Floating on a Sea of Molten Rock

The video uses an egg to illustrate Earth's crust and tectonic plates. It explains how tectonic plates move, causing geological phenomena like earthquakes and volcanoes. Fault lines are discussed, highlighting the San Andreas Fault. Subduction zones and the Ring of Fire are explained, along with the formation of the Hawaiian Islands. The video concludes with the concept of continental drift, emphasizing the constant movement of tectonic plates.
