Plate Tectonics Explained

The video explains the concept of tectonic plates, their movement, and the forces driving them. It highlights the historical skepticism about plate tectonics, the role of mantle currents, and the phenomenon of subduction. The video also discusses how some plates move faster than the underlying currents and the impact of ocean trenches and sea floor dynamics on mantle convection.
