The Moving Plates

The video discusses the initial skepticism towards Wegener's theory of continental drift due to the lack of explanation for how continents could move through the ocean floor. In the 1960s, scientists discovered undersea mountains and ridges, leading to the understanding of seafloor spreading and the development of the plate tectonics theory. This theory suggests Earth's surface is divided into tectonic plates that float and move, causing various geological processes.
