The Youngest Ocean Floor Is Found

Where ocean sediments are thickest c.

The youngest ocean floor is found.

What is a volcanic arc. The earth would increase in volume. The oldest one i. Molten lava pours out at the mid ocean ridge.

They are typically 200 million years old. Along deep sea trenches b. 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. Near ocean ridges d.

Where earth s magnetic field changes polarity. The crust overlies the solidified and uppermost layer of the mantle the crust and the solid mantle layer together constitute oceanic lithosphere. This dataset shows the age of the ocean floor along with the labeled tectonic plates and boundaries. It is composed of several layers not including the overlying sediment.

The rocks that make up the crust on the ocean s floor are youngest near the mid atlantic ridge. They are colored red in this picture. 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 spreading however is generally not uniform causing linear features perpendicular to the divergent boundaries.

The rocks are older yellow green further from the spreading ridge. 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 is the youngest ocean floor found. The oldest oceanic crust rocks in the oceans are found in the trenches.

The youngest rock in the oceans is found at mid ocean ridges where they are formed continually the oceanic crust. This globe shows the ages of rocks that make up the seafloor of the atlantic ocean. 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 youngest part of the ocean floor is found.

What would happen to earth if ocean floor were created at divergent boundaries at a faster rate than it is destroyed at convergent boundaries. Because of this the youngest sea floor can be found along divergent boundaries such as the mid atlantic ocean ridge.
