What's inside the Earth?

The video takes viewers on a journey through the Earth's layers, starting with the crust, the thinnest and outermost layer. It then delves into the mantle, the thickest layer, where temperatures rise significantly. The exploration continues into the outer core, a liquid layer composed of metal, and finally reaches the inner core, a solid metal ball at the Earth's center, as hot as the sun's surface. The video concludes by encouraging viewers to reflect on the Earth's structure beneath their feet.
