I think it was in 1912 that Alfred Wegner, from Germany, proposed the idea of continental drift and followed up on this idea in 1915 with his book "The Origin of Continents and Oceans". The established scientific community scoffed at the theory since there was no way to confirm such ideas at the time.
In the 1920's, English Geologist Artur Holmes proposed that the continental seams, or junctions, lay at the bottom of the oceans. Again, unconfirmable at the time.
Sometime in the mid 1950's the discovery of variable magnetic field directions, in rocks of different ages, became the first evidence that crust plates did move about. That discovery led to the acceptance of Wegner and Holmes work and the main stream scientific community jumped on the plate tectonics band wagon.
Deep sea research in the 60's aided in the development of Plate Tectonics and by the end of the 60's, as we were landing on the moon, the Theory of Plate Tectonics became universally accepted.
The theory of plate tectonics was developed in the mid-20th century, primarily in the 1960s. Scientists such as Alfred Wegener, Harry Hess, and J. Tuzo Wilson were key figures in formulating and advancing the concept of plate tectonics.
1915
alfred wagner
it wasnt accepted. Wegener's theory of continetal drift wasnt accepted. the theory of plate tectonics was created when scientists discovered about sea floor spreading and magnetic reversals. but i dont know when the theory of plate tectonics was created. so you can ask about that.
plate tectonics=D
Volcanoes don't help plate tectonics; volcanoes are the result of plate tectonics.
Plate tectonics
the crust cracks and magma fills in the space
yes plate tectonics are flat
plate tectonics
No plate tectonics on Mars
plate tectonics
Nope plate tectonics do not exist on Venus.
