The Seafloor Spreading Theory

The mid ocean ridge is where the seafloor spreading occurs in which tectonic plates large slabs of earth s lithosphere split apart from each other.

The seafloor spreading theory.

Seafloor spreading helps explain continental drift in the theory of plate tectonics. Mantle convection is the slow churn ing motion of earth s mantle. Seafloor spreading is a geologic process in which tectonic plate s large slabs of earth s lithosphere split apart from each other. 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.

The theory of seafloor spreading. This idea played a pivotal role in the development of the theory of plate tectonics which revolutionized geologic thought during the last quarter of the 20th century. Seafloor spreading is the mechanism by which new seafloor lithosphere is constantly being created at mid ocean ridges. Seafloor spreading and other tectonic activity processes are the result of mantle convection.

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