Sea Floor Spreading In Chinese

Molten rock erupts onto the seafloor there then cools and rifts away from the ridge on either side in a process known as seafloor spreading.

Sea floor spreading in chinese.

Spreading rates determine if the ridge is fast intermediate or slow. Our interpretation is that symmetric seafloor spreading of 5 6 cm year full rate began at 31 ma at an e w trending ridge in the central part of the south china sea. Evidence of indochina block extrusion and south china sea seafloor spreading marine geophysical research 10 1007 s11001 013 9187 3 34 3 4 309 323 2013. 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.

As rifting seafloor spreading and collision processed subsidence also occurred in the south china sea. The thickest portions of the continental crust are associated with this type of boundary. 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. This idea played a pivotal role in the development of the theory of plate tectonics which revolutionized geologic thought during the last quarter of the 20th century.

Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. Determine whether the characteristic is associated with a transform plate boundary divergent plate boundary or convergent plate boundary. Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them. A profound consequence of seafloor spreading is that new crust was and still is being continually created along the oceanic ridges.

After a ridge jump of 50 km to. Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. The process of sea floor spreading the mid ocean ridge is the region where new oceanic crust is created.
