Why is sea floor spreading an important piece of evidence in support of plate tectonics?

Sea floor spreading is the process where new oceanic crust is formed. This is achieved by the upwelling of magma at mid oceanic ridges. This can cause a continuing displacement of ocean crust - almost systematic. As for why it is important... I'm not sure.

sea-floor spreading is important because it led scientist to develop and accept plate tectonic theory

∙ 10y agoSea floor spreading is actually the creation of new oceanic basaltic crust at divergent plate boundaries called mid-ocean ridges. Material from the asthenosphere becomes molten as convection currents cause it to rise toward the thin upraised boundary between plates there. /as it solidifies, it becomes new crust. Because new oceanic crust is being created there, older oceanic crust is being destroyed at trenches, where the colder, more dense oceanic crust is being drawn into the asthenosphere, completing the roughly 200 million year oceanic crust recycling period.THERE ARE ALSO PART OF AN EVIDENCE OF THE MOSTFAMOUS KNOWN SUPERCONTINENT ALSO kNOWN AS THE PANGEA

∙ 12y agoIt is important, because it can help scientist and other people understand why we have plate tectonics, or earthquakes. Volcanoes are a good piece of evidence in why sea floor spreading is important. Scientist need to know the source of all of the plate tectonics, so sea floor spreading is a start.

Before this discovery the theory was fairly universally ignored because "continents can not just slide around willy nilly through the solid rock of the crust". After this discovery the theory of Continental Drift gradually transformed into the theory of Plate Tectonics in which the continents are embedded in moving crustal plates.

What are three kinds of evidence scientists have discovered to support the idea of the ocean floor spreading?
molten material, magnetic stripes, and the ages of the rock.
What evidence is there to support the theory of sea floor spreading?
the newer rock is closer to the middle n th older ones spread along the sides
Does the sun support the process of plate tectonics?
No it does not, the molten core inside the Earth is what drives plate tectonics. The Sun has nothing to do with the process.
How did seafloor drilling help scientists find the evidence to support the seafloor spreading hypothesis?
people here are stupid , really the answer is not hi
How is magnesium used to support the theory of seafloor spreading?
No
Does seismologic evidence support plate tectonics?
yes it represets plate tectonics
Did Obama have gay sex in the back of a limousine?
There is no credible evidence to support this claim. It is important to rely on factual information and not engage in spreading unsubstantiated rumors.
How do ocean ridges and deep-sea trenches support the theory of sea floor spreading?
Sea Floor spreading has to do with the crust forming at ocean ridges and being destroyed at deep sea trenches.
What are pieces of evidence that support the idea of Pangaea?
Continental Fit, Fossil Evidence and Sea floor Spreading. I just did this in science a month ago. :)
What are Plate tectonics evidence?
The theory of plate tectonics has succumbed to the newer theory of continental drift. Scientists believe this theory today due to three main factors. First, the continents appear to fit together. When the continental shelves, as opposed to just the continents, are placed together, the fit appears uncanny. Second, the distribution of fossils is consistent with continental drift. Lastly, glacial deposits once covered parts of the earth that are currently tropical.ANSWER: The plate tectonics theory is relatively new and formulated only in the 1960s. The evidence listed above in the first answer can only support the continental drift theory which was developed by Alfred Wegener in 1912. Evidence that can support the plate tectonics theory are the age, depth of oceanic sediments, volcanic activity, geothermal gradient, gravity anomalies, paleomagnetism and seismologic evidence. If you are answering an exam question on evidence supporting plate tectonics, evidence supporting continental drift theory should only come later in your answer and should not be given too much emphasis, for the plate tectonics theory involves more than just the continental crust drifting around and cannot support the main hypotheses of the plate tectonics theory.
How do the ages of the rocks on the seafloor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
How does evidence that rocks farther from a ridge are older than rocks closer to the ridge support the idea of sea floor spreading?

dumb question. don't want to write it all
How do the ages of rock on the ocean floor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.

What are three types of evidence provided support for sea-floor spreading?
Seismic Waves, Rock formations, and the shapes of the continents over time
