WebDescription. INTRODUCTION: Sea-floor spreading is the hypothesis that the sea floor moves sideways away from the crest of a mid-ocean ridge. The two sides of the ridge are moving in opposite directions leaving a rift that is the site of submarine volcanic eruptions.

The two sides of the ridge are moving … WebAt the mid-ocean ridge spreading axis, these flips in the direction of the Earth’s magnetic field are recorded in the magnetization of the lava. This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges. These patterns of stripes provide the history of seafloor spreading. ecowas citizenship

"WebSeafloor spreading was proposed by an American geophysicist, Harry H. Hess in 1960. By the use of the sonar, Hess was able to map the ocean floor and discovered the mid-Atlantic ridge (mid-ocean ridge). He also found out that the temperature near to the mid-Atlantic ridge was warmer than the surface away from it. " - The seafloor spreading

WebMay 20, 2024 · Seafloor spreading is most dynamic along giant underwater mountain ranges known as mid-ocean ridges. As the seafloor grows wider, the continents on opposite sides of the ridge move away from each other. The North American and Eurasian tectonic plates, for example, are separated by the Mid-Atlantic Ridge. WebThe seafloor’s permanent magnetic signatures showed that new ocean crust was created at the ridge crests and then spread outward in both directions. This seafloor spreading hypothesis had been proposed a few years earlier by Harry Hess, a petrologist at Princeton University, and Robert Dietz, an oceanographer in the US Coast and Geodetic ...
