Earth's Layers and Tectonic Plates

The video explores the Earth's lithosphere, detailing its composition and structure, including the crust, mantle, and core. It explains tectonic plates and their movements, which shape the Earth's surface and cause phenomena like earthquakes and volcanic eruptions. The video concludes with instructions for further exploration.
