Because of this the youngest sea floor can be found along divergent boundaries such as the mid atlantic ocean ridge.
The youngest part of the ocean floor is found.
The spreading however is generally not uniform causing linear features perpendicular to the divergent boundaries.
Where ocean sediments are thickest c.
Near ocean ridges is defined as the study of the history of earth s magnetic field.
Cratons are therefore always found within continents.
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.
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 downward part of a convection current causes a sinking force that.
Some cratons in canada and greenland shelter the oldest continental rocks in the world about 4 billion years old.
This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.
The oldest continental rocks are found in cratons.
Along deep sea trenches b.
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.
Pulls tectonic plates toward one another.
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.
Plates slide past one another at.
Oceanic crust is about 6 km 4 miles thick.
Where earth s magnetic field changes polarity.
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.
