Theory Of Sea Floor Spreading Was Proposed By

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.

Theory of sea floor spreading was proposed by. Which statement accurately describes how magnetic stripes in ocean rock provide evidence of seafloor spreading. First proposed in the early 1960s by the american geologist harry h. The motivating force for seafloor spreading ridges is tectonic plate slab pull at subduction zones rather than magma pressure although there is typically. 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. Check all that apply. 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. 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. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. 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.

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. What evidence supports hess s theory of seafloor spreading. Seafloor spreading was proposed by an 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.

First proposed in the early 1960s by the american geologist harry h. The seafloor spreading hypothesis was proposed by the american geophysicist harry h. Seafloor spreading helps to explain continental drift in the theory of plate tectonics.
