Locations Of Sea Floor Spreading

Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them.

Locations of sea floor spreading.

Plate tectonics theory dealing with the dynamics of earth s outer shell that revolutionized earth sciences by providing a uniform context for understanding mountain building processes volcanoes and earthquakes as well as the evolution of earth s surface and reconstructing its past continents and oceans. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. 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. When oceanic plates diverge tensional stress causes fractures to occur in the lithosphere.

At the spreading center on a mid ocean ridge the depth of the seafloor is approximately 2 600 meters 8 500 ft. The process of sea floor spreading. Seafloor spreading helps to explain continental drift in the theory of plate tectonics. On the ridge flanks the depth of the seafloor or the height of a location on a mid ocean ridge above a base level is correlated with its age age of the lithosphere where depth is measured.

Part a identifying locations of seafloor spreading please determine whether or not. The mid ocean ridge is the region where new oceanic crust is created. You will differentiate between locations where seafloor spreading occurs and where it does not occur then relate the rate of plate movements to the rate of lithosphere creation. Lab activity 2 6 recognizing seafloor spreading there are several locations on the earth where seafloor spreading takes place.

In locations where two plates move apart at mid ocean ridges new seafloor is continually formed during seafloor spreading. The oceanic crust is composed of rocks that move away from the ridge as new crust is being formed.
