Alfred Wegner

Why did the scientific community, not accept Alfred Wegner's theory at first? Alfred Wegners had an abundance of strong evidence such as there was similar fossil remains found on different continents proving that the Earth was once a supercontinent known as. Pangea. Alfred also found cogent evidence that proved certain coastal lines fitted together like a jigsaw puzzle. For example, when Wegner matched Africa and South America's coastline they fitted together forming part of the supercontinent. These were two convincing and credible sources that proved continental shift. According to the investigation 4 article it states, “Most scientist found serious flaws in Wegners hypothesis, and dismissed it outright. One major weakness was that Wegner failed to provide a mechanism, or an explanation for how continents move.” Alfred Wegner did not have enough corroboration on how to support his theory that Earth's continents move in relation to each other, so that continents currently separated by oceans were joined together in the past. The reason why the Alfred Wegner's theory was rejected by the scientific community was because of a lack of sources and evidence …show more content…
Alfred was lacking evidence in how the continents changed from a supercontinent to how they're located today. Different sources of authority and further evidence were able to explain Wegners idea For example, Geologists: Harry Hess, Lawrence Morley and Drummond Matthews. Geologist Harry Hess was able to find more evidence on continental drift through his discovery of sea floor spreading. According to Investigation 4 it says “Geology professor Harry Hess, who had used sonar during World War II to map
