Short Definition For Sea Floor Spreading

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.

Short definition for sea floor spreading. Seafloor spreading synonyms seafloor spreading pronunciation seafloor spreading translation english dictionary definition of seafloor spreading. 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. N a series of processes in which new oceanic lithosphere is created at oceanic ridges spreads away from the ridges and returns to the earth s interior. Sea floor spreading synonyms sea floor spreading pronunciation sea floor spreading translation english dictionary definition of sea floor spreading.

Seafloor spreading definition a process in which new ocean floor is created as molten material from the earth s mantle rises in margins between plates or ridges and spreads out. The rate at which new oceanic lithosphere is added to each tectonic plate on either side of a mid ocean ridge is the spreading half rate and is equal to half of the spreading rate. These age data also allow the rate of seafloor spreading to be determined and they show that rates. That means the rock in the center is the youngest.

Spreading rates determine if the ridge is fast intermediate or slow. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. Seafloor spreading definition is the divergence at mid ocean ridges of the tectonic plates underlying the oceans that is due to upwelling from the earth s interior of magma which solidifies and adds to the spreading plates.

As the continents move apart whole new oceans.
