plate tectonics according to wegners hypothesis
... According to Freeman J. ... Dysons suggests that modern genetics and the big bang theory are two that are tool driven, and the plate tectonic revolution as being one of the few concept driven revolutions. The evidence for plate tectonics was presented but, ”° diregarded for fifty years because it contradicted the prevailing dogma”± (Dyson 1). By analyzing the plate tectonic revolution, it seems that the concept was not disregarded, but waiting for evidential support that would be obtained through new tools. ... The theory of plate tectonics did not emerge until the integration of tools and concepts gave it proper support. In 1968, plate tectonics emerged as a unified comprehensive framework to understanding the Earth. According to the present theory, the earth is composed of various layers. ... 18B), plates move together, and the more dense plate sinks below the other, forming a subduction zone. ... At transform plate boundaries ( figure 19. ... Whereas plate tectonics is currently acccepted as a proper theory, it had a rough development. In the early 1900s, Alfred Wegner developed a hypothesis regarding the origin of the continents from a single landmass called Pangea (Figure19. ... Although Wegner died before he could see his theory through, he sparked interest in other scientists who began to test his hypothesis with tools that would further it and allow it to become accepted. ... By measuring the size and location of earthquakes using seismological tools, geologists have been ale to determine the plate boundaries and where most of the collisions or separations of the plates occur.
