Mid Ocean Ridge Plate Boundary

The production of new seafloor and oceanic lithosphere results from mantle upwelling in respo.

Mid ocean ridge plate boundary. Mid ocean ridges are divergent boundaries where convection currents in the mantle lift the ocean floor and produce a rift in the lithosphere that follows the crest of the ridge. As the plates separate molten rock rises to the seafloor producing enormous volcanic eruptions of basalt. Seafloor spreading is a geologic process in which tectonic plates large slabs of earth s lithosphere split apart from each other. New lithosphere is created by volcanic activity along the crest of the ridge and the plates on either side of the ridge are moving away from one another.

It separates the eurasian plate and north american plate in the north atlantic and the african plate from the south american plate in thesouth atlantic. Question 9 mid oceanic ridges and rift valleys are associated with which of the following. Mid ocean ridges occur along divergent plate boundaries where new ocean floor is created as the earth s tectonic plates spread apart. The ridge extends from a junction with the.

This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the. The magma erupts to the surface of the earth. The mid atlantic ridge mar is a mid ocean ridge a divergent tectonic plate boundary located along the floor of the atlantic ocean and the longest mountain range in the world. The mid atlantic ridge mar is a mid ocean ridge a divergent or constructive plate boundary located along the floor of the atlantic ocean and part of the longest mountain range in the world in the north atlantic it separates the eurasian and north american plates and in the south atlantic it separates the african and south american plates.

Show transcribed image text. At constructive plate margins mid ocean ridges will be formed. This feature is where seafloor spreading takes place along a divergent plate boundary. As the plates move apart very slowly magma rises from the mantle.

The rate of seafloor spreading determines the morphology of the crest of the mid ocean ridge and its width in an ocean basin. It typically has a depth of 2 600 meters and rises about two kilometers above the deepest portion of an ocean basin. A mid ocean ridge or mid oceanic ridge is an underwater mountain range formed by plate tectonics.
