list down the properties of the three types of earthquake waves
Answers
Earthquakes produce three types of seismic waves: primary waves, secondary waves, and surface waves. Each type moves through materials differently. In addition, the waves can reflect, or bounce, off boundaries between different layers. The waves can also bend as they pass from one layer into another.

Featured snippet from the webPrimary are first, And Secondary are, well, second of course. P Waves are compressional which means they move through (compress) a solid or liquid by pushing or pulling similar to the way sound travels through the air. The particles of the material a P Wave pushes through move in the direction of the P wave's energy.
In seismology, S-waves, secondary waves, or shear waves (sometimes called an elastic S-wave) are a type of elastic wave, and are one of the two main types of elastic body waves, so named because they move through the body of an object, unlike surface waves.[]
In seismology, S-waves, secondary waves, or shear waves (sometimes called an elastic S-wave) are a type of elastic wave, and are one of the two main types of elastic body waves, so named because they move through the body of an object, unlike surface waves.[]The S-wave is a transverse wave, meaning that, in the simplest situation, the oscillations of the particles of the medium is perpendicular to the direction of wave propagation, and the main restoring force comes from shear stress.
In physics, a surface wave is a 90 degree wave that propagates along the interface between differing media. A common example is gravity waves along the surface of liquids, such as ocean waves. Gravity waves can also occur within liquids, at the interface between two fluids with different densities. Elastic surface waves can travel along the surface of solids, such as Rayleigh or Love waves. Electromagnetic waves can also propagate as "surface waves" in that they can be guided along a refractive index gradient or along an interface between two media having different dielectric constants. In radio transmission, a ground wave is a guided wave that propagates close to the surface of the Earth.
Answer:
Earthquakes produce three types of seismic waves: primary waves, secondary waves, and surface waves.
Explanation:
Primary waves - Primary waves (P-waves) are longitudinal and compressional waves by nature. Primary waves are pressure waves that travel much faster than any other waves through the earth to reach at seismograph stations first, therefore the name "Primary".
Secondary Waves - Secondary waves (S-waves) are transverse and shear waves in nature. Resulting in an earthquake event, Secondary waves which arrive at seismograph posts after the faster-moving P-waves and displace the ground perpendicular to the direction of transmission.
Surface Waves - Surface waves are caused when P waves and S waves come to the surface. Examples are the waves at the surface of water and air (ocean surface waves). Another example is internal waves, which can be transmitted along the interface of two water masses of different densities.
