They go faster through the inner core than the liquid outer core
Scientists use the difference in density between the inner and outer core as evidence that the inner core is solid. This was proven using seismic waves traveling through the earth.

Seismic waves
Seismic waves are the vibrations from earthquakes that travel through the earths surface and is measured bye the shaking you feel.
Earth's solid inner core influences seismic waves by acting as a boundary that alters their speed and path. P-waves (primary waves) can travel through both solid and liquid, allowing them to pass through the inner core, while S-waves (secondary waves), which can only move through solids, are reflected at the boundary between the liquid outer core and the solid inner core. This interaction creates distinct shadow zones where S-waves are absent, providing crucial information about the Earth's internal structure. Additionally, the properties of the inner core can lead to variations in wave velocity, aiding scientists in understanding the Earth's composition and dynamics.

Seismic waves affect us because they are what causes the motion from an earthquake that destroy buildings and such. The three types of seismic waves are surface waves primary waves also called P-waves and secondary waves also called S-waves.
Earthquakes are when the seismic plates on the earths crust move after pressure from on another is exceeded, seismic waves are produced after an earthquake, and can turn into a tsunami.
This is known as the epicentre.
Seismic waves are used indirectly I have a question for you is this from a chapter 9 science packet section one because I have the same.
