Which boundaries is sea floor created. A divergent boundary occurs when two tectonic plates move away from each other. The divergent boundaries are the areas where plates are moving apart from one another. What kind of plate boundary is forming between the. New crust is mainly created at plate boundaries in mid ocean where the sea floor is spreading older crust is destroyed near the edges of oceans where plates collide and one subducts dives below the other and melts.

The impact of the colliding plates. Along these boundaries earthquakes are common and magma molten rock rises from the earth s mantle to the surface solidifying to create new oceanic crust. When two plates come together it is known as a convergent boundary. Sea floor spreading is the process in which new ocean floor is continually being formed as magma rises to the surface and hardens into rock.

Seafloor spreading can stop during the process but if it continues to the point that the continent is completely severed then a new ocean basin is created. The result is a split in the crust called a fracture zone that extends across the seafloor far beyond the small transform that created it. Boundary type movement types of crust involved sea floor created or destroyed. Divergent boundaries are formed where two plates pull apart from each other the most famous example is the mid atlantic ridge where the north american and eurasian plates diverge.

These are called divergent boundaries and mark places where new sea floor is being created. In the collision the denser plate is typically subducted meaning it slides below the. The edges of the plates that make up the lithosphere are called boundaries or margins. Where plates move apart new crustal material is formed from molten magma from below the earth s surface.

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. Between the spreading segments the sides of the transform boundary rub together. Because of this the youngest sea floor can be found along divergent boundaries such as the mid atlantic ocean ridge. Convergent boundaries are formed wherever two plates move toward each other.

But as soon as the seafloor spreads beyond the overlap the two sides stop rubbing and travel abreast.
