The Youngest Part Of The Ocean Floor Is Found

Pulls tectonic plates toward one another.

The youngest part of the ocean floor is found.

The spreading however is generally not uniform causing linear features perpendicular to the divergent 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. Where ocean sediments are thickest c. Along deep sea trenches b.

Plates slide past one another at. Oceanic crust is about 6 km 4 miles thick. 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.

Near ocean ridges d. It is composed of several layers not including the overlying sediment. Some cratons in canada and greenland shelter the oldest continental rocks in the world about 4 billion years old. Where earth s magnetic field changes polarity.

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. A craton is a stable part of the continental lithosphere which has survived several cycles responsible for the merge and the dislocation of supercontinents. Near ocean ridges is defined as the study of the history of earth s magnetic field. 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. Where earth s magnetic field changes polarity. Cratons are therefore always found within continents. The youngest part of the ocean floor is found.

The downward part of a convection current causes a sinking force that. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.
