Seafloor Spreading Meaning In Hindi

Seafloor spreading definition a process in which new ocean floor is created as molten material from the earth s mantle rises in margins between plates or ridges and spreads out.

Seafloor spreading meaning in hindi.

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. Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. The outward movement of the seafloor from central underwater ridges as a result of plate tectonics the major cause of continental drift. Seafloor definition the solid surface underlying a sea or an ocean.

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. A series of processes in which new oceanic lithosphere is created at oceanic ridges. Video shows what seafloor spreading means.

Spreading rates determine if the ridge is fast intermediate or slow. Subduction and sea floor spreading are processes that could alter the size and form of the ocean. Ocean floor spreading definition. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor.

For instance the atlantic ocean is believed to be expanding because of its few trenches. 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. 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.
