1. Continental Inside Earth 1.3 Pages 28-32 Inside Earth 1.3 Pages 28-32 Drift

2. Pangaea Proposed a super continent he called Pangaea (“All Earth”) Called his hypothesis Continental Drift – Wrote the Origins of the Continents & Oceans 1915. Alfred Wegener Layers of Earth Menu

3. All continents were once together and have slowly drifted, over time, to their current locations – Pieces of Evidence: Continental Drift Fit of the Continents Landforms Climatic Evidence Fossil Evidence

5. The coast of S. America and Africa fit together like a puzzle N. America and Africa The Red Sea. Fit of the Continents

6. World Map/ CD Evidence

7. Landforms Mountain features – South African Mt. ranges line up with a mountain range in Argentina – European coal fields line up with coal fields of North America.

8. Fossil Fossil: trace of an organism preserved in rock – Mesosaurus and Lystrosaurus: reptiles that could not swim across a salty ocean – Found in places now separated by oceans which suggest that the continents were connected. Fossils

9. Glossopteris: a tropical fernlike plant – Found in cooler climates of today, suggest that the continents have since moved – Seeds were too large to be carried by wind. Fossils

10. Fossils of tropical plants were found on the island of Spitsbergen, which is in the Arctic Ocean – A harsh, polar climate covered with ice – 300 million years ago, the island had a warm and mild climate – Wegener believed it was closer to the equator. Climate

11. Glacial Evidence found as deep scratches in rocks on South Africa – The climate of S. Africa today is too mild – Suggests that S. Africa was closer to the S. Pole Climate

12. Wegener believed that the climates changed because the position of these places changed – The continent carries the fossil and rock evidence from where it formed and provide evidence for CD. Climate

13. Rejected? Wegener could not provide a satisfactory explanation for the force that pushes or pulls the continents – Geologists rejected his idea until the 1960’s CD Rift Evidence
