Tectonic Plates and Continental Drift

The video discusses how continents appear to fit together like a puzzle, introducing Alfred Wegner's theory of continental drift, which suggests that continents were once a single landmass that drifted apart. It also highlights Iceland as a place to observe tectonic plates, which move at a rate of about 10 centimeters per year.
