Sea floor spreading in chinese.

As rifting seafloor spreading and collision processed subsidence also occurred in the south china sea. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. 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. Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them.

Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. Meaning pronunciation translations and examples. 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. 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.

The process of sea floor spreading the mid ocean ridge is the region where new oceanic crust is created.

The thickest portions of the continental crust are associated with this type of boundary. A profound consequence of seafloor spreading is that new crust was and still is being continually created along the oceanic ridges.

Select all that apply. The formation of the new crust is due to the rising of the molten material magma from the mantle by convection current. 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. Continental drift and seafloor spreading.

Spreading rates determine if the ridge is fast intermediate or slow. The seafloor is the ground under the sea. 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.
