Seafloor Spreading The concept of seafloor spreading was proposed by Harry Hammond Hess in 1961 (an American geologist). He discovered the mid-Atlantic ridges i.e. mid-ocean ridges. It is a geologic process in which tectonic plates splits apart from each other. The process of seafloor spreading occurs at mid-oceanic ridges, in which a new oceanic crust is formed through volcanic activities and then gradually moves away from the ridges. Some Important evidence for seafloor spreading: Along the mid-oceanic ridges, volcanic eruptions are common and they bring huge amounts of lava to…
