Theory of Continental Drift The seven continents used to be one giant continent named Pangea. They spread apart and became what the continents are today. The shapes of the continents line up‚ the fossils line up with how the continents‚ the rock formations on both sides of the Atlantic line up with the fossils and coastlines‚ and climatic evidence proves the Theory of Continental Drift. The first piece of evidence for Continental Drift is the shapes of the continents. All of the continents fit

Hello‚ I am Alfred Wegener‚ and I believe that 250 million years ago‚ the earth was at one point joined together in one massive super continent which I call Pangaea. I know it may sound crazy‚ but I have 3 reasons for you that support my theory. My first piece of evidence is‚ that I have discovered that some fossils‚ have been found on multiple continents all across the world. One of these fossils is one called Glossopteris. Glossopteris was a fern like plant which grew abundantly a long time

Antarctica is a frozen land‚ so cold and icy that no trees can grow there. Yet scientists have discovered fossils (remains preserved in rock) of ancient trees in Antarctica. What do you think this means? That Antarctica was once a part of the

hole world looks at the land we live on in this present day. My theory is that all continents were once connected. This took place about 200 million years ago. I believe that all the continents were once together as a super continent that was called Pangaea. Today as you read this letter that I have sent to you I will explain the following things. I will tell you more about why I think the theory of continental drift really did happen many years ago‚ names and dates of historical events and places

industrial purposes‚ as well as the coal deposits of western Europe and the eastern United States‚ were formed during the Paleozoic. * The Cambrian (beginning) opened with the breakup of the world-continent Rodinia and closed with the formation of Pangaea‚ as the Earth’s continents came together once again. * This event is thought to have caused the climate changes that led to mass extinction event. * The Appalachian mountains were formed during this time. * At the end of the Paleozoic

Then I divided 240‚000‚000 by 1.25‚ and I got 192 million years. 3. How could you use this method to reconstruct Pangaea? I could use this method to reconstruct Pangaea. I could do this by calculating the distance of each of the continents from the Mid-Atlantic Ridge. Then I could convert the distance to cm‚ and divide that distance by 1.25 cm. This would tell me how long ago Pangaea was on the Mid-Atlantic Ridge. I would also be able visualize or reconstruct it. Work: (Estimated because

this supercontinent Pangaea‚ meaning “all land” and suggested that it was surrounded by a supersea‚ Panthalassa and in the Mesozoic period‚ Pangaea began to split into separate continents. (Alfred Wegener‚ 2012) In the late Triassic‚ Pangaea split into two mega continents‚ Laurasia and Gondwanaland. In present today‚ part of Pangaea lies in the Northern Hemisphere and includes North America‚ Greenland‚ Europe and Asia‚ calling this area Laurasia. In the other part of Pangaea we would find South America

inch per year. Scientists use the theory of plate tectonics to explain the long history of Earth’s surface. They believe that about a few million years ago‚ all the continents that we have now today were part of one super continental called Pangaea. Pangaea then broke into two smaller supercontinents called Gandwana and Laurasia. These two then broke into the modern continents we have today. The theory of plate tectonics helps explain the fit between the African coastlines and South America. Rock

it back home after being stranded in a different region of Pangaea‚ which is a piece of land that incorporates many terrestrial biomes. He doesn’t know how he ended up there but he knew exactly where he was headed. His methods of survival were clear and he was able to make a few friends along the way. Throughout this journey from an unknown place to his home and family he traveled through 3 different terrestrial biomes. The biomes of Pangaea are similar to the ones known in our current world today

theory of Alfred Lothar Wegener‚ a German meteorologist‚ was published; expanded editions were published in 1920‚ 1922‚ and 1929. About 300 million years ago‚ claimed Wegener‚ the continents had formed a single mass‚ called Pangaea (from the Greek for "all the Earth"). Pangaea had split‚ and its pieces had been moving away from each other ever since. Wegener was not the first to suggest that the continents had once been connected‚ but he was the first to present extensive evidence from several fields
