The youngest part of the ocean floor is found.
A craton is a stable part of the continental lithosphere which has survived several cycles responsible for the merge and the dislocation of supercontinents.
Pulls tectonic plates toward one another.
Some cratons in canada and greenland shelter the oldest continental rocks in the world about 4 billion years old.
The downward part of a convection current causes a sinking force that.
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.
The youngest part of the ocean floor is found.
Where earth s magnetic field changes polarity.
It is composed of several layers not including the overlying sediment.
Near ocean ridges is defined as the study of the history of earth s magnetic field.
The youngest part of the ocean floor is found.
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.
Where ocean sediments are thickest c.
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.
The spreading however is generally not uniform causing linear features perpendicular to the divergent boundaries.
Plates slide past one another at.
Cratons are therefore always found within continents.
The oldest continental rocks are found in cratons.
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 earth s magnetic field changes polarity.
Because of this the youngest sea floor can be found along divergent boundaries such as the mid atlantic ocean ridge.
This dataset shows the age of the ocean floor along with the labeled tectonic plates and boundaries.
