The Sea Floor Spreading Theory Was Proposed By

Hess its major tenets gave great support to the theory of continental drift continental drift.

The sea floor spreading theory was proposed by.

Seafloor spreading and other tectonic activity processes are the result of mantle convection. The pattern of magnetic strips shows that the seafloor is expanding at mid ocean ridges. First proposed in the early 1960s by the american geologist harry h. Seafloor spreading is a geologic process in which tectonic plate s large slabs of earth s lithosphere split apart from each other.

Theory that new seafloor formed when magma was forced upwards toward surface at mid ocean ridge. Mantle convection is the slow churn ing motion of earth s mantle. By the use of the sonar hess was able to map the ocean floor and discovered the mid atlantic ridge mid ocean ridge. 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. The phenomenon is known today as plate tectonics. Seafloor spreading theory of lithospheric evolution that holds that the ocean floors are spreading outward from vast underwater ridges.

Naval electronics laboratory in san diego in the 1960s. He also found out that the temperature near to the mid atlantic ridge was warmer than the surface away from it. Harry hess princeton university scientist what does seafloor spreading help support. He published his theory in history of ocean basins 1962 and it came to be called seafloor spreading in the early 1960s dating of ocean core samples showed that the ocean floor was younger at the mid atlantic ridge but progressively older in either direction confirming the reality of seafloor spreading.

The seafloor spreading hypothesis was proposed by the american geophysicist harry h. Check all that apply. Seafloor spreading was proposed by an american geophysicist harry h. Who proposed the theory of seafloor spreading.

Which statement accurately describes how magnetic stripes in ocean rock provide evidence of seafloor spreading. A mystery solved 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 lack.
