Different types of seismic waves include: Surface waves: Seismic waves that travel along the Earthâs surface. Body waves: Seismic waves that travel through the Earthâs interior. There are two types: Primary waves (P waves): Body waves that compress and expand rock in the direction the waves travel (like a slinky). Secondary waves (S waves): Body waves that shake material at right angles to the direction the waves travel (like shaking a rope). Solid rock transmits S waves, but gases and liquids do not.
S wave n. A downward deflection of the QRS complex in an electrocardiogram following an R wave. secondary wave. A type of seismic body wave in which rock particles vibrate at right angles to the direction of wave travel. Secondary waves cause the rocks they pass through to change in shape. These waves are the second fastest traveling seismic waves (after primary waves) and can travel through solids but not through liquids or gases.
