The Earth’s Layers

The video explains the four layers of the Earth: crust, mantle, outer core, and inner core. The crust is the thin outer layer, mainly composed of rock. Beneath it lies the mantle, the thickest layer, which is semi-solid and causes tectonic plate movement. The core is divided into a liquid outer core and a solid inner core, both primarily made of iron and nickel. The core generates Earth's magnetic field. The characteristics of these layers significantly impact Earth's surface processes.
