Understanding Earth's Structure and Tectonic Plates

The video explains Earth's structure, consisting of four layers: inner core, outer core, mantle, and crust. The crust is divided into tectonic plates that move due to mantle activity. These movements occur at convergent, divergent, and transform boundaries, leading to phenomena like mountain formation and earthquakes. The video also discusses the historical supercontinent Pangea and how plate movements have shaped the Earth over millions of years.
