What 3 things proved the continental drift?

Three key pieces of evidence supporting continental drift include the fit of the continents, particularly how South America and Africa appear to align; the distribution of similar fossil species, such as Mesosaurus and Glossopteris, found on widely separated continents; and geological similarities, including matching rock formations and mountain ranges across different continents, which suggest they were once connected. Additionally, paleoclimatic evidence, such as coal deposits in cold regions and glacial formations in warmer areas, further supports the theory.
