Other scientists did not believe him until after he died because Wegener could not tell them *why* the plates were moving. He did not know about the convection currents in the mantle yet.

Following are the most important pieces.]]> 2019-01-11 13:46:40 UTC https://padlet.com/jlawton_lander/e2mkj1f82938/wish/319655090 jlawton_lander https://padlet.com/jlawton_lander/e2mkj1f82938/wish/319655406 The most obvious piece of evidence has to do with the shape of the continents. Specifically, if you look at South America and Africa, they line up almost perfectly like puzzle pieces! The same is true about the east coast of the United States and the west coast of parts of Europe. Could this just be a coincidence?]]> 2019-01-11 13:47:21 UTC https://padlet.com/jlawton_lander/e2mkj1f82938/wish/319655406 jlawton_lander https://padlet.com/jlawton_lander/e2mkj1f82938/wish/319656059 As you know, fossils are what sometimes get left behind when living organisms die. There are a few types of animal fossils (Mesosaurus, Cynognathus, and Lystrosaurus) that have been found on different continents that are separated by oceans -- how could the same animal be living on different continents all over the world? Did they swim? That seems unlikely.]]> 2019-01-11 13:48:54 UTC https://padlet.com/jlawton_lander/e2mkj1f82938/wish/319656059 jlawton_lander https://padlet.com/jlawton_lander/e2mkj1f82938/wish/319656809 Just like the animal fossils, there have been certain plant fossils (European flora and Glossopteris) that have been found on different continents -- how could a plant move itself that far?]]> 2019-01-11 13:50:39 UTC https://padlet.com/jlawton_lander/e2mkj1f82938/wish/319656809 jlawton_lander https://padlet.com/jlawton_lander/e2mkj1f82938/wish/319657528 Okay, so the fossils on different continents are the same. That could just be a coincidence -- but what about this next one? The same exact types of rocks and rock patterns in mountain ranges have been found on different continents. If you line up the mountain ranges of the eastern US and western Europe, you will see that even the mountains match each other!]]> 2019-01-11 13:52:02 UTC https://padlet.com/jlawton_lander/e2mkj1f82938/wish/319657528 jlawton_lander https://padlet.com/jlawton_lander/e2mkj1f82938/wish/319658330 Millions of years ago, in Earth's last Ice Age, glaciers (large blocks of ice) covered the earth. When remains of these glaciers have been discovered, we have even found that the same glacier patterns have been found on different continents (across oceans)! Okay, now I'm convinced.]]> 2019-01-11 13:53:46 UTC https://padlet.com/jlawton_lander/e2mkj1f82938/wish/319658330 jlawton_lander https://padlet.com/jlawton_lander/e2mkj1f82938/wish/319659970 You can take notes how you would like. However, I would recommend using a concept map (like the one in the picture).

"Continental Drift" would go in the center shape and everything else would be connected to that center shape.]]> 2019-01-11 13:56:54 UTC https://padlet.com/jlawton_lander/e2mkj1f82938/wish/319659970
