Along deep sea trenches b.
The youngest ocean floor is found.
What is a volcanic arc.
The youngest rock in the oceans is found at mid ocean ridges where they are formed continually the oceanic crust.
The oldest oceanic crust rocks in the oceans are found in the trenches.
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 earth would increase in volume.
They are colored red in this picture.
Oceanic crust is the uppermost layer of the oceanic portion of a tectonic plate it is composed of the upper oceanic crust with pillow lavas and a dike complex and the lower oceanic crust composed of troctolite gabbro and ultramafic cumulates.
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 crust overlies the solidified and uppermost layer of the mantle the crust and the solid mantle layer together constitute oceanic lithosphere.
They are typically 200 million years old.
This dataset shows the age of the ocean floor along with the labeled tectonic plates and boundaries.
The rocks are older yellow green further from the spreading ridge.
Near ocean ridges d.
The rocks that make up the crust on the ocean s floor are youngest near the mid atlantic ridge.
Oceanic crust is about 6 km 4 miles thick.
Where ocean sediments are thickest c.
The oldest one i.
Molten lava pours out at the mid ocean ridge.
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.
Where is the youngest ocean floor found.
Along the crest of mid ocean ridges.
What would happen to earth if ocean floor were created at divergent boundaries at a faster rate than it is destroyed at convergent boundaries.
The spreading however is generally not uniform causing linear features perpendicular to the divergent boundaries.
It is composed of several layers not including the overlying sediment.
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.
