Final answer:
Alfred Wegener used lines of evidence such as the fit of the continents, matching fossils, matching mountain ranges, and paleoclimate evidence to support his theory of continental drift.
Step-by-step explanation:
Alfred Wegener proposed the theory of continental drift and used several lines of evidence to support his idea Fit of the continents Wegener noticed that the continents looked like they could fit together like pieces of a puzzle, suggesting they were once connected.Matching fossils He found that there were matching fossils on continents that were separated by oceans, indicating that they were once joined.Matching mountain ranges Wegener observed that there were similar mountain ranges on continents that were separated by oceans, suggesting they were once part of the same landmass.Paleoclimate evidence He found evidence of ancient climates on different continents that suggested they were once closer to the polar regions or equator.Wegener's theory was not immediately accepted by his peers, but it laid the foundation for the development of plate tectonics in the 1960s.
