The Youngest Part Of The Ocean Floor Is Found

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.

The downward part of a convection current causes a sinking force that. Where ocean sediments are thickest c. Plates slide past one another at. This dataset shows the age of the ocean floor along with the labeled tectonic plates and boundaries.

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. Some cratons in canada and greenland shelter the oldest continental rocks in the world about 4 billion years old. Oceanic crust is about 6 km 4 miles thick. The spreading however is generally not uniform causing linear features perpendicular to the divergent boundaries.

The youngest part of the ocean floor is found. Near ocean ridges d. It is composed of several layers not including the overlying sediment. Where earth s magnetic field changes polarity.

The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. 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. Near ocean ridges is defined as the study of the history of earth s magnetic field. Pulls tectonic plates toward one another.

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. A craton is a stable part of the continental lithosphere which has survived several cycles responsible for the merge and the dislocation of supercontinents. Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet.

Along deep sea trenches b. Where earth s magnetic field changes polarity.
