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.
The youngest seafloor occurs.
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.
Along mid ocean ridges d.
The total capacity of the world s ocean basins decreases during times of active sea floor spreading.

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.
Oceanic lithosphere thickens away from the mid ocean ridge primarily due to.
The youngest sea floor occurs.
Seafloor spreading occurs at spreading centers.
Randomly over the entire ocean basin ans.
This line of new relatively shallow rocks is known as the mid atlantic ridge.

Along active margins c.
The youngest sea floor occurs.
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.
Oceanic lithosphere thickens away from the mid ocean ridge primarily due to.
Molten rock rose upward beneath mid ocean ridges and that is material solidified to form oceanic crust basalt.
At a mid ocean ridge where sea floor spreading occurs.
Along mid ocean ridges.
Along passive margins b.
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 sea floor occurs.
Along mid ocean ridges d.
The mid atlantic ridge for instance separates the north american plate from the eurasian plate and the south american plate from the african plate the east pacific rise is a mid ocean ridge that runs through the eastern pacific ocean and separates the pacific plate from the north american.
A crustal accretion zone within the boundary zone where the ocean crust is youngest and an instantaneous plate boundary.
