FAQ

Those interested in the 8th grade seismic waves worksheet category often ask the following questions:

☑️ Are seismic waves?

Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion. They are the energy that travels through the earth and is recorded on seismographs. There are several different kinds of seismic waves, and they all move in different ways.

☑️ Are seismic waves compression waves?

There are four types of seismic waves, the P-wave, S-wave and the Love and Rayleigh waves. Of these four types, the P-wave is a longitudinal / compression wave.

☑️ Are seismic waves secondary?

S waves shake the ground in a shearing, or crosswise, motion that is perpendicular to the direction of travel. These are the shake waves that move the ground up and down or from side to side. S waves are called secondary waves because they always arrive after P waves at seismic recording stations.

☑️ What kind of waves are seismic waves?

p waves s waves and surface waves

☑️ Are surface waves the fastest seismic waves?

No, they are in fact the slowest! The fastest seismic waves are P-waves.

How are seismic waves different from body waves?

  • Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water.

How are seismic waves similar to other waves?

  • Seismic waves through the Earth follow the same laws of refraction and reflection as any other wave at interfaces.
