Study Notes
Alfred Wegener
- Proposed the theory of continental drift in 1912
- Found fossil evidence supporting his theory
- Found the same ancient rock formations on the African and South American coasts
- Found fragments of an ancient mountain range on unconnected continents
- Found glacial deposits at the equator
Continental Drift
- Theory that continents were once a single landmass called "Pangea"
- His theory wasn't widely accepted until the 1950s and 1960s
Pangea
- Supercontinent
