Sea floor spreading occurs at a rate of about.
The east pacific rise is a mid oceanic ridge a divergent tectonic plate boundary located along the floor of the pacific ocean it separates the pacific plate to the west from north to south the north american plate the rivera plate the cocos plate the nazca plate and the antarctic plate it runs south from the gulf of california in the salton sea basin in southern california to a point.
Spreading rate is the rate at which an ocean basin widens due to seafloor spreading.
1cm yr to 10 cm yr.
These age data also allow the rate of seafloor spreading to be determined and they show that rates.
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.
Subduction and sea floor spreading are processes that could alter the size and form of the ocean.
Ranges of spreading throughout the world s oceans.
For instance the atlantic ocean is believed to be expanding because of its few trenches.

Use the above equation to calculate spreading rate.
As upwelling of magma continues the plates continue to diverge a process known as seafloor spreading samples 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.
Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them.
Due to this continuous seafloor spreading occurs and makes atlantic ocean floor to be connected to other continental crust making the ocean gets wider over the time.
Measure from the center of the spreading center to a known age point on the plate rather than from 65 ma on the eastern plate to 65 ma on the western.
