Diagram Of The Sea Floor Spreading


Diagram Of The Sea Floor Spreading - seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor 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 plate the cocos this diagram provides evidence of seafloor spreading by showing the ages of ocean floor in the atlantic and eastern pacific oceans the red colors are the youngest parts of the seafloor where fresh new crust is formed as lava seeps up from the deep interior of the earth at spreading ridges as new crust forms at these spreading ridges older crust colored green in the diagram moves away from in seafloor spreading magma moves from the asthenosphere to the crust ocean large bodies of water sitting.

atop oceanic crust oceanic crust thin parts of the earth s crust located under the oceans oceanic ridge newly formed region of the oceanic crust upper mantle rigid the uppermost part of the mantle part of the lithosphere start studying seafloor spreading learn vocabulary terms and more with flashcards games and other study tools thus the result of seafloor spreading is the creation of new sea floor through the uplift of magma magma raises from asthenosphere new oceanic lithosphere moves from ridge and it thickens seafloor spreading takes place at midocean ridges and produces basalt the rock that makes up the oceanic crust the mid atlantic ridge and east pacific rise are ex les of midocean ridges midocean ridges reach a typical summit elevation of 2 700 meters below sealevel introduction on each side of the ridge sea floor moves from the ridge towards the deep sea trenches where it.

is subducted and recycled back into the mantle fig 2 a test of the hypothesis of sea floor spreading was provided by studies of the earth s mag ism sea floor spreading age of the rock is younger near the mid ocean ridge it is older near the trenches older sesfloor is denser and sinks below the ocean crust so the water level is deeper by the trenches and is less deep by the mid ocean ridge plate tectonics seafloor spreading as upwelling of magma continues the plates continue to diverge a process known as seafloor spreading s les collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading centre important evidence in favour of this process these
