    Volcanic and seismic events are major pieces of evidence towards proving that the plate tectonics theory is valid. The theory of tectonic plates was first posed by Alfred Wenger in 1912. Is the theory of how the earth lithosphere is made up of many separate pieces of the earth’s crust known as...

    the geophysical tools that are used today did not exist making the theory much more difficult to support. Paleomagnetism is one of the strongest pieces of evidence for plate tectonic theory and was developed in the 1950s which managed to convince scientists of the validity of the theory. When new...

All this evidence, both from the ocean floor and from the continental margins, made it clear around 1965 that continental drift was feasible and the theory of plate tectonics, which was defined in a series of...

    support the theory, although much of it requires tools which were not available when the theory was first developed such as accurate methods of mapping earthquakes. This made it difficult to prove the theory of plate tectonics as there were no hard facts. Although others may disagree, there are large amounts of evidence to prove the theory and so in my opinion the theory is a valid method....
