1. Chapter 5, lesson 1
What was Wegener’s Hypothesis about the continents?
All the continents were once joined together in a single landmass and have since drifted apart.
This is know as Continental Drift
Pangaea: 250 to 300 million years ago, the most recent supercontinent

2. Evidence for Wegener's hypothesis? P. 2
Evidence from land features: piecing the puzzle together, the continents fit together and mountain ranges line up
Evidence from fossils: fossils match up the continents. Fossils found on the west coast of Africa are found on the east coast of South America.
Evidence from climate: The climate changed as the continents moved. Tropical plant fossils have been found in the artic.

3. Wegener's Hypothesis rejected p.3
He could not explain how the continents drifted… He did not know about convection in the mantle, so people did not believe any of what he said. He thought the continents dragged themselves across the ocean floor. 
