Seismic waves travel through solids, liquids, and gases.

The seismogram shows that P waves travel faster than S waves, as they are the first waves to arrive at the seismograph station after an earthquake occurs. P waves are compressional waves that can travel through solids, liquids, and gases, whereas S waves are shear waves that can only travel through solids.
Sound waves can travel through solids by causing particles to vibrate and pass energy along. This transmission is more efficient in solids than in liquids or gases because the particles in solids are closely packed.
Primary (P-waves) and secondary (S-waves) earthquake waves can both travel through solids, but only primary waves can also travel through liquids. This is because primary waves are compression waves that can travel through any material, while secondary waves are shear waves that cannot propagate through liquids.
Three waves can move through various materials, including solids, liquids, and gases. In solids, such as metals and rocks, the waves travel through the particles by causing vibrations. In liquids, like water and oil, the waves propagate by disturbing the fluid molecules. In gases, such as air, the waves create pressure variations as they travel through the medium.
Surface waves, specifically Love waves, can travel through liquids. Love waves are a type of surface wave that occurs on the surface of solids, liquids, and gases.
