Sea Floor Spreading In Chinese

A profound consequence of seafloor spreading is that new crust was and still is being continually created along the oceanic ridges.

Sea floor spreading in chinese.

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. Cuimei zhang zhenfeng wang zhipeng sun zhen sun jianbao liu zhangwen wang structural differences between the western and eastern qiongdongnan basin. Select all that apply. Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them.

Determine whether the characteristic is associated with a transform plate boundary divergent plate boundary or convergent plate boundary. Continental drift and seafloor spreading. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. Meaning pronunciation translations and examples.

Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. The thickest portions of the continental crust are associated with this type of boundary. 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. The process of sea floor spreading the mid ocean ridge is the region where new oceanic crust is created.

Spreading rates determine if the ridge is fast intermediate or slow. After a ridge jump of 50 km to. As rifting seafloor spreading and collision processed subsidence also occurred in the south china sea. 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.

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. The seafloor is the ground under the sea. The formation of the new crust is due to the rising of the molten material magma from the mantle by convection current.
