The video tutorial explains the layers of the Earth, starting with its formation and the cooling of the outer layer, known as the crust. It describes the crust as the surface we live on, covered with landforms, air, and water. The next layer, the mantle, is located beneath the crust and is characterized by its high temperature and molten rock composition. Below the mantle lies the core, which is divided into the outer core, in a liquid state, and the inner core, in a solid state, composed mainly of metals like nickel and iron. The video also touches on the phenomenon of volcanoes, where molten rocks, or lava, emerge on the Earth's surface.
