The crust and upper mantle make up earth s.
The youngest rocks on the ocean floor are located where.
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.
This line of new relatively shallow rocks is known as the mid atlantic ridge.
Where is the oldest ocean floor located.
Why are there no oceanic rocks older than 200 million years.
D near the poles.
The crust overlies the solidified and uppermost layer of the mantle the crust and the solid mantle layer together constitute oceanic lithosphere.
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.

1 the youngest rocks on the ocean floor are located.
Check answer the oldest ocean floor is located near the continents next to a subduction zone.
B far from mid ocean ridges.
The youngest rocks on the ocean floor are located at or near the ridge crest at the spreading zone or axis.
The seafloor spreading theory was proposed by harry hess.
The location of the youngest rocks on the seafloor shows that new rocks form in the middle of the ocean the same location as the shallowest area of the ocean.
C at oceanic ridges.
2 which boundaries are examples of divergent plate boundaries.
The youngest rocks on the ocean floor are located at mid ocean ridges.
The youngest ocean floor is located on the mid ocean ridge.
There are rocks on every continent that are 3 to 4 billion years old.
This is a region of new ocean floor formation therefore its composed of most recent.
