Continental Drift Theory

Alfred Wegener (Vegener):

Alfred Wegener (Vegener) As a young scientist, Wegener was curious about Earth’s continents. In 1910, Mr. Wegener formed a hypothesis which stated all the continents were once joined together in a giant landmass. He named this landmass PANGAEA.

Wegener used 3 types of evidence to prove his theory!:

Wegener used 3 types of evidence to prove his theory! 1.Evidence from landforms 2.Evidence from fossils 3.Evidence from climate

Evidence from landforms:

Evidence from landforms The shapes of the continents seemed to fit together. Mountain ranges and other features also lined up.

Evidence from Fossils:

Evidence from Fossils Fossils from one continent matched fossils from other continents. Wegener used both plant and animal fossils. Glossopteris : a fern found on the southern continents Mesosaurus : a freshwater swimming reptile found in Africa and South America

Evidence from Climate:

Evidence from Climate Wegener looked at certain areas on Earth and their climates He noted that the fossils he found on certain sections of Earth did not match the current climate Glacier scratches in S. Africa

PowerPoint Presentation:

Ice could not have extended this far. So...continents MUST have moved.. Evidence from Climate
