The Prosses Of Creating A New Ocean Floor Is Called

The process by which oceanic crust sinks into the mantle through a trench.

The prosses of creating a new ocean floor is called. The process by which new material is added to the ocean floor along the boundary between diverging plates. At a spreading center basaltic magma rises up the fractures and cools on the ocean floor to form new seabed. The process by which the ocean floor sinks into the mantle is known as. A long deep depression in the ocean floor where old oceanic crust sinks into the mantle.

The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century. Basalt the once molten rock that makes up most new oceanic crust is a fairly magnetic substance and scientists began using magnetometers to measure the magnetism of the ocean floor in the 1950s what they discovered was that the magnetism of the ocean floor around. Seafloor spreading is a process that occurs at mid ocean ridges. The process that continually adds new material to the ocean floor is called.

Bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics the outer rocky layer of the earth includes about a dozen large sections called tectonic plates that are arranged like a spherical jig saw puzzle floating on top of the earth s hot flowing mantle. Land masses move by ocean floor spreading which is the process in which the underwater volcanoes at rift zones make new ocean floor causing the old ocean floor to sub duct in a trench. An underwater mountain chain formed where new crust is created by seafloor spreading is called a mid. The process called destroys old oceanic.

Extrusive igneous rock sometimes lava erupts and flows from long cracks in the earths crust called fissures. Lava flows from fissures on the ocean floor at places where tension is causing the. A new ocean floor is constantly being produced through the process known as seafloor spreading. Powered by create your own unique website with customizable templates.

What forms when 2 oceanic plates move apart. New crust is formed at diverging oceanic plates. Plates that are not subducting are driven by gravity sliding off the elevated mid ocean ridges a process called ridge push. Plate tectonics and the ocean floor.
