Detailed explanation-1: -Scientists figured out that the outer core must be liquid because S waves do not pass through it, but P waves do. The behavior of P and S waves also indicates that the inner core is solid. The speed of seismic waves also depends on the density of the material through which they are traveling.
Detailed explanation-2: -S-waves passing from the mantle to the core are absorbed because shear waves cannot be transmitted through liquids. This is evidence that the outer core does not behave like a solid substance. S-waves are not transmitted through the liquid outer core.
Detailed explanation-3: -However, unlike the outer core, the inner core is not liquid or even molten. The inner core’s intense pressure-the entire rest of the planet and its atmosphere-prevents the iron from melting. The pressure and density are simply too great for the iron atoms to move into a liquid state.
Detailed explanation-4: -S waves cannot pass through the liquid outer core, but P waves can. The waves are refracted as they travel through the Earth due to a change in density of the medium. This causes the waves to travel in curved paths.
