Continental Drift Theory and its evidence

In Class 11 Geography, this topic explains the Continental Drift Theory within the chapter “Distribution of Oceans and Continents.” Students learn Alfred Wegener’s idea that the continents were once joined as Pangaea and gradually moved apart. They examine evidence such as the matching shapes of coastlines, similar fossils, continuous rock formations, mountain belts, and past glacial deposits found on continents now far apart. The topic also introduces the theory’s limitations and its importance in the later development of plate tectonics.
