Continental Drift & Plate Tectonics

Front

Fossil evidence supporting Wegener's continental drift:

Back

Land-dwelling reptiles

Front

Wegener’s hypothesis of continental drift was rejected because he couldn’t explain how or why the continents moved.

Front

Evidence for plate tectonics: continents fit like a puzzle, solar flares, paleomagnetic reversals, fossils on multiple continents.

Theory of Continental Drift:

Back

All continents were once a single landmass that broke apart over millions of years.
