Understanding Plate Tectonics

The video introduces the theory of plate tectonics, explaining how mountain ranges form, what causes earthquakes, and how continents move. It covers the concept of Pangaea, tectonic plates, and their movements, including transform, divergent, and convergent boundaries. The video also discusses the Earth's layers, the role of GPS in tracking plate movements, and the formation of geological features like the Himalayas and the Mid-Atlantic Ridge. Additionally, it highlights the importance of monitoring earthquakes and volcanoes for safety.
