In Sea Floor Spreading Pieces Of Oceanic Crust

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. The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century. The second piece of evidence in support of continental drift came during the late 1950s and early 60s from data on the bathymetry of the deep ocean floors and the nature of the oceanic crust such as magnetic properties and more generally with the development of marine geology which gave evidence for the association of seafloor spreading along.

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.

In sea floor spreading pieces of oceanic crust.

In sea floor spreading pieces of oceanic crust. Move apart along a divergent plate boundary. Move down in a subduction zone. Move sideways against each other along a transform plate boundary.

As upwelling of magma continues the plates continue to diverge a process known as 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 theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them. The oceanic crust is composed of rocks that move away from the ridge as new crust is being formed. 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.

Youngest red is along spreading centers. These age data also allow the rate of seafloor spreading to be determined and they show that rates. Age of oceanic lithosphere. Move together along a convergent plate boundary.

The mid ocean ridge is the region where new oceanic crust is created. The process of sea floor spreading. The formation of the new crust is due to the rising of the molten material magma from the mantle by convection current. On the other hand unlike puzzle pieces some plates are being pushed underneath other plates usually oceanic under continental and new crust is being formed at spreading rifts.
