Sea floor spreading could produce. Explain how the process of sea floor spreading can produce these orientations and relationships. Explain how the process of sea floor spreading can produce these orientations and relationships ages of magnetic stripes and their distance from the ridge crests best answer. Abstract we present an updated oceanic crustal age grid and a set of complementary grids including spreading rate asymmetry direction and obliquity. Our dataset is based on a selected set of magn.

Occurs when plates produce opposing tensional forces go the opposite direction and magma is rising from beneath the surface. As the plates move apart the rocks break and form a crack between. For instance the atlantic ocean is believed to be expanding because of its few trenches. 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.

Where is occurring today. The new lithosphere moves outward from the axis to the flanks of the ridge pushing the older crust from the ridge. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. Subduction and sea floor spreading are processes that could alter the size and form of the ocean.

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. The red sea has not yet completely split arabia from africa but a similar feature can be found on the other side of africa that has broken completely free. Knowing what you do about sea floor spreading and magnetic reversals suggest an explanation. At the same time older rock moves outward on both sides of the ridge.

Sea floor spreading begins at a mid ocean ridge which forms along a crack in the oceanic crust. Sea floor spreading is the process in which the ocean floor is extended when two plates move apart. Some magnetic stripes are wider than others. When seafloor spreading occurs plates move away from one another at the axis if the midocean ridge.

Due to this continuous seafloor spreading occurs and makes atlantic ocean floor to be connected to other continental crust making the ocean gets wider over the time. Seafloor spreading theory that oceanic crust forms along submarine mountain zones and spreads out laterally away from them.
