ALL CONTINENTS WERE ONCE TOGETHER IN THE SUPER CONTINENT (PANGAEA), BUT STARTED MOVING APART 225 MYA. ALFRED WEGENER COLLECTED ALL OF THIS EVIDENCE AND CREATED THE THEORY OF CONTINENTAL DRIFT =5YVFJGNJOK0 The Theory of Continental Drift

Evidence from LANDFORMS Mountain ranges on different continents line up (Africa and S. America; N. America and Europe) Coal fields on different continents line up Coastlines fit like a puzzle

Evidence from FOSSILS The same types of plant & animal fossils of the same age are found on different continents (separated by oceans, and could not have possibly crossed the oceans) When the continents are placed together, the areas where the fossils are found line-up

Evidence from CLIMATE CHANGE Tropical fossils found in places that are currently polar. (Tropical plant fossils were found in Spitzbergen, which is within the Arctic Circle)

Evidence from CLIMATE CHANGE Tropical fossils found in places that are currently polar. (Tropical plant fossils were found in Spitzbergen, which is within the Arctic Circle) Coal fields are also climate change (Coal fields were once swampy forests. Some are now found in very cold areas.)

Evidence from CLIMATE CHANGE Tropical fossils found in places that are currently polar. (Tropical plant fossils were found in Spitzbergen, which is within the Arctic Circle) Coal fields are also climate change (Coal fields were once swampy forests. Some are now found in very cold areas.) Glacial Scratches found in places that are now warm (also line up when the continets are placed together)
