Alfred Wegener was a meteorologist and astronomer. He was the first scientist to introduce the theory of the continental drift. Wegener theorized that at one time the continents were one large landmass or Pangaea that had drifted apart. His ideas were initially rejected by other scientists. It was not until long after Wegener’s death that proof was obtained and his theory verified. The Life of Alfred Wegener Alfred was born in Germany in 1880 and led a very busy life. He received a PhD in astronomy
proponents of the new idea but it came in time and after much debate. Shifting from one theory to another after the original idea has existed and been accepted for so long never sits well with scientists. This same shift of ideas is true for Alfred Wegener and his theory of Pangaea and plate tectonics. Wegener’s theories gave a plausible explanation for the presence of the same species of fossils found on two different continents. His theory refuted the current theory of huge land bridges that

Wegener’s Theory Continental Drift was a far-fetched theory when German scientist Alfred Wegener first proposed it in 1915. At the time, many geologists were convinced “that the continents and ocean basins had fixed geographic positions.” (Lutgens Tarbuck 2014). Wegener was a meteorologist by profession, not a geologist. He studied the atmosphere and weather patterns (Hoffman 2012) and went on scientific expeditions to measure

Antarctica as well as many smaller, microplates such as the Arabian Plate and Indian Plate. Plate tectonic theory began in 1915 and was first suggested by Alfred Wegener with his theory of continental drift. Wegener proposed that the continents moved through crust of ocean basins, which made them look like they fit together like a puzzle. Wegener was not the first one to notice that the edges of different plates are really similar and seem able to fit each other. Magellan and other early explorers
forming into the seven continents we have today. The first comprehensive theory of continental drift was suggested by the German meteorologist Alfred Wegener in 1912. The hypothesis asserts that the continents consist of lighter rocks that rest on heavier crustal material, similar to the manner in which icebergs float on water. Wegener contended that the relative positions of the continents are not rigidly fixed but are slowly moving at a rate of about one yard per century. However
However, following Wegener’s theory, geologists such as Arthur Holmes were able to further develop these ideas, leading to the acceptance of the plate tectonics theory. The evidence that Wegener provided for his theory, was also useful evidence in proving that the plate tectonics theory is valid. Firstly, Wegener noticed that continents such as Africa and South America were able to fit together like a jigsaw puzzle. He also observed that animals and fossils in widely separated lands were similar.
the earth’s lithosphere is an individual rock that was broken down into fragmented plates that ride next to each other. This theory was first discovered by Alfred Wegener in 1912, he noticed that the coast lines of the west coast in Africa and the east coast of southern America seem to match up like a jigsaw puzzle. Further in his discoveries and in examining the globe, it revealed that all the earths’ continents had at one time been connected in a supercontinent called Pangaea, which is a Greek
existence, and life itself. Mr. Darwin’s courage to publish his work was a valiant act due to the uncalculated risks of publishing work that completely goes against religion, which at the time was a crucial part of many people’s lives. Charles’ discoveries made many people question whether they were created by God himself or were they products of nature and evolution.
Knowledge can be defined as information or facts derived from our emotion, reason, logic and perception. We strive to study the nature of knowledge, but at times, knowledge that is once “accepted…is sometimes discarded tomorrow.” To discard something is to vehemently reject it. Discarding knowledge that was once accepted raises many knowledge issues such as “To what extent is the knowledge we have temporary?” and “What causes progress in the production of knowledge?” However, the overarching issue
