The Continental Drift Theory, first proposed by Alfred Wegener in 1912, marked a significant paradigm shift in understanding the Earth's surface and its dynamic nature. Wegener suggested that the continents were not stationary but had drifted over geological time to their present positions. He introduced the concept of a supercontinent, Pangaea, which existed approximately 300 million years ago and subsequently fragmented into the continents we observe today. This theory was revolutionary at its time because it challenged the prevailing notion of a static Earth and laid the foundation for the modern theory of plate tectonics. Wegener's hypothesis was primarily based on several lines of evidence: geological, paleontological, climatological, and geomorphological. One of the most striking pieces of evidence was the jigsaw-like fit of the continental margins, especially the east coast of South America and the west coast of Africa. This observation suggested that the continents might once have been joined. Wegener also highlighted the similarity of rock formations and mountain ranges across continents that are now separated by oceans. For example, the Appalachian Mountains of North America have strong geological correlations with the Caledonian Mountains of Scotland and Scandinavia, indicating that they were once part of a continuous range.
