*A theory proposed by Alfred Wegner in 1915
*Continents were once joined together forming a supercontinent named Pangae meaning 'all land'.
*Evidence for Continental Drift include:
-fossils found on adjacent continents, also the animals could not have made the long swim between the continents.
-rocks on different continents show the same age and type
-climate, there are glacial deposits found in regions in the southern continents (South America, Southern Africa, Antarctica, India, and Australia) and coal fields in the eastern U.S., Europe, and Siberia would suggest that the continents were located in tropical climates with swampy areas.
*Wegner's hypothesis rejected because he could not explain how the continents would have moved.
