Alfred L. Wegener Geologist Alfred Wegener noticed similar rocks & fossil remains were found on continents which seemed to fit together He called this “super” continent called Pangaea In 1912 Wegener published the first version & died defending his theory

PANGAEA the large landmass that included all of Earth’s present day continents http://www.utexas.edu/tmm/npl/mineralogy/Mineral_Genesis/PangeaPer.jpg

Support for Continental Drift 1. SHAPE OF THE CONTINENTS Continents fit together like puzzle pieces http://www.ruby-sapphire.com/images/madagascar_sorcerers/gondwanaland.jpg http://www.kidsgeo.com/images/pangaea2.jpg

Support for Continental Drift 2. FOSSIL EVIDENCE SAME FOSSILS: DIFFERENT CONTINENTS http://fold1.ftt.uni-miskolc.hu/~foldshe/abra6/8_3.jpg Mesosaurus was incapable of swimming across a large ocean.

Support for Continental Drift 3. ROCK EVIDENCE – Mountain ranges SAME ROCK: DIFFERENT RANGE mountain ranges separated by vast oceans contain identical rocks examples are the Appalachian Mountains in the eastern U.S and the Caledonian Mountains in the British Isles.

SAME SCARS: DIFFERENT CONTINENTS Support for Continental Drift 4. GLACIAL SCARS SAME SCARS: DIFFERENT CONTINENTS

5. LOCATION OF Coal Deposits Support for Continental Drift 5. LOCATION OF Coal Deposits Coal deposits have been found in temperate and polar regions; however, coal is formed in tropical regions.
