Process Of Sea Floor Spreading

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.

Process of sea floor spreading. Most divergent boundaries are found on the ocean floor. Sea floor spreading is the process in. Seafloor spreading as upwelling of magma continues the plates continue to diverge a process known as seafloor spreading. Seafloor spreading and magnetic striping rising magma assumes the polarity of earth s geomagnetic field before it solidifies into oceanic crust.

What happens during the process of seafloor spreading. Samples collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading centre important evidence in favour of this process. 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. Seafloor spreading and other tectonic activity processes are the result of mantle convection.

A process in which new ocean floor is created as molten material from the earth s mantle rises in margins between plates or ridges and spreads out. Scientists originally believed that drifting was an occurrence exclusive to continents through continental. Continental drift causes sea floor spreading. The process of seafloor spreading leads to the formation of numerous geographical features which.

Seafloor spreading is a process that occurs at mid ocean ridges where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. At spreading centres this crust is separated into parallel bands of rock by successive waves of emergent magma. These boundaries are places where new oceanic crusts forms through the process of sea floor spreading.
