Alfred Wegener Hypothesis of Continental Drift
Alfred Wegeners fossil evidence for continental drift is shown on the cut-outs. The fossils of these organisms are found on lands that are now far apart.

Alfred Wegener developed the theory of _____.
. Continents drifted to their present positions. The number in the lower right represents millions of years ago. Continental drift Evidence that tensile stresses are actively pulling the lithosphere apart in an ocean ridge system is given by ________.
During the Triassic Period the immense Pangea landmass began breaking apart as a result of continental riftingA rift zone running the width of the supercontinent began to open up an ocean that would eventually separate the landmass into two enormous continents. By 1915 after having published a first article in 1912 Alfred Wegener was making serious arguments for the idea of continental drift in the first edition of The Origin of Continents and Oceans. Try to logically piece the continents together so that they form a giant supercontinent.

What Evidence Did Alfred Wegener Use To Support His Theory Of Continental DriftWegener used fossil evidence to support his continental drift hypothesis. The son of an orphanage director Wegener earned a PhD.
Alfred Wegener proposed the theory of continental drift - the idea that the Earths continents move over hundreds of millions of years of geologic time -. Use Wegeners fossil evidence to place them in the correct positions. However a German scientist named Alfred Wegener changed the scientific debate.
Although he was not the first to suggest that continents have moved about the Earth his presentation of carefully compiled evidence inspired decades of scientific debate. Continental drift large-scale horizontal movements of continents relative to one another and to the ocean basins during one or more episodes of geologic time. The name Pangaea is derived from Ancient Greek pan πᾶν all entire whole and Gaia or Gaea Γαῖα Mother Earth land.
He suggested that 200 million years ago a supercontinent he called Pangaea began to break into pieces its parts moving away from one another. Wegener published two articles about a concept called continental drift in 1912. The concept that the continents once formed a contiguous land mass was hypothesised with corroborating evidence by Alfred Wegener the originator of the scientific theory of continental drift in his 1912 publication The Origin of Continents Die Entstehung.
Supercontinent Pangaea started to break up about 200 million years ago. Based on his obser-vations Wegener proposed the hypothesis of continental drift. Alfred Wegener Alfred Wegener.
The Father of Continental Drift. The Continental Drift Hypothesis. When you are satisfied with the fit of the continents glue the land masses down on a piece of paper.
CONTINENTAL DRIFT 14. Alfred Wegener in full Alfred Lothar Wegener born November 1 1880 Berlin Germanydied November 1930 Greenland German meteorologist and geophysicist who formulated the first complete statement of the continental drift hypothesis. In that book re-issued in four successive editions up to the final one in 1936 he noted how the east coast of South America and the west coast of Africa looked as if they were once.
Proposed by Alfred Wegener in 1915. The father of the Continental Drift theory is Alfred Wegener a German scientist who believe that the continents were once all connected creating one super continent called Pangaea. This concept was an important precursor to the development of the theory of plate tectonics which incorporates it.
Click on any of the four colored regions to the left for a paleontological history of each era. Alfred Wegner was a German geophysicist who formulated the first complete statement of the continental drift hypothesis. Grooves and rock deposits left by ancient glaciers are found today on.

Continental Drift Alfred Wegners Theory In 1912 the German meteorologist Alfred Wegener 1880-1930 first proposed the theory of continental drift which state that parts of the Earths crust slowly drift on top of the mobile asthenosphere. Continents plowed through the ocean crust.
Why did Pangea break up. When Alfred Wegener first described the idea of continental drift a lack of both detailed evidence and knowledge of a force sufficient to drive the movement saw this theory not generally accepted and heavily criticised by distinguished scientists of the day Wikipedia 2014. It is linked below in the added files section.
Degree in astronomy from the University of Berlin in 1905. Continental drift was a revolutionary scientific theory developed in the years 1908-1912 by Alfred Wegener 1880-1930 a German meteorologist climatologist and geophysicist that put forth the hypothesis that the continents had all originally been a part of one enormous landmass or supercontinent about 240 million years ago before breaking apart and drifting to.
