Alfred wenger and continental drift paper

John-Michael McIntyre 9/12/10 MYP 5 Humanities Alfred Wegener and Continental Drift

Alfred Lothar Wegener was born on November 1st,1880. He earned a Ph.D in astronomy from the University of Berlin in 1904. However he had always been fascinated in the field of geo-physics and also became fascinated in the developing fields of meteorology and climatology. During his life, Wegener made several key contributions to meteorology such as: he started the use of balloons to track air circulation, and wrote a textbook that became standard throughout Germany. In 1906 he joined an expedition to Greenland to study polar air circulation. After the expedition he became a tutor at the University of Marburg, yet still taking time to visit Greenland again in 1912-1913. In 1914 he was drafted into the German army, but was released later on from being wounded, and served in the army weather services.

In the autumn of 1911, he was browsing through the university library when he came across a scientific paper which listed fossils and plants that were found on either side of the Atlantic. Intrigued by this information he set off and looked for similar plants and fossils on either side of the Atlantic ocean. While being out in South America and looking at a map he realized that the coastlines of South America and Africa fit together like pieces in a jigsaw puzzle. That is when he created the theory of Pangea and continental drift.

He thought that at one point in time all the continents came together and created one super continent called Pangea. However after time they drifted apart and became separate continents. This is called Continetal drift. Continetal drift is the movement of continents relative to each other. The hypothesis that continents drift was first put forward by Abraham Ortelius, and Wegener just perfected it. However it was not until the development of the theory of plate tectonics, that a sufficient amount of geological evidence was found that could prove him right.

Good work Johnmichael, however there are a couple of other things he used as scientific evidence - geological in particular
