Alfred Wegener was a German born Geologist and Meteorologist. He proposed the theory of continental drift in 1912 expanding on work done by an earlier scientist Abraham Ortelius in 1596.
He was first given the idea because of the shape of the continents. He was convinced that shape of the Western Africa and South America was more than mere coincidence. He also argues that the Coastlines of North America could fit onto Europe and that Antarctica, India, Australia, Madagascar and the southern tip of South America could also be fitted together as though they were a giant jigsaw. Although the evidence was compelling many scientist argued that there was just not enough sufficient evidence.
In order to get more evidence for his theory he analysed the rocks from both sides of the Atlantic Ocean and found significant similarities in rock types and distribution.
He even guessed correctly that the the Atlantic was spreading out from the Mid Atlantic Ridge.
It was not until the theory of plate techtonics was developed in the 1960's that it was widely excepted.

puzzle-like fit, climate, and animal traceings:))
In the year 1911 a German meteorologist noticed that the contents looked like the fit in together. Wegner (Veg-ner) did some research regarding the subject. Wegners theory states that parts of the Earths crust slowly drift atop a liquid core. Landforms fossils and climates helped support his theory. There were two big flaws in Wegners theory; there was no feasible explanation for the cause of Continental drift because you can be on top of something liquid and not move and that there was no evidence that continents plowed through the ocean basin. No one believed Wegner's theory. 20 years later Wegner died and then after another 20 years we developed the technology and proved Wegners theory.
he is a geologist, astronomer, and a scientists
i dont think anyone couldve tested that theory since no computer models in the 1800s. it was supported by fossil and glaciation evidence though. and offcourse later supported furthur by plate tectonics
1 counterarguement.... there was no drift because all is just as it was created. This theory works under the premise of creationism which disregards all evidence of Evolution OR If you are asking for argument were used against the theory of continental drift; it was rejected because there was no mechanism known that could cause continents to drift. It was revived when the theory of plate tectonics provided this mechanism.
The main problem with Wegners theory of continental drift was that at the time he proposed it he had no real proof.
Somewhere in Euroasia....

Wegner was the man who established the theory of "continental drift" in 1912
this is easy! I LEARNED IT IN SCIENCE! WERGNER DICOVERED IT. WEGNERS EARLIER THEORY OF CONTINENTAL DRIFT WAS REEXAMMINED AND A NEW THEORY WAS BORN ............................ THE THEORY OF PLATE TECTONICS
A scientific theory is supported by evidence. Without evidence, it is only a hypothesis.
Alferd Packer died on 1907-04-23.
Alferd Packer was born on 1842-01-21.
well if is not supported then is not a theory.
Hess checked his hair and noticed it was the same as wegners so it was that their theorys were the same
He discovered that the ocean floor moves like a conveyor belt, carrying the continents with them. This process begins at the mid-ocean ridge. Old oceanic crust go back to the mantle through trenches and molten material comes out of the mid-ocean ridge, making new crust. Harry Hess called this constant process sea-floor spreading.
