have. In 1912 when alfred wegener proposed that the continents had once been joined together and had split apart the biggest weakness in his hypothesis was the.

The mid atlantic ridge for instance separates the north american plate from the eurasian plate and the south american plate from the african plate the east pacific rise is a mid ocean ridge that runs through the eastern pacific ocean and separates the pacific plate from the north american. Check all that apply. Seafloor spreading theory of lithospheric evolution that holds that the ocean floors are spreading outward from vast underwater ridges.
