Webb28 juli 2024 · Seafloor Spreading Theory Mapping of the Ocean floor: Detailed research of the ocean configuration was done using sonic waves, and it contained a sender and a receiver. It revealed that the ocean floor is not just a plain, but it is full of relief. To map the oceanic floor provided a detailed picture of the ocean relief. WebbHess’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 …

WebbEvidence for Seafloor Spreading. In 1960, Harry Hess studied Wegener’s theory. Hess proposed the radical idea that the ocean floors move like a conveyer belt, which in turn move the continents. Hess called this process Sea-Floor Spreading. Webb6 feb. 2024 · When sea floor is created at spreading centers magma is emplaced at shallow depth or erupted at the surface to form the crust of the growing plate. Certain minerals in the magma (e.g., magnetite) are sensitive to the Earth's magnetic field.

WebbSeafloor spreading is the continuous process of forming new igneous rock at midocean ridges by injection of magma that forms new seafloor. The process is continuous because forces cause opposite sides of the midocean ridge to constantly move apart, making new room for the process to repeat.
