Where did Alfred Wegener live

A conference was held by the American Association of Petroleum Geologists in 1926 that was critical of the theory. This idea was basically the same as that proposed by Holmes over 30 years earlier, but now there was much more evidence to further develop and support the idea. Withering criticism was the response of most experts. This idea is based on the fact that as a substance is heated its density decreases and rises to the surface until it is cooled and sinks again. Thus taking part in continental drift.

Also in this case it was an intuitive insight and immediate observation that made him think about the origins of continental movements. Alexander du Toit wrote a rejoinder to this the following year. Even worse, his ideas rang of catastrophism. Maps of the of the ocean floors created by in cooperation with were an important contribution to the that was starting. Alfred Wegener, who is considered as one of the founding father of a major scientific breakthrough of the 20th century, was a renowned German geophysicist and polar researcher. He was the fifth child of churchman Richard and house-maker Anna Wegener. Since Wegener's day, scientists have mapped and explored the great system of oceanic ridges, the sites of frequent earthquakes, where molten rock rises from below the crust and hardens into new crust.

During the , insects such as beetles and dragonflies flourished. Unsourced material may be challenged and removed. The Austrian geologist Otto Ampferer speculated in 1906 that the Alps were formed by folding of the upper crust, as driving force he proposed magma sinking into the mantle and pulling pieces of crust downwards! And mountain chains that now lie on different continents, such as the Appalachians in the United States and the Atlas Mountains in Morocco, were all part of the Central Pangaea Mountains, formed through the collision of the supercontinents Gondwana and Laurussia. Some geologists felt that his research was hasty and selective. He did not have a mechanism for how the traits could be preserved over the succeeding generations. He died during explorations in Greenland, where his body was found the following summer, and re-buried. New ideas threaten the establishment, regardless of the century.

Most importantly Wegener considered his work as starting point and stimulus for other or even future scientists, a message that wasn't fully understand at his time. After his return in 1908 and until , Wegener was a lecturer in meteorology, applied astronomy and cosmic physics at the. In 1930, Wegener took part in his last expedition to Greenland the set up a winter weather station that would monitor the in the upper atmosphere over the north pole. The most famous of the early defenses of Darwinism was not by Darwin himself but by the famous biologist, Thomas Huxley and the social philosopher, Herbert Spencer. Though he served in World War I and was wounded twice, he published his ideas in 1915. Wegener was one of the first to realize that an understanding of how the Earth works required input and knowledge from all the earth sciences. New theories often have rough edges.

In 1924 he accepted an offer from the University of Graz Austria , where he spent fruitful years as an academic teacher and researcher. Leipzig: Verlag Von Johann Ambrosius Barth. The of the Americas fit closely to Africa and Europe, and Antarctica, Australia, India and Madagascar fit next to the tip of Southern Africa.

Darwin's theory had another problem. The expedition was led by the Dane and charged with studying the last unknown portion of the northeastern coast of Greenland. Russians also discovered that earthquakes, volcanoes and…. Later in 1913 after his return Wegener married Else Köppen, the daughter of his former teacher and mentor, the meteorologist. He then found that there were fossils of animals in a warm climate and it was also in a very cold climate.

In 1915 these ideas were then published as a book, Über den Ursprung der Kontinente und Ozeane On the Origins of the Continents and Oceans , which was revised several times. It is even possible to measure the speed of continental plates extremely accurately, using satellite technology. When the attention did come, it was overwhelmingly negative. He noticed that there was a significant similarity between matching sides of the continents, especially in. The existing theories of continent formation were allowed to survive, with little challenge until the 1960's. This resulted in German-based names for cities, streets, foods and animal breeds being changed to names that were more 'patriotic'.

Only later, in the context of the systematic exploration of the sea floor in the 1950s, did observations of the phenomenon of sea floor spreading prove his insights. Presented at the annual meeting of the German Geological Society, Frankfurt am Main January 6, 1912. Meaning 'all lands' in 1915. Darwin needed an explanation for the Cambrian Explosion and a mechanism for the preservation of traits see. From at least 1910, Wegener imagined the continents once fitting together not at the current shore line, but 200 m , at the level of the , where they match well.

Alfred Wegener and Continental Drift

Wegner himself reacted to the critics and tried to respond to them in various editions of his books, however with moderate success. Paleomagnetic data have allowed us to map past plate movements much more precisely than before. Americans were especially slow to accept continental drift. In 1916-1917, while winter and World War I both plagued the border of France and Germany, Wegener made a discovery in the Vosges Mountains. Wegener's last Greenland expedition was in 1930. He noticed mountain ranges that seemed to continue past the ocean.
