This animation explains the Theory of Continental Drift and Plate Tectonics through five key points of evidence: the matching shapes of continents, fossil evidence, rock evidence, mountain formation evidence, and glacial scarring evidence. It describes how the Earth's lithosphere is broken into tectonic plates that float on the upper mantle and move due to convection currents in the mantle driven by heat and gravity, causing the continents to drift apart and collide over time. This movement of plates also explains various natural phenomena such as earthquakes, mountain building, and volcanic activity.
