Seismic waves
Earthquakes produce seismic waves that travel through the Earth.
When earthquakes occur, scientists measure them using seismographs. Earthquakes produce a number of different types of waves. Some run along the surface of the earth. Some travel through the earth. Those that travel through the earth travel at different speeds. It is possible to create similar waves in a lab and measure how those waves travel through different types of materials. Since earthquakes occur all over the world, it is possible to measure the waves from all angles. Thus, if a wave travels a small distance through the core, scientists can tell by differences in speed what it would be if it traveled through all mantle material. So with the difference in speeds in different types of waves, scientists can figure out what is in the earth's interior.
They measure how waves from earthquakes travel through the earth, and they test how waves travel through liquid and solid and goo, and they compare the results to find the consistency of the inner core and other layers of the earth.

Seismology is an Earth Science that studies earthquakes and the movement of waves through the Earth. It includes the study of tsunamis, volcanos and plate tectonics. You can read more about Seismology and Earth Sciences at the links provided below.

A mechanical wave can travel through a medium with mass and elasticity. Examples are air and water (sound waves), earth (earthquakes).

Earthquakes and minerals are related through the earth.
The Primary wave, the secondary wave, the surface wave, and the seismic wave
Earthquakes
Primary waves and secondary waves (body waves). Love waves and rayleigh waves (surface waves) do not travel through the earth's mantle. Though secondary waves do not go through liquids, the asthenosphere is only a semi-liquid, so secondary waves can still go through it.
