Exploring Plate Tectonics and Continental Drift

This video explains the concept of plate tectonics, describing how the Earth's crust is divided into tectonic plates that move slowly over the molten asthenosphere. It covers the types of plates, including oceanic and continental, and the different boundaries where plates interact, such as convergent, divergent, and transform boundaries. The video also discusses the historical formation of continents from a supercontinent called Pangaea and how modern technology like GPS is used to track plate movements and predict earthquakes.
