Where earth s magnetic field changes polarity.

The youngest part of the ocean floor is found.

Oceanic crust is about 6 km 4 miles thick. Because of this the youngest sea floor can be found along divergent boundaries such as the mid atlantic ocean ridge. Cratons are therefore always found within continents. The downward part of a convection current causes a sinking force that.

Near ocean ridges is defined as the study of the history of earth s magnetic field. It is composed of several layers not including the overlying sediment. Along deep sea trenches b. A craton is a stable part of the continental lithosphere which has survived several cycles responsible for the merge and the dislocation of supercontinents.

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 following features are shown at example depths to scale though each feature has a considerable range at which it may occur. Pulls tectonic plates toward one another. The spreading however is generally not uniform causing linear features perpendicular to the divergent boundaries.

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. 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. Where ocean sediments are thickest c.
