The Seafloor Spreading Theory

This theory introduced by harry hess was proven as patterns.

The seafloor spreading theory.

Mantle convection is the slow churn ing motion of earth s mantle. 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 helps explain continental drift in the theory of plate tectonics. The theory of seafloor spreading.

Seafloor spreading and other tectonic activity processes are the result of mantle convection. When oceanic plates diverge tensional stress causes fractures to occur in the lithosphere. 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 motivating force for seafloor spreading ridges is tectonic plate slab pull at subduction zones rather than magma pressure although there is typically.

Seafloor spreading is the mechanism by which new seafloor lithosphere is constantly being created at mid ocean ridges. 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 a geologic process in which tectonic plate s large slabs of earth s lithosphere split apart from each other.
