LUOA Earth Science Module 8 (2023/2024) Already Passed Glossopteris was a temperate climate leaf fossil. He found it in Antarctica. How could this be? Because that fossil was supposed to have been in a temperate climate near the equator but instead was in Antartica, meaning that the continents have moved since the beginning of time. Alfred Wegener discovered rocks in the Appalachian Mountains matched rocks in _______________________. Europe and Greenland Originally, Wegener's hypothesis that the continents float and are constantly moving on the surface of the Earth was called ________________. continental drift Pangaea means ________________. all the earth According to the Pangaea model which four continents fit together? Australia, Africa, India, and South America What did Alfred Wegener find in Africa, India, South America, Australia, that showed him that they were all covered by ice at one time? glacial striations Originally, scientists of Alfred Wegener laughed at him because there was no way the continents could crash through the surface of the Earth to move. What do we know now that changed the view of scientists to accept the Continental Drift Theory? Different fossils have been found to prove that parts of other continents should be together. For example, the mesosaurus, a freshwater reptile was found Northwest part of South America and also the Southeastern part of Africa. The name of the continent first described by Alfred Wegener was called _______________. Pangea Mesosaurus was a freshwater reptile whose fossil was found in the Northwest part of South America and _________________ . this allowed Alfred Wegener to use this as scientific proof of his Continental drift theory. the southeast part of Africa Alfred Wegener proposed his idea of continental drift which later became _____________. the theory of plate tectonics Why didn't scientists in 1912 take Alfred Wegener seriously? (Choose 3) -because there was no way the continents could plow through the ocean basin -because they didn't know of any power strong enough to push the continents -because he wasn't a geologist "Slip, Slide, Collide" What forms at the collision boundary of a continental plate and a continental plate? A collision between two continental plates crunches and folds the rock at the boundary, lifting it up and leading to the formation of mountains and mountain ranges. "Plates and Boundaries" Which type of plate is the thickest? Continental crust is thicker. "Plates and Boundaries" What is the name of the type of crust that is found under the ocean? What is the name of the type of crust that is found under the land masses? The type of crust found under the ocean is called oceanic. The type of crust found under land masses is called continental crust. "Plates and Boundaries" What types of boundaries move toward each other? Give an example
