WebSeveral types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks … WebApr 9, 2024 · New oceanic crust forms at these ridges through seafloor spreading, which pushes the plates apart. These discoveries led to the development of plate tectonics in the late 1960s, which combined the ideas of continental drift and seafloor spreading to provide a comprehensive explanation of lithosphere movement.

WebDec 17, 2024 · Comparison: Continental Drift – See Floor Spreading – Plate Tectonics Plate Tectonics It was from the continental drift theory, convection current theory and the theory of seafloor spreading, the theory of Plate Tectonics was formulated. In 1967, McKenzie and Parker suggested the theory of plate tectonics. Morgan later outlined the theory in 1968. WebSeafloor Spreading The idea of continental drift circulated in scientific circles until World War II, when sounding gear produced new evidence of what the seafloor looked like. The …
WebHess’s model was later dubbed seafloor spreading by the American oceanographer Robert S. Dietz. Confirmation of the production of oceanic crust at ridge crests and its subsequent lateral transfer came from an … WebThe concept of seafloor spreading led to the development of the unifying Theory of Plate Tectonics, which states that Earth’s lithosphere (crust and uppermost mantle) is divided into large plates that interact with each other to create Earth’s Upload your study docs or become a Course Hero member to access this document Continue to access
WebBy explaining both the zebralike magnetic striping and the construction of the mid-ocean ridge system, the seafloor spreading hypothesis quickly gained converts and represented another major advance in the development of the plate-tectonics theory. WebWhat is Seafloor Spreading? The theory of seafloor spreading states that the Earth’s crust is in a continual state of growth and evolution. It happens as plates on the Earth’s surface move away. The space left behind between the plates is filled with new material, which slowly pushes the plates apart.
WebSeafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. The motivating force for seafloor spreading …
