Discus what is meant by sea floor spreading

WebSeafloor spreading helps explain continental drift in plate tectonics. At oceanic trenches, seafloor crust slides down and under continental crust. Earlier theories (e.g. by Alfred Wegener) of continental drift were that continents ' plowed ' through the ocean. WebJul 7, 2024 · The theory of seafloor spreading states that new ocean crust is continually being formed, and that this crust is slowly carried away from its point of origin over a period of time. The study of the repeated reversal of the Earth’s magnetic poles over time has provided convincing evidence of seafloor spreading.

WebWhat is seafloor spreading? Seafloor spreading is a geologic process in which tectonic plates large slabs of Earth’s lithosphere split apart from each other. Seafloor spreading occurs along mid-ocean ridges (large mountain ranges rising from the ocean floor). The Mid-Atlantic Ridge is formed in the Atlantic ocean because of seafloor spreading. WebSeafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. …

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. WebThe Seafloor spreading theory was proposed by the geophysicist Harry H. Hess in 1960. It is a phenomenon that happens at mid-ocean ridges, where new oceanic crust is formed by volcanic activity and then slowly moves away from the ridge. The basis of the theory is the fact that the age of the rocks of the seafloor is not the same throughout history.
