REVIEW (please circle) Based on evidence from land features, fossils, and climate, Wegener concluded that continents (sink / rise / move). b. PREDICT Wegener said that because continents move, they can collide with each other. How could colliding continents explain the formation of mountains? I get it! Now I know that Wegener’s hypothesis about the continents stated that I need extra help with Earth’s Structure S/P Lesson 3.1 Page 3 Fry 2015 Name: _________________________________ Date: _________________ Period: ______ Extension Activity Try to empathize with Alfred Wegner, imagine you are in his shoes. Imagine that you have been doing scientific research and have made a fantastic discovery. You have lots of evidence to support your claim however; there are a few things you still cannot explain. Please answer the following questions: How would you convince the public that you’re right? If they didn’t believe you, how would you proceed? Would YOU believe Wegner? Why or why not? __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ __________________________________________________________________________________________________________ Earth’s Structure S/P Lesson 3.1 Page 4 Fry 2015 Name: _________________________________ Date: _________________ Period: ______ What was the name of Wegener’s SUPERCONTINENT? ______________________________ (pronounced: _____ _____ _____ ) What three areas did Wegener use as EVIDENCE for his theory…? Land Features Fossils Climate What did Wegener notice about the MOUNTAINS on different continents? What did Wegener notice about GLOSSOPTERIS? What happens when a continent moves toward the EQUATOR? (Circle the correct answer.) When you put the two continents next to one another, the mountain ranges: _______________________________________ _______________________________________ What did Wegener notice about the COAL FIELDS in North America and Europe? When you put the two continents next to one another, the coal fields: _______________________________________ _______________________________________ How does this support his theory? __________________________ __________________________ He found evidence of the glossopteris ferns: ____________________________________________ ____________________________________________ Why is this weird…? __________________________ __________________________ __________________________ What did Wegener notice about MESOSAURUS and LYSTROSAURUS? He found evidence of mesosaurus and lystrosaurus, the freshwater reptiles: ____________________________________________ ____________________________________________ __________________________ _________________________________ The climate gets colder. What happens when a continent moves toward the POLES? The climate gets warmer. The climate gets colder. Where did Wegener find some of his TROPICAL FOSSILS? __________________________ __________________________ __________________________ What ultimately happened when Wegener presented his theory to others? The climate gets warmer. Can freshwater reptiles swim across whole oceans? YES NO How does this support his theory? How does this support his theory? __________________________ __________________________ __________________________ __________________________ _________________________________ _________________________________ __________________________ __________________________ _________________________________ Earth’s Structure S/P Lesson 3.1 Page 5 Fry 2015 Name: _________________________________ Date: _________________ Period: ______ PANGAEA Fossil & Mountain Chain Evidence Follow Up Questions: 1.

Color the fossils or mountains in the legend and color the symbols on each continent the same as the legend. 2.) Cut out the continents and match up the fossil and mountain evidence to recreate Pangaea. 3.) Glue the continents into place on your construction paper.

Use a separate sheet of paper if you need more room. 1. State the hypothesis of continental drift. 2. Describe the land features that provided evidence for Wegener’s hypothesis. 3. What role did the fossil Glossopteris play in Wegener’s hypothesis? 4. How did Wegener use climate evidence to support his hypothesis? 5. Why did most scientists reject Wegener’s theory for nearly half a century? Building Vocabulary Use your vocabulary sheet to fill in the blank to complete each statement. 6. All the continents were joined together in a supercontinent that Wegener called ____________________. 7. A(n) is any trace of an ancient organism preserved in rock. 8.
