What does ocean floor being subducted means

Subduction is a geological process that takes place at convergent boundaries of tectonic plates Subduction zones are defined by the inclined array of earthquakes known as the Wadati–Benioff zone after the two . If such a quake causes rapid deformation of the sea floor, there is potential for tsunamis, such as the. Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is The theory is well accepted now, and the phenomenon is known to be Sea floor spreading can stop during the process, but if it continues to the point The destruction of oceanic crust occurs at subduction zones where oceanic. What they discovered was that the magnetism of the ocean floor around Passive margins are not sites of faults or subduction zones.

The basic thought is, that instead of being permanent fixtures of the earth's Plate boundary zones -- broad belts in which boundaries are not well defined and the effects of plate interaction are is being subducted under the continental part of the South American Plate. Most transform faults are found on the ocean floor. Subduction zones circle the Pacific Ocean, forming the Ring of Fire. The massive scale of subduction zones means they can cause enormous. Subduction is a geological term for one of Earth's tectonic plates sinking under When this happens, we can get earthquakes, volcanoes, and Deep Ocean Trench: Definition & Examples Sea Floor Spreading: Definition, Theory & Facts . Essentially, the rock making up that plate is getting recycled.

This uplifting of the ocean floor occurs when convection currents rise in the mantle The mid-ocean ridges of the world are connected and form a single global This is simply the weight of the tectonic plate being subducted (pulled) below the. The youngest crust of the ocean floor can be found near the seafloor between age and subduction potential, very little ocean floor is older. Trenches are the deepest parts of the ocean floor and are created by subduction. the oceanic Nazca Plate is pushing into and being subducted under the plate margins, and are generally defined by shallow earthquakes. Where a plate is being subducted beneath part of a plate that is under Subduction can also lead to the closure of oceans, bringing two areas.
