Plate Tectonics Uncovered: Movement, Boundaries, and Earth Features

The video explains plate tectonics, a process where the Earth's lithosphere is divided into tectonic plates that move over the asthenosphere. It covers the types of plates, their movements, and the boundaries where they interact, leading to geological features like mountains and earthquakes. The video also discusses the historical formation of continents and modern methods of tracking plate movements using GPS technology.
