Seafloor spreading is a process that occurs at mid ocean ridges where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
The total capacity of the world s ocean basins decreases during times of active sea floor spreading.
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.
Randomly over the entire ocean basin ans.
The youngest sea floor is found near ocean ridges where magma is coming up and then cooling to form new crust.
At a mid ocean ridge where sea floor spreading occurs.
Oceanic lithosphere thickens away from the mid ocean ridge primarily due to.
The crust overlies the solidified and uppermost layer of the mantle the crust and the solid mantle layer together constitute oceanic lithosphere.
Along active margins c.
This line of new relatively shallow rocks is known as the mid atlantic ridge.
The youngest sea floor occurs.
On earth loose sediment which covers bedrock and has been chemically altered by reactions with rainwater and the addition of organic matter by the biosphere is termed.
Along mid ocean ridges.
Which soil horizon has the greatest proportion of organic matter.
A crustal accretion zone within the boundary zone where the ocean crust is youngest and an instantaneous plate boundary.
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.
Along mid ocean ridges d.
Molten rock rose upward beneath mid ocean ridges and that is material solidified to form oceanic crust basalt.

The youngest sea floor occurs.
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.
