Secondary
S-wave (secondary wave) seismic waves do not move through liquid materials. Unlike P-waves (primary waves), which can travel through both solids and liquids, S-waves can only propagate through solid materials due to their shear nature. This characteristic allows scientists to infer the presence of liquid layers, such as the Earth's outer core, based on S-wave behavior during seismic events.
P-waves (Primary waves) are the fastest seismic waves and travel most rapidly through the Earth's crust. They are longitudinal waves that move through solid and liquid materials, causing the particles to move parallel to the direction of wave propagation.
P-waves, or primary waves, are the type of seismic waves that can travel through liquids. These waves are compressional and move by alternately compressing and expanding the material they pass through. Unlike S-waves (secondary waves), which cannot travel through liquids, P-waves can move through both solid and liquid mediums, allowing them to be detected by seismographs even when they travel through the Earth's outer core.
The type of seismic wave that cannot pass through air and liquid is the S-wave, or secondary wave. S-waves are shear waves that require a medium with rigidity to propagate, which means they can only travel through solids. Unlike P-waves (primary waves), which are compressional waves and can move through both solids and fluids, S-waves are unable to transmit through liquids or gases.
P-waves, or primary waves, are seismic waves that can travel through all parts of the Earth, including solids, liquids, and gases. They are compressional waves that cause particles in the material they pass through to move back and forth in the same direction as the wave. This ability to travel through both the Earth's solid inner core and the liquid outer core distinguishes P-waves from S-waves, which only move through solids.

S waves cannot travel through the outer core because they can only travel through solids, and the outer core is liquid.
S-waves which are a form of seismic wave. Seismic waves are a type of mechanical wave known as a shear or transverse wave that travel through the solid Earth (but not the liquid outer core).
How do scientists use seismic waves to study the Earth
Seismic waves.
Primary (P) waves move the fastest among seismic waves. They are compressional waves that travel through the Earth's interior, and can travel through solids, liquids, and gases.
