Title Page 8:Continental Drift Warm-up 1. Make sure that your layers of the earth foldable is complete. 2. In which specific layer does convection occur? 3. How does this affect Earth’s surface? Lithosphere-the uppermost part of the mantle and the crust (rocky/solid) Asthenosphere-the middle mantle Moves like hot tar Pangaea • Long ago, all the Earth’s continents were just one giant continent • This giant landmass that broke into our present day continents is called PANGAEA Continental Drift • The theory that the continents moved across the Earth’s surface • Theory of Alfred Wegener • Very very very slow • Inches a year Have You Ever Noticed How Certain Continents Seem to Fit Together? • Look at this picture of the world. Which continents do you think look like they could fit together? •Color the 4 different areas, 4 different colors •They do not have to be the same color. •Cut out each of the tectonic plates •Try to fit them together like a puzzle, matching the colors Glue on pg. 9 https://www.youtube.com/watch?v=gyT8Xs6Ab-k Page A-14-A15 YELLOW Evidence of Continental Drift (bottom of pg. 8) Evidence Description Fossils Climate Geology Wegener found the same fossil from the same animal in two separate continents. This indicated that the continents were once connected. There were tropical plant fossils found in Antarctica, and fossils of ice sheets found in Africa, indicating major climate changes The same rock formations were found in North America and Europe, and South America and Africa suggesting the mountains split apart.
