  1. Continental Drift

  2. Who was Alfred Wagener? • German scientist that proposed that the continents were all once connected. • He named the supercontinent , Pangaea. • His idea said that the continents are slowly moving.

  3. Why did scientists not accept Wagener’s idea? • He could not provide enough evidence. • He was not a geologist. • He died trying to prove his idea.

  4. Evidence • Landforms • Fossils • Climate

  5. Landforms • South American and African mountain ranges line up and match. • Coal fields in Europe and North America also match.

  6. Fossils • A fossil is any trace of an ancient organism that has preserved in rock. • Glossopteris, a fernlike plant that flourished 250 million years ago. These were found in Africa, South America, Australia, India, and Antarctica.

  7. Climate • Areas of tropical regions now have shown evidence of glaciation. • Areas that are now polar regions, show evidence of tropical climates.

  8. Rejection • Wegener did not provide enough evidence to satisfy scientists about Pangaea. • In the 1960’s , enough evidence was finally collected to convince scientists.
