Continental Drift• Continental Drift - the theory that all of the continents were once
joined together in a single landmass and have since drifted apart

Continental Drift• Pangaea - “all Earth” or name given to the super continent that
existed 200 million years ago

Continental Drift• Alfred Wegener, 1915
• German geologist and meteorologist
• Proposed the theory of continental drift
• Hypothesized a super continent
