WebbEarth’s internal structure is made up of four main layers: the crust, the mantle, the outer core, and the inner core. This question focuses on which of these layers are in a liquid state. So let’s take a closer look at the physical states of each layer. The crust is the thinnest layer. It is composed of solid rock and is rigid and hard. WebbEarth’s liquid iron core convects because it is heated from beneath by the inner core. Because iron is a metal and conducts electricity (even when molten), its motion generates a magnetic field.
