Theory Of Sea Floor Spreading Was Proposed By

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.

Theory of sea floor spreading was proposed by. First proposed in the early 1960s by the american geologist harry h. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. The theory of seafloor spreading the mid ocean ridge is where the seafloor spreading occurs in which tectonic plates large slabs of earth s lithosphere split apart from each other. First proposed in the early 1960s by the american geologist harry h.

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. The seafloor spreading hypothesis was proposed by the american geophysicist harry h. 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. Check all that apply.

Which statement accurately describes how magnetic stripes in ocean rock provide evidence of seafloor spreading. Seafloor spreading theory of lithospheric evolution that holds that the ocean floors are spreading outward from vast underwater ridges. Seafloor spreading helps to explain continental drift in the theory of plate tectonics. 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.

What evidence supports hess s theory of seafloor spreading. Hess proposed the idea that are places where. 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.

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. When oceanic plates diverge tensional stress causes fractures to occur in the lithosphere. The pattern of magnetic strips shows that the seafloor is expanding at mid ocean ridges.
