Seafloor Spreading | National Geographic Society
https://www.nationalgeographic.org/encyclopedia/seafloor-spreadingWebSeafloor spreading is a geologic process in which tectonic plates —large slabs of Earth's lithosphere —split apart from each other. Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is the slow, churning motion of Earth’s mantle. Convection currents carry heat from the lower mantle and core …

Seafloor spreading is the process of magma welling up in the rift as the old crust pulls itself in opposite directions. Cold seawater cools the magma, creating a new crust. The upward movement and eventual cooling of this magma has …
Seafloor Spreading - Plate Tectonics, Subduction Zone, Types
https://www.vedantu.com/geography/seafloor-spreadingWeb19 thg 1, 2023 · Seafloor spreading occurs at mid-ocean ridges and obtains basalt, the rock that forms the oceanic crust. Subduction zones are often observed near earthquakes. The biggest crash scene on Earth is the subduction zone. The oceanic crust is denser than the continental crust so when subduction occurs the oceanic crust goes under the …

https://www.studyiq.com/articles/seafloor-spreading-theoryWeb2 thg 1, 2023 · Seafloor Spreading Theory was put forth by American geophysicist Harry H. Hess in 1960. Magma rising in the rift as the old crust pulls itself in opposing directions causes the seafloor to spread. The seawater cools the lava, creating a fresh crust. Over millions of years, the magma’s upward flow and subsequent cooling produced high …

Sea Floor Spreading - INSIGHTSIAS
https://www.insightsonindia.com/.../first-order/sea-floor-spreadingWebSea-floor spreading — In the early 1960s, Princeton geologist Harry Hess proposed the hypothesis of sea-floor spreading, in which basaltic magma from the mantle rises to create new ocean floor at mid-ocean ridges. On each side of the ridge, sea floor moves from the ridge towards the deep-sea trenches, where it is subducted and recycled back ...
