Understanding Plate Tectonics

The video explores the revolutionary concept of plate tectonics, which transformed our understanding of Earth's dynamic nature. It explains how tectonic movements cause earthquakes, volcanic eruptions, and the formation of mountain ranges. The video delves into the history of continental drift, the formation of the supercontinent Pangea, and the development of the plate tectonics theory in the 1960s. It also highlights the dramatic creation of the Himalayas due to the collision of the Indian and Eurasian plates.
