... particles and so are the slower of the two. They do not transmit through liquid medium and so the inner core cannot be penetrated by S waves. S waves will however pass through the mantle this provides scientist with evidence to suggest that the outer core is not a solid structure. As S waves cannot ...

... Sound Waves • Sound waves are mechanical waves which propagate through a material medium (solid, liquid, or gas) at a speed which depends on the elastic & inertial properties of the medium. There are 2 types of wave motion for sound waves: ...

Seismic communication
Seismic communication, sometimes called vibrational communication, describes the conveying of information through seismic vibrations of the substrate. The substrate may be the earth, a plant stem or leaf, the surface of a body of water, a spider’s web, a honeycomb, or any of the myriad types of soil substrates. Seismic cues are generally conveyed by Rayleigh waves generated through vibrations on the substrate, or acoustical waves that couple with the substrate. Vibrational communication is an ancient sensory modality and it is widespread in the animal kingdom where it has evolved several times independently. It has been reported in mammals, birds, reptiles, amphibians, insects, arachnids, crustaceans and nematode worms. Vibrations and other communication channels are not necessarily mutually exclusive, but can be used in multi-modal communication.
