The Youngest Part Of The Ocean Floor Is Found

The youngest crust of the ocean floor can be found near the seafloor spreading centers or mid ocean ridges as the plates split apart magma rises from below the earth s surface to fill in the empty void.

The youngest part of the ocean floor is found.

This dataset shows the age of the ocean floor along with the labeled tectonic plates and boundaries. Near ocean ridges d. Near ocean ridges is defined as the study of the history of earth s magnetic field. Where earth s magnetic field changes polarity.

Oceanic crust the outermost layer of earth s lithosphere that is found under the oceans and formed at spreading centres on oceanic ridges which occur at divergent plate boundaries. The youngest part of the ocean floor is found. Because of this the youngest sea floor can be found along divergent boundaries such as the mid atlantic ocean ridge. Pulls tectonic plates toward one another.

It is composed of several layers not including the overlying sediment. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. The oldest continental rocks are found in cratons. Plates slide past one another at.

Along deep sea trenches b. Some cratons in canada and greenland shelter the oldest continental rocks in the world about 4 billion years old. The youngest part of the ocean floor is found at conservative plate boundaries where oceanic crust is pulled apart and magma rises from the mantle to form new oceanic crust. Cratons are therefore always found within continents.

Oceanic crust is about 6 km 4 miles thick. The youngest part of the ocean floor is found. Where earth s magnetic field changes polarity. Where ocean sediments are thickest c.

A craton is a stable part of the continental lithosphere which has survived several cycles responsible for the merge and the dislocation of supercontinents.
