Spreading rates determine if the ridge is fast intermediate or slow.
Ocean floor spreading definition. What is the meaning of ocean floor spreading. Meaning pronunciation translations and examples. Define ocean floor spreading.
The mid ocean ridge is the region where new oceanic crust is created. Basalt the once molten rock that makes up most new oceanic crust is a fairly magnetic substance and scientists began using magnetometers to measure the magnetism of the ocean floor in the 1950s what they discovered was that the magnetism of the ocean floor around. What are synonyms for ocean floor spreading.
Ocean floor spreading definition. A series of processes in which new oceanic lithosphere is created at oceanic ridges. 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.
The formation of the new crust is due to the rising of the molten material magma from the mantle by convection current. The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century. N another term for seafloor spreading.
How do you use ocean floor spreading in a sentence. 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 process of sea floor spreading.
Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. The oceanic crust is composed of rocks that move away from the ridge as new crust is being formed.
