Deep Earth

Deep Earth refers to the planet's interior, composed of several layers: a solid inner core, a liquid outer core, a viscous mantle, and a rigid crust. The inner core is extremely hot and dense, mainly made of iron and nickel. Surrounding it, the outer core's moving liquids generate Earth's magnetic field. The mantle, despite being solid, flows slowly over time, driving plate tectonics. These layers are studied through seismic waves from earthquakes, helping us understand Earth's formation, composition, and dynamic processes deep beneath the surface.
