Layers of the Earth and Plate Tectonics Explained

The video explores Earth's dynamic nature, focusing on plate tectonics. It explains Earth's compositional and mechanical layers, the history of plate tectonics theory, and the different types of plate boundaries. The video concludes with a review of how these concepts explain geological phenomena like earthquakes and volcanoes.
