1. Evidence of Continental Drift
Alfred Wegner

2. Documented several pieces of evidence to support his theory:
Alfred Wegner (1900’s German scientist)—stated idea of Continental Drift
Documented several pieces of evidence to support his theory:
Glacial deposits and glacial grooves/scratches
Age of Igneous Rock
Age of Mountains
Plant and animal fossil records
Jig-saw puzzle fit

3. Evidence for CONTINENTAL DRIFT
Glacial deposits and glacial grooves/scratches on rocks in India & So. Africa.
Igneous rocks (same age) throughout So. America, No. America, and Africa

4. Evidence (con’t)
Mountains (same age - 400M years old) “line up” between So. America and Africa like puzzle piece
Mountains- same age (500 million yrs old) “line up” between No. America & Europe

6. NOTE: The YELLOW AREAS on the maps represent land areas and shallow seas surrounding the continents. BLUE AREAS are deep oceans. The RED DOT shows the location of Wisconsin.

7. 100 million years in the future???

8. Fossil Evidence of Continental Drift
5th:Same plant & animal fossils found in No. America and Europe.
