CONTINENTAL DRIFT

The Theory of Continental Drift  Proposed by Alfred Wegener in 1900

 Main points: –The continents are moving –Were once connected in a single supercontinent called Pangaea

Evidence for Continental Drift  Wegener used several different pieces of evidence for his theory:

Continent Shapes  The continents fit together like pieces of a jigsaw puzzle

Matching geological structures  Similar rock structures on opposite sides of the ocean  Ex. Newfoundland and northern Europe

Fossil evidence  Similar fossils have been found in many continents

Glaciation  Evidence of ice age glaciation in tropical areas
