The Seafloor Spreading Theory

The motivating force for seafloor spreading ridges is tectonic plate slab pull at subduction zones rather than magma pressure although there is typically.

The seafloor spreading theory.

Seafloor spreading is a geologic process where there is a gradual addition of new oceanic crust in the ocean floor through a volcanic activity while moving the older rocks away from the mid oceanic ridge. When oceanic plates diverge tensional stress causes fractures to occur in the lithosphere. Seafloor spreading is a geologic process in which tectonic plate s large slabs of earth s lithosphere split apart from each other. It leads to the formation of new material on the ridge.

This theory introduced by harry hess was proven as patterns. Sea floor spreading theory as per seafloor spreading theory the mid oceanic ridge is the region where at the crest of oceanic ridges through the rupture of the oceanic crust and the crack continuous new lava eruption thrusts into it consequently pushing the oceanic crust on either side. Seafloor spreading theory that oceanic crust forms along submarine mountain zones known collectively as the mid ocean ridge system and spreads out laterally away from them. Seafloor spreading and other tectonic activity processes are the result of mantle convection.

The theory of seafloor spreading. Mantle convection is the slow churn ing motion of earth s mantle. Seafloor spreading is the mechanism by which new seafloor lithosphere is constantly being created at mid ocean ridges.
