Tectonic Plates 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, including oceanic and continental, and describes the different boundaries: convergent, divergent, and transform. The video also discusses the historical formation of continents from Pangaea and modern methods of tracking plate movements using GPS technology.
