Continental Drift is a scientific theory that explains how the continents have moved over geological time. Proposed by Alfred Wegener in the early 20th century, it suggests that continents were once part of a single landmass called Pangaea, which gradually broke apart and drifted to their current positions. This movement is driven by the dynamics of the Earth's mantle and tectonic plates. As these plates shift, they can cause earthquakes, volcanic activity, and the formation of mountain ranges. Understanding Continental Drift helps scientists comprehend the Earth's geological history and the processes that shape our planet.
