Plate Tectonics Assignment

What evidence did Alfred Wegener use to support his theory of continental drift?
Well, one major clue was that some fossils on the South American Coast have been found on the African Coast, which show that animals could roam around on one big super-continent. Another big piece of the puzzle was the two continents South America and Africa which seem to fit together perfectly which proves that Pangaea existed.
Why didn't people believe in Wegener's Theory?
Who Were the Two Scientists Who Brought Forth Supporting Evidence To Wegener's Theory And What Was Thier Evidence?
"There were scientists who supported Wegener: the South African geologist Alexander Du Toit supported it as an explanation for the close similarity of strata and fossils between Africa and South America, and the Swiss geologist Émile Argand saw continental collisions as the best explanation for the folded and buckled strata that he observed in the Swiss Alps."
'What prompted the revival of continental drift? In large part it was increased exploration of the Earth's crust, notably the ocean floor, beginning in the 1950s and continuing on to the present day. By the late 1960s, plate tectonics was well supported and accepted by almost all geologists. We now know that Wegener's theory was wrong in one major point: continents do not plow through the ocean floor. Instead, both continents and ocean floor form solid plates, which "float" on the asthenosphere, the underlying rock that is under such tremendous heat and pressure that it behaves as an extremely viscous liquid. (Incidentally, this is why the older term "continental drift" is not quite accurate -- both continents and oceanic crust move.)"
